out of fifty-two iranian nonaflatoxigenic strains of aspergillus flavus, which were collected from various substrates (soil and kernel) and sources (peanut, corn and pistachio), fifteen representatives were selected according to their different geographical origins (six provinces: guilan and golestan, ardebil, fars, kerman and semnan) and vegetative compatibility groups (vcgs, ir1 to ir15) for ...

Chinese jujube (Ziziphus jujuba), an economically important species in the Rhamnaceae family, is a popular fruit tree in Asia. Here, we surveyed and characterized simple sequence repeats (SSRs) in the jujube genome. A total of 436,676 SSR loci were identified, with an average distance of 0.93 Kb between the loci. A large proportion of the SSRs included mononucleotide, dinucleotide and trinucleo...

Three kinds of genetic markers including simple sequence repeats (SSRs), single nucleotide polymorphisms (SNPs) and sequence characterized amplified regions (SCARs) were developed from Aphanomyces euteiches. Of 69 loci tested, seven SSR, two SNP and two SCAR markers were codominantly polymorphic. These codominant markers and dominant markers described herein will facilitate population genetic a...

Microsatellites are simple sequence repeats (SSRs) showing complex patterns of length, motif sizes, motif sequences, and repeat perfection. We studied the structure of the dinucleotide SSR population at the genome level by analyzing assembled DNA sequence across species. Three dinucleotide populations were distinguished when SSR genome frequency was analyzed as a function of repeat length and r...

Simple sequence repeats (SSRs) are present abundantly in most eukaryotic genomes. They affect several cellular processes like chromatin organization, regulation of gene activity, DNA repair, DNA recombination, etc. Though considerable data exists on using nuclear SSRs to infer phylogenetic relationships, the potential of chloroplast microsatellites (cpSSR), in this regard, remains largely unexp...

A significant fraction of the nuclear DNA of all eukaryotes is comprised of simple sequence repeats (SSRs). Although these sequences are widely used for studying genetic variation, linkage mapping and evolution, little attention had been paid to the chromosomal distribution and cytogenetic diversity of these sequences. In this paper, we report the distribution characterization of mono-, di-, an...

Because of its popularity as an ornamental plant in East Asia, mei (Prunus mume Sieb. et Zucc.) has received increasing attention in genetic and genomic research with the recent shotgun sequencing of its genome. Here, we performed the genome-wide characterization of simple sequence repeats (SSRs) in the mei genome and detected a total of 188,149 SSRs occurring at a frequency of 794 SSR/Mb. Mono...

The recently acquired genome sequence of globe artichoke (Cynara cardunculus var. scolymus) has been used to catalog the genome's content of simple sequence repeat (SSR) markers. More than 177,000 perfect SSRs were revealed, equivalent to an overall density across the genome of 244.5 SSRs/Mbp, but some 224,000 imperfect SSRs were also identified. About 21% of these SSRs were complex (two stretc...
