Evaluation of genetic diversity is the key principal for plant breeding, providing an opportunity to discover novel characters and alleles for breeders. In the present study, 69 durum wheat genotypes were investigated for genetic diversity using several inter-simple sequence repeat (ISSR) markers. Sixteen ISSR primers amplified a total of 163 fragments, which out 160 fragments were polymorphic....
The Japanese threadfin bream, Nemipterus japonicus, the most abundant and crucially economic Nemipterus species is widespread throughout the Indo-West Pacific. The species has been studied widely for various aspects but genetic studies are scanty. This preliminary study contributes to the species phylogeography through the study of the genetic diversity and historical demography of N. japonicus...
warning of reducing genetic diversity of abramis brama (berg, 1905) in gilan coast using ssr markers
genetic diversity is one of the three levels of biodiversity. the aim of present study was to compare levels of genetic polymorphism between wild bream populations using seven microsatellite loci. genetic diversity was investigated by studying samples collected from two regions, the coast of chamkhale and bandaranzali of gilan province. a total of seven microsatellite loci (mfw7, mfw26, mcs1eh,...
Comprehensive studies on the genetic diversity and structure of endangered species are urgently needed to promote effective conservation and management activities. The big tree rhododendron, Rhododendron protistum var. giganteum, is a highly endangered species with only two known endemic populations in a small area in the southern part of Yunnan Province in China. Unfortunately, limited informa...

Wild crop relatives are an important source of genetic diversity for crop improvement. Diversity estimates are generally lacking for many wild crop relatives. The objective of the present study was to analyze how genetic diversity is distributed within and among populations of the wild rice species Oryza glumaepatula in Costa Rica. We also evaluated the likelihood of gene flow between wild and ...
Bromeliads are greatly represented in the Atlantic Forest, although many species are threatened with extinction owing to habitat fragmentation and intense extraction for ornamental purposes. Therefore, it is necessary to conduct studies generating knowledge about genetic diversity and the distribution of this diversity among and within natural populations to establish conservation strategies. T...
