Phylogeographic Migrations of Phaseolus Beüm in the New World, and Consequences for Taxonomy, Conservation and Breeding
نویسنده
چکیده
Botanically beans belong to the legume tribe Phaseoleae within the Papilionoideae-Leguminosae (Freytag & Debouck 2002). Bean species are all from the Americas, and their presence in other parts of the world is due to historic movements by humans after 1492. Although Amerindians may have used several species in pre-Columbian times, only five species have been ñiUy domesticated from still existing wild forms, giving rise to thousands genotypes all depending on humans for their survival (Debouck & Smartt 1995).

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...

Over the past 50 years, thousands of rice varieties have been introduced by plant breeders to agricultural communities all over the world. Despite the improvement of attributes such as grain yield and tolerance to biotic and abiotic stresses, a significant portion of farmers still prefer local varieties over the improved cultivars. The main reasons for this perference are the absence of a dire...
متن کاملTowards conservation and breeding of Ajowan (Trachyspermum ammi) by assessing ISSR, morphological traits and germination variability
Ajowan is one of the most important members of medicinal plants of the Apiaceae, consumed by humans. The aim of this study was to explore genetic variability of 20 ajowan populations by ISSR fingerprinting and evaluation of traits at germination. Out of the 30 ISSR primers, ten generated reproducible and polymorphic bands. A total of 93 bands were detected out of which 65 were polymorphic. High...
