Most plant expressed sequence tag-simple sequence repeats (EST-SSRs) are not polymorphic, and it is important to learn the characteristics of highly polymorphic EST-SSRs. In this study, 357 compound and 5557 non-compound EST-SSRs, identified from the transcriptome of the Chinese bayberry (Myrica rubra 'Biqi'), were divided into 11 types based on their characteristics. Polymorphisms in all 11 ES...
Fingerprinting with molecular markers allows precise, objective and rapid variety identification. In this study, simple sequence repeat (SSR) markers were used to fingerprint the forty-eight main commercial rice cultivars under cultivation at present in Zhejiang Province, China, and identify indica and japonica subspecies including eight groups of closely related cultivars. Eighteen of the thir...
This study aimed to estimate microsatellite based genetic diversity in two lines (the selected RIRS and control line RIRC) of Rhode Island Red (RIR) chicken. Genomic DNA of 24 randomly selected birds maintained at Central Avian Research Institute (India) and 24 microsatellite markers were used. Microsatellite alleles were determined on 6% urea-PAGE, recorded using GelDoc system and the samples ...
Simple sequence repeats (SSR) polymorphism in citrus including male sterile, sterile, low fertile and fertile was examined by analyzing 28 representative accessions sampled from north of Iran. Fifty four polymorphic alleles with an average of 4.2 alleles per primer were detected from eight pairs of used primers. The lowest number of alleles was observed in TAA27, CTT01, CCSM18 and ATC09 loci wi...
Einkorn (Triticum monococcum L. ssp. monococcum) is an ancient diploid wheat species with many useful traits and used as a gene discovery model. In this research, total of 41 tetraploid accessions were tested using simple sequence repeat (SSR) markers. A 33 genotypes T. along four each (T. dicoccon durum) plant material. The analysis utilized 10 polymorphic markers, including number alleles ave...
In this study, nine microsatellite loci were isolated and characterized from the seven-spotted lady beetle, Coccinella septempunctata (Coleoptera: Coccinellidae). The loci were validated and characterized using 20 samples collected from five Korean localities. These results indicate that some loci were highly variable in terms of number of alleles (2 to 13), heterozygosity (0.10 to 0.40), and p...
We isolated nine microsatellite loci from the Guanacaste tree (Enterolobium cyclocarpum) and optimized them for future research on breeding populations of this species. Loci were screened across 53 individuals from one population and were shown to be variable with the number of alleles per locus ranging from five to 15. Polymorphic information content ranged from 0.420 to 0.900 and observed het...
Abstract Wild melon (Cucumis melo var. agrestis) commonly known as African melon grows in tropical and semi tropical regions of the world. It also known as a valuable medicinal plant has numerous pharmaceutical properties and is considered as a valuable germplasm in cultivated melons breeding. In the present study, genetic variation of sixteen wild melons, collected from Mazandaran provin...
Powdery mildew (Blumeria graminis f. Sp. Hordei) is one of the most destructive foliar diseases in barley that cause yield reduction worldwide. DNA molecular markers can be used to study the genetic diversity and better understanding of genetic predisposition to disease resistance to powdery mildew in barley at early growth stage. Selection of resistance and tolerance need to identify molecul...
The wild relatives are important sources of genes for some desirable traits and adaptation to environmental conditions that can be exploited to enrich the cultivated safflower gene pool. In this study, genetic relationship and finding chance of specific markers between three species of the genus Carthamus, including tinctorius, lanatus and oxyacantha were evaluated by 9 ISSR primers. The s...
