Abstract Background and Objective: Paratuberculosis has been repeatedly reported from Iranian ruminant herds. The extrem fastidious nature of Mycobacterium avium subspecies paratuberculsos hinders genomic diversity studies of the pathogen. Short Sequence Repeat analysis is one of the genome-based approches recently developed to overcome this d...
Limited understanding of sweet basil (Ocimum basilicum L.) genetics and genome structure has reduced efficiency of breeding strategies. This is evidenced by the rapid, worldwide dissemination of basil downy mildew (Peronospora belbahrii) in the absence of resistant cultivars. In an effort to improve available genetic resources, expressed sequence tag simple sequence repeat (EST-SSR) and single ...
Intra-population variation of 18 cultivated carrot (Daucus carota L. ssp. sativus) populations of diverse origins was evaluated using codominant microsatellite (SSR) markers. Using 27 genomic and EST-derived SSR markers, 253 alleles were identified with a mean 9.4 alleles per marker. Most of the alleles (60.5%) were rare i.e., with the frequency ≤ 0.05 while only 3.95% of alleles occurred with ...
Microsatellite markers, also known as SSRs (Simple Sequence Repeats), have proved to be excellent tools for identifying variety and determining genetic relationships. A set of 127 SSR markers was used to analyze genetic similarity in twenty five Coffea arabica varieties. These were composed of nineteen commercially important Brazilians and six interspecific hybrids of Coffea arabica, Coffea can...
Pea (Pisum sativum L.) is an important food legume globally, and is the plant species that J.G. Mendel used to lay the foundation of modern genetics. However, genomics resources of pea are limited comparing to other crop species. Application of marker assisted selection (MAS) in pea breeding has lagged behind many other crops. Development of a large number of novel and reliable SSR (simple sequ...
Tall fescue is widely used in temperate regions throughout the world as a dominant forage grass as well as a turfgrass, in pastoral and turf industry. However, the utilization of tall fescue was limited because of its leaf roughness, poor regeneration ability and poor stress resistance. New cultivars were desirable in modern pastoral industries exceed the potential of existing cultivars. Theref...
Association of molecular markers with cold tolerance and green period in zoysiagrass (Zoysia Willd.)
Cold tolerance and the green period are key traits in the breeding of zoysiagrass (Zoysia Willd.). Identification of molecular markers associated with cold tolerance and the green period of zoysiagrass will contribute to efficient selection of elite cultivars. These two traits were measured in 96 zoysiagrass accessions in 2004 and 2005-2006, respectively. The mapping population was screened wit...
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...
