little information is available regarding genetic variation in wild wheat relatives from iran. in this study, genetic diversity of 36 populations of wild einkorn wheat, triticum boeoticum, was studied using amplified fragment length polymorphism (aflp) primer combinations. seventeen aflp primer combinations led to amplify 979 scorable fragments ranging from 50 to 500 bp and of these, 429 (44%) ...

Abstract Medicago L. (Fabaceae; Papillionoidae) has high nutritive value, palatability, and ability to improve the soil fertility which puts it as one of world’s most important forages. genetic resources are suffering from anthropogenic destructions, overgrazing, climate change drought. Using results a previous gap analysis, prioritized species sites for in situ ex conservation, this study aims...

Knowledge about the crop biology of economic crops in Africa is needed for regulators to accurately review dossiers and conduct comprehensive environmental risk assessments (ERAs). This information allows regulators to decide whether biotech crops present a risk to biodiversity, since crossing between domesticated crops and their wild relatives could affect the adaptations of the wild species. ...

Gene flow from crops to wild relatives by sexual reproduction is one of the major issues in risk assessment for the cultivation of genetically engineered (GE) plants. The main factors which influence hybridization and introgression, the two processes of gene flow, as well as the accompanying containment measures of the transgene, are reviewed. The comparison of risks between Switzerland and Eur...

Wild crop relatives are an important source of genetic variation for improving domesticated species. Given limited resources, methods for maximizing the genetic diversity of collections of wild relatives are needed to help spread protection over a larger number of populations and species. Simulations were conducted to investigate the optimal strategy of sampling materials from populations of wi...

Introgressive hybridization has played a crucial role in the evolution of many plant species, especially polyploids. The duplicated genetic material and wide geographical distribution facilitate hybridization and introgression among polyploid species having either homologous or homoeologous genomes. Such introgression may lead to the production of recombinant genomes that are more difficult to ...
