5% for rpoB and 99.5% for hsp65 genes. Group II consists of isolates AQ1GA1

and AQ1M06, which have similarity values to rpoB of Mycobacterium brumae of 95.1% and to hsp65 of Mycobacterium rutilum and Mycobacterium novocastrense of 92.5%. Group III consists of isolates AQ1GA3, AQ1GA4, AQ4GA9, AQ1GA10, and AQ4GA22, which have similarity values of 95.1% to rpoB of M. poriferae and Mycobacterium goodii and 95.8% to hsp65 of the isolates from Group I, a group closely related to M. poriferae. For the hsp65 gene, the sequence similarity value of 97% has been proposed Decitabine mw as a baseline for Mycobacterium species identification (McNabb et al., 2004). Based on the hsp65 gene alone, the sequence similarity between any isolate from Group II or Group III to any of the reference Mycobacterium species in the NCBI database is below 97%, suggesting that they could be considered to be unique mycobacteria, possibly comprising novel organisms at the species level. Phylogenetic trees of a concatenated alignment of the three genes showed that isolates from A. queenslandica formed a large clade with M. poriferae with a significant bootstrap confidence, suggesting that these isolates may represent a sponge-specific phylotype (Fig. 1). Within

this M. poriferae clade, they formed three individual clusters (Groups I, II, and III), suggesting the separation of these isolates into three species-level groups, a separation consistent with sequence similarity analysis. One of these clusters, Group I, contains M. poriferae itself and the M. poriferae-like strains of our isolates. Surprisingly, an isolate (FSD4b-SM) apparently closely related Roxadustat to the M. tuberculosis complex was recovered from another GBR sponge, Fascaplysinopsis sp. This isolate has similarity values of 91.3% to the rpoB gene of Mycobacterium bovis, Mycobacterium Teicoplanin africanum, and Mycobacterium parmense and 93.1% to the hsp65 gene of M. parmense. Phylogenetic trees showed a close association of the strain FSD4b-SM with the M. tuberculosis complex, forming a cluster with significant bootstrap

values. The strain of antimycobacterial Salinispora (AQ1M05) was isolated from the same specimen of A. queenslandica that yielded the mycobacteria strains. The 16S rRNA gene sequence of AQ1M05 shares 100% similarity to that of the S. arenicola type strain CNH643, and phylogenetic analysis of 16S rRNA gene demonstrated that this strain belongs to the species S. arenicola (data not shown). This S. arenicola strain was confirmed to produce rifamycin B and an additional probable rifamycin-like compound by LC–MS/MS analysis (Fig. 2). The antagonistic effect of the S. arenicola strain AQ1M05 was therefore evaluated against the representatives of each of the three Mycobacterium phylotypes (AQ1GA1, AQ4GA8, and AQ1GA9). The S. arenicola strain AQ1M05 produced antagonistic effects indicated by a growth inhibition zone against the Mycobacterium isolates AQ1GA1 and AQ4GA9, but not against the M.

The complete list of the S. Enteritidis strains, source, geographical diversity of isolates and other details are included in Table 1. Salmonella Enteritidis genomic DNA was extracted using the GenElute Bacterial Genomic DNA Kit (Sigma, St Louis, MO) according to the manufacturer’s instructions. Primers used for PCR amplification of caiC and SEN0629 locus Vadimezan concentration fragments are listed in Table 2. PCR was carried out in a PTC 100 Peltier Thermal Cycler (GMI, Ramsey, MN). PCR amplification was performed using the ReadyMix Taq PCR Reaction

Mix (Sigma) following the manufacturer’s instructions. PCR was carried out in a final volume of 50 μL using 25 μL of the ReadyMix, 0.3 μM of each primer, 1 μL of DNA extract and sterile water to make up the final volume. The PCR thermal cycling conditions included an initial denaturation at 94 °C for 5 min, 35 cycles

of denaturation at 95 °C Selleckchem RAD001 for 30 s, annealing at 55 °C for 40 s, extension at 68 °C for 60 s and final extension at 68 °C for 5 min. PCR products were purified using a QIAquick PCR purification kit (Qiagen, Hilden, Germany), according to the manufacturer’s instructions, and analysed by 1.5% agarose gel electrophoresis. Purified PCR products were sent to the University of California DNA sequencing facility at the University of California (Davis, CA) along with PCR primers for direct sequencing. Sequencing was performed in both directions to ensure accuracy. Sequences obtained in this study and those retrieved from GenBank were aligned using clustalw integrated in the freely available arb software package (Ludwig et al., 2004). Alignments were trimmed to a uniform length (corresponding to nucleotide positions 82788–83514 for caiC and 696231–697280 for SEN0629 on the genome sequence of S. Enteritidis str. 125109, accession no. AM933172). The trimmed alignments were used to construct a concatenated alignment. Phylogenetic trees based on the neighbour-joining method (Saitou & Nei, 1987) were constructed from the individual alignments as well as from the concatenated

alignment using mega version 4.0 Thalidomide package (Tamura et al., 2007). Evolutionary distances were calculated by Kimura’s two-parameter model of substitution (Kimura, 1980). Bootstrap confidence values were generated using 1000 repeats of bootstrap samplings (Felsenstein, 1985). The nucleotide sequences determined in this study have been deposited in GenBank under accession numbers JN546231–JN546434. Full alignments of all 16 sequence types displaying all bases as well as differences to sequence type 1 were deposited as a popset in GenBank. caiC encodes a probable crotonobetaine/carnitine–CoA ligase and the fragment analysed ranged from position 82788 to 83514 on the genome sequence of S. Enteritidis str. P125109, accession no. AM933172.

The cells were washed three

The cells were washed three Lapatinib chemical structure times with PBS(−). A monolayer of A549 cells infected with RSV at a multiplicity of infection (MOI) of 1 for 48 h or of uninfected A549 cells was incubated with FITC-labeled S. pneumoniae or H. influenzae cells at MOI 10 at 37 °C for 30 min. In some experiments, 20 μg mL−1 1-O-hexadecyl-2-acetyl-sn-glycero-3-phospho(N,N,N,-trimethyl)-hexanolamine or 10 μg mL−1 mouse anti-PAF receptor monoclonal antibody [11A4(clone 21)] was added 2 h before the addition of FITC-labeled bacteria. The cell monolayer was washed three times with PBS(−) and observed by fluorescence microscopy. Alternatively, the cells were

harvested with a cell scraper and then assessed by flow cytometry (FACSCalibur). Total RNA was prepared from cells using the QuickGene SP kit RNA cultured cell HC with the QuickGene-800 system (Fujifilm, Tokyo, Japan). RT-PCR was performed using the One-Step RT-PCR kit (Qiagen, Hilden, Germany) as described previously (Okabayashi et al., 2006, 2009). The quantitative nature of the RT-PCR was validated by the linearity of the determination curve obtained with various concentrations of RNA. Detection of PAF receptor mRNA was carried out with the primer set: 5′-ATGGAGCCACATGACTCCTC-3′ and

Selleckchem Antiinfection Compound Library 5′-GAGCCAGCACTGTCGGGCACTGTG-3′. The results between two groups were compared using unpaired Student’s t-test. When A549 cells were infected with RSV at MOI 1, the expressions of the PAF receptor were upregulated as detected by flow cytometry (Fig. 1a) and RT-PCR (Fig. 2a). In the presence of fosfomycin during RSV infection, the RSV-induced upregulation of the PAF receptor was significantly suppressed in a dose-dependent manner

(Figs 1b and 2a). The degree of suppression by fosfomycin was slightly less than that by an NF-κB inhibitor, PDTC. Whereas fosfomycin did not influence RSV replication, PDTC significantly suppressed RSV replication (Fig. 2b). Suppression of PAF receptor expression was Fossariinae also observed when A549 cells were post-treated with fosfomycin (4 or 12 h after RSV infection) (Fig. 1c). We examined the adhesion of FITC-labeled S. pneumoniae and H. influenzae cells to A549 cells by flow cytometry (Fig. 3). RSV infection significantly enhanced S. pneumoniae and H. influenzae adhesion to A549 cells, and this enhancement was suppressed by the addition of the PAF receptor antagonist or the anti-PAF receptor monoclonal antibody. This result indicated that the RSV-induced bacterial adhesion was via the PAF receptor on A549 cells. The bacterial adhesion was more strongly suppressed by 100 μg mL−1 fosfomycin than by 10 μg mL−1 fosfomycin (Fig. 3). Suppression of S. pneumoniae adhesion by fosfomycin was stronger than that of H. influenzae adhesion. A similar observation was made by fluorescence microscopic analysis of S. pneumoniae (Fig. 4) and H. influenzae (data not shown) adhesion. Phosphocholine on S.

Colonies were enumerated following 48 h of incubation. The MM formula is described by Myers and Nealson (Myers & Nealson, 1988). Isolates were randomly selected from each serial passage MM plate at T = 24, 48, and 96 h

and identified as ‘EH1’, ‘EH2’, and ‘EH3’, respectively. Because these strains are potentially mutator bacteria and/or GASP SB525334 in vivo mutants and GASP mutants can display the same phenotype while having garnered substantially different changes at the molecular level (Finkel, 2006), we sought to not bias results by observing only one such isolate and have chosen to study three random isolates (EH1-3). Shewanella oneidensis MR-1 wild-type and the three isolates (EH1, EH2, and EH3) obtained as described above were grown in triplicate in MM (18 mM lactate-amended, hereafter MM (L)), MM [18 mM glucose-amended; hereafter MM (G)], and MM [10 mM lactate + 10 mM glucose-amended; hereafter MM (G/L)] broths to obtain single-carbon and diauxic growth curves. The cultures were shaken at 100 r.p.m. at 25 °C, and the OD600 nm (GeneQuant pro; Amersham Biosciences) was taken periodically. Following diauxic growth, the wild-type S. oneidensis strain was transferred to the single-carbon MM (G) broth under the above growth curve conditions, and the OD600 nm was taken periodically. Likewise, the strains EH1, EH2, and EH3 were taken after diauxic growth, serially

passed four times (24-h incubations at 25 °C, shaking at 100 r.p.m.) through MM (L) broth and Small Molecule Compound Library then inoculated into MM (G) broth. The OD600 nm was taken periodically. To confirm the identity of the wild-type S. oneidensis MR-1, EH1, EH2, and EH3 strains following the extended growth curve incubations, genomic DNA from each strain was

extracted via a boiling method (Englen & Kelley, 2000), altered to initiate with 1 mL of liquid culture and conclude with a 15-min centrifugation step to eliminate cellular debris. The 16S rRNA gene was amplified using the Failsafe PCR system (premix E; Epicentre Biotechnologies) and PCR conditions (94 °C for 5 min, followed by 30 cycles of 94 °C – 30 s, 53 °C – 30 s, and 72 °C – 90 s, and a final extension step at 72 °C for 10 min) using a GeneAmp PCR System 9700 (Applied Biosystems). The following primers were used: TCL 27F: AGAGTTTGATCCTGGCTCAG and 1492R: ACGGCTACCTTGTTACGACTT. Products were sequenced by GeneWiz (NJ). The 16S rRNA sequences obtained were queries for a BLASTn analysis against the GenBank database (http://blast.ncbi.nlm.nih.gov/Blast.cgi). All were positively identified as S. oneidensis MR-1 with an E-value of 0.0. EH1, EH2, and EH3 strains were grown in MM (G) broth (25 °C, shaking at 100 r.p.m.). Periodically, 1 mL of aliquot was removed and centrifuged at 16 625 g, and the supernatant was stored at 4 °C until later high-performance liquid chromatography (HPLC) determination of glucose concentrations. HPLC was performed on a Varian 356 LC to confirm the disappearance of glucose by the cultures.

These results, which are in agreement with observations of compet

These results, which are in agreement with observations of competition for root colonization, where mutants lacking the thin flagellum were equally competitive as the parental strains, while mutants lacking the thick flagellum or both were less competitive (Althabegoiti

et al., 2010), suggest a complex role of flagellins in competitiveness. On the one hand, the effects of motility on competitiveness depended on the water status of the rooting substrate, and on the other, mutants devoid of the thin flagellum indicated that flagellin activities unrelated to motility Aloxistatin purchase might have exerted an influence. Flagellins are pathogen-related molecular patterns able to elicit plant defense responses (Nicaise et al., 2009). However, the active portion is a 22-amino acid peptide near the N-terminus called flg22, which is not conserved in rhizobial flagellins (Gómez-Gómez & Boller, 2002) including FliCI-II or FliC1-4 (J. Pérez-Giménez, unpublished data). Another possible role related to competitiveness might be in bacterial adhesion to roots; however, studies in Rhizobium leguminosarum indicated that flagellin is not an adhesin (Smit et al.,

1989). Furthermore, flagellin expression in the vermiculite is unknown. Thus, more studies are required to evaluate the nature of flagellin activities in B. japonicum. In soils at field capacity, rhizobial motility may be scarce (Madsen & Alexander, 1982; Liu et al., 1989; McDermott & Graham, 1989; López-García et al., 2002; Horiuchi et al., 2005), because chemoattractant MAPK inhibitor diffusion is slower due to the lower water potential, paths are impaired due to the tortuosity and size of the soil pores, and bacterial movement is retarded due to attachment/detachment to and from soil particles Idoxuridine (Watt et al., 2006; Tufenkji, 2007). Our results with the nonmotile double mutants are in agreement with these observations, indicating that the effect of swimming on competition for nodulation would

be restricted to situations of water saturation of the soil pores (which, in field crops, occur after irrigation or rainfall). However, much work still remains to be carried out to understand the different performances of each flagellum in laboratory and field experiments. Among the main factors that may play a role in the field situation are the physiological state of the rhizobia at the time of inoculation, the expression of each flagellum in the environment, their activities apart from motility, and the influence of soil factors such as micro- and macrobiota, organic matter, porosity, structure, and climate, all of which are absent in the lab system. Nevertheless, our results underscore the importance of inoculant application methods in field crops to benefit from rhizobial motility in the competition for nodulation (López-García et al., 2002, 2009; Althabegoiti et al., 2008).

, 2004). However, the Prevotella species that did not produce indole seemed to lack the tnaA gene altogether. A phylogenetic tree was constructed using 16S rRNA gene sequences of the Prevotella species (Fig. 4). Interestingly, the indole-producing (and tnaA-containing) Prevotella species, with the exception of P. micans,

formed a cluster that was separate from the remaining non-indole-producing Prevotella species and P. micans (Fig. 4). Presumably, the tnaA gene in P. micans JCM 16134T might have been transferred from other tnaA-containing oral bacteria such as P. intermedia and P. gingivalis. Further studies are necessary to determine whether PF-6463922 price indole production is observed in the other strains of P. micans. Several lines of new evidence suggest that indole acts as an intercellular signaling molecule (for a review, see Lee & Lee, 2010). A variety of both gram-positive and -negative bacteria produce large quantities of indole, whereas several studies, including the current study, have revealed the existence of both indole-producing and non-indole-producing species in the genus Prevotella. Indole has been shown to function as a signaling molecule for microorganisms that lack the capacity to produce indole (Kamath & Vaidyanathan, 1990; Nikaido et al., 2008; Lee et al., 2009), suggesting that the non-indole-producing Prevotella species might

Daporinad chemical structure exploit signals generated by the local bacterial consortium, as seen in Pseudomonas aeruginosa (Diggle et al., 2007). Alternatively, non-indole-producing Prevotella species might not need indole to survive. Further research is needed to elucidate the effects of indole on the physiology and virulence of Prevotella species.

“Tuberculosis is caused by the bacterium Mycobacterium tuberculosis and results in innumerable deaths across the world. The emergence of multidrug-resistant and extremely drug-resistant tuberculosis strains and its coinfection with HIV has made tuberculosis more difficult to treat. Therefore, new antimycobacterial agent(s) for both therapy and disinfection are urgently required. In this context the present study describes the antibacterial property of long-chain fatty alcohols against mycobacteria.

Isolated colonies were allowed to grow. C/EBP β expression was tested by western blotting in at least 10 different clones per plasmid transfection. Selected clones were grown in DMEM supplemented with 10% heat-inactivated fetal bovine serum, 2 mm glutamine, 100 units/mL penicillin, 0.1 mg/mL streptomycin, and 500 μg/mL G418 antibiotic (all chemicals were from Sigma-Aldrich). For western blot analysis of C/EBP β expression in CGNs, both samples from nucleo-cytosol separation

and total protein were used. To separately extract nucleic and cytosolic proteins from CGNs (Caruccio & Banerjee, 1999), CGN cell cultures from 12 rat pups were scraped, resuspended in 150 μL of extraction buffer with low salt [20 mm HEPES, pH 7.9, 10 mm NaCl, 3 mm MgCl2, 0.1% selleck inhibitor NP-40, 10% glycerol, 0.2 mm EDTA, 1 mm dithiothreitol (DTT), protease and phosphatase inhibitor cocktails] and left NVP-LDE225 research buy on ice for 10–15 min with occasional tapping. Nuclei were pelleted by centrifugation at 700 g for 5 min at 4 °C. The cytoplasmic supernatant fraction

was transferred into another Eppendorf tube. Nuclei were washed with 200 μL of washing buffer to remove NP-40 (20 mm HEPES, pH 7.9, 0.2 mm EDTA, 20% glycerol, 1 mm DTT, protease and phosphatase inhibitor cocktails), and centrifuged at 700 g for 5 min at 4 °C. Nuclei were then resuspended in 60 μL of extraction buffer with salt (20 mm HEPES, pH 7.9, 400 mm NaCl, 0.2 mm EDTA, 20% glycerol, 1 mm DTT, protease and phosphatase inhibitor cocktails), and left on ice for 45 min with periodic mixing by tapping in order to extract nuclear proteins. Following centrifugation at 14 500 g for 15 min at 4 °C, supernatants were removed, aliquoted, quickly frozen on dry ice, and stored at −80 °C. The cytoplasmic fraction was further clarified by adding a one-third

volume of cytoplasmic extraction clarification buffer (20 mm HEPES, pH 7.9, 400 mm NaCl, 0.2 mm EDTA, 40% glycerol, 1 mm DTT, protease and phosphatase inhibitor cocktails) for 30 min at 4 °C in order to equilibrate the cytoplasmic proteins with NaCl, and this was followed by centrifugation at 14 500 g for 15 min. In parallel, total samples were obtained by directly harvesting cell cultures in Laemli Sample Buffer. Sitaxentan Transfected CGNs and DAOY stable clones were lysed in lysis buffer (50 mm Tris, pH 7.4, 1 mm EDTA, 1% sodium dodecyl sulfate, protease inhibitors), and then sonicated with a tip sonicator for 5 s at 10% power output. Total protein sample content was determined with the Lowry quantification method (Lowry et al., 1951), and 30 μg of each sample was loaded per lane for western blot analysis. Samples obtained as previously described were briefly sonicated and resolved by sodium dodecyl sulfate polyacrylamide gel electrophoresis before electroblotting.

“In this study, we examined how risk and delay influence rats’ decision-making, and the role of the ventral hippocampus (VHC) and orbitofrontal cortex (OFC) in the valuation of these two factors.

We used a touchscreen testing method in which rats with VHC lesions, OFC lesions and sham control surgery made choices in two decision-making tasks. In the delay discounting task, rats chose between two visual stimuli, one of which indicated a small, immediate reward, and the other of which indicated a large, delayed reward. In the probability discounting task, two stimuli indicated, instead, a small, certain reward or a large, uncertain reward. The two lesion groups showed a double dissociation with respect to the two tasks. Rats with VHC lesions were intolerant Dimethyl sulfoxide selleck inhibitor of delay, and were strongly biased towards the small, immediate reward. However, the same rats were indistinguishable from sham controls in the probability discounting task. The opposite pattern was observed for rats with OFC lesions; they performed normally in the delay discounting task, but showed a reduced tolerance for uncertainty as compared with sham-operated controls. These data support the conclusion that the VHC and OFC contribute differentially to decision-making that involves delayed or uncertain outcomes. This provides a means

for understanding the neural basis of a range of neurological and psychiatric patients who show impaired decision-making and executive dysfunction. “
“The prevention of cone loss during retinal degeneration is a major goal of most therapeutic strategies in retinal degenerative diseases. An intriguing issue in the current research in this field is to understand why a genetic mutation that affects rods eventually leads to cone death. The main objective of the present study was to investigate to what extent rescuing rods from degeneration affects the survival of cones and prevents functional impairment of the visual performance. To this purpose, we compared rod and cone viabilities by both ex vivo and in vivo determinations in the rd10 mutant mouse, a validated model of human retinitis pigmentosa.

Therefore, the gene products of PHIEF11_004 and PHIEF11_0010 are

Therefore, the gene products of PHIEF11_004 and PHIEF11_0010 are likely to be major components of the phage head subunit. PHIEF11_008 exhibits similarity to the genes for phage scaffold proteins found in several other phages including S. pyogenes phage 10750.2, Lactobacillus johnsonii prophage Lj965, and Staphylococcus aureus phage 80alpha. Moreover, the deduced size (23 446 Da) and pI (5.1) of the product of PHIEF11_008 is well within the size range (22 241–24 369 Da) and pI values (4.7) of the scaffold proteins of these other phages. For these reasons, it would appear that PHIEF11_008 specifies the scaffold protein required for the assembly of the head. The function of the remaining

genes within this module

cannot be assigned; however, the products of several of these ORFs have similarity NSC 683864 concentration to proteins of unknown function encoded by other phages (Table 1). (3) Genes encoding proteins involved in tail subunit morphogenesis Selleckchem FK506 (PHIEF11_0011 to PHIEF11_0020): PHIEF11_0013, PHIEF11_0015, PHIEF11_0016, and PHIEF11_0020 are proposed to be genes encoding the components of the φEf11 tail. They exhibit similarity to tail components of Lactococcus, Staphylococcus, and Enterococcus phages (Table 1). The tape measure protein of bacteriophage λ determines the tail length of the virion (Katsura & Hendrix, 1984; Katsura, 1987). In the φEf11 genome, PHIEF11_0019 has an HMM match (above the curated trusted cut-off) to the tape measure domain found in many tape measure proteins (TIGRFAM TIGR02675), and also overall similarity (blastp) to the tape measure proteins of Bacillus and E. faecalis below phages (Table 1). The genes located between the major tail protein and the tape measure protein in many bacteriophages are involved in the formation of a tail initiator complex onto which the major tail protein can polymerize (Brøndsted et al., 2001). PHIEF11_0017 and PHIEF11_0018 show similarity to proteins of S. pyogenes and L. casei phages, which have unknown functions (Table 1). However, PHIEF11_0013, located upstream of the predicted major tail protein genes,

has high blastp identity to tail assembly proteins of other phages (Table 1, Fig. 1), suggesting that this may be the gene for the tail initiator complex in φEf11. Furthermore, in most bacteriophages, the genes located between the major head and the major tail genes are involved in the formation and connection of the head and tail structures (Brøndsted et al., 2001); therefore, by analogy, PHIEF11_0011 to PHIEF11_0014 may encode the proteins that serve a similar function. (4) Genes encoding lysis proteins (PHIEF11_0025 to PHIEF11_0030): The lysis module of the φEf11 genome consists of genes for a holin protein (PHIEF11_0025), an endolysin protein (PHIEF11_0026), a lysin regulatory protein (PHIEF11_0027), an amidase (PHIEF11_0028), a membrane protein (PHIEF11_0029), and a protein with a Lys M domain (PHIEF11_0030).

7%), while the dinucleotide repeats represented < 3% (Table 2). Tetranucleotide repeats constituted the second most frequent

motif (16.7%) followed by hexanucleotide (13.11%) and pentanucleotide (4.91) repeat motifs in sequences of all three formae speciales. However, the percentage of di and pentanucleotide repeat was higher in Fom. This agrees with the results from other eukaryotes, where trinucleotide repeats are overrepresented in coding region (Garnica et al., 2006). Out of 30, a total of 14 SSR markers (six from Fom, three from Foc, and five from Fol) amplified easily scorable bands ranged from 70 to 400 bp in all the isolates. Of the 14 markers, three amplified dinucleotide repeats, ten amplified trinucleotide repeats, and only one marker were able to amplify tetranucleotide

www.selleckchem.com/screening/gpcr-library.html repeat. We used three indexes (percentage of polymorphic SSRs, number of alleles per locus and PIC value) to indicate SSR polymorphism level. Among all the markers, nine Poziotinib ic50 markers (64.3%) were polymorphic, whereas rest five markers (35.7%) were monomorphic. A total of 28 alleles were amplified by 14 markers. We detected 1–4 alleles per microsatellite locus with an average of two alleles per marker. FomSSR primers amplified 10 alleles with 1.8 allele per locus, whereas FocSSR primers detected 4.0 alleles with 1.3 alleles per locus and FolSSR primers detected 14 alleles with 2.8 alleles per locus. Maximum numbers of alleles (4) were amplified by FolSSR-7, while minimum one allele was amplified with five markers viz. FomSSR-3, FomSSR-5, FomSSR-9, FocSSR-5, and FocSSR-6. Three

markers namely FomSSR-8, FolSSR-3, and FolSSR-6 amplified three alleles, while five markers namely FomSSR-2, FomSSR-6, FocSSR-3, FolSSR-2, and FolSSR-10 amplified two alleles (Table 3). Of nine polymorphic markers, eight showed 100% polymorphism and one showed 66% (FolSSR-6). On comparison of polymorphism potential of markers derived from each forma specialis, of six SSR markers from Fom and three SSR markers from Foc, only three (50%) and one (65%) markers were found polymorphic, respectively (Table 4). FolSSR markers exhibited highest percentage of polymorphism (100%), all the five markers were found polymorphic. Among the polymorphic markers, the maximum PIC value was obtained with FocSSR-5 (0.899) and minimum with FolSSR-6 (0.023), the average being 0.517. The similarity coefficient Forskolin values between isolates ranged from 0.14 to 0.96 with a mean of 0.61 for all 276 isolate combinations used in the present study. For microsatellite markers derived from Fom, the similarity coefficient values between isolates ranged from 0.22 to 1.00 with average genetic diversity of 33.1%. Similarly, with Foc-derived SSR markers, the similarity coefficients between isolates ranged from 0.4 to 1.00 with 34.5% genetic diversity. For Fol markers, similarity coefficient value ranged from 0.2 to 1.0 with an average diversity being 42.7% (Table 4). The highest similarity coefficient (0.
