Possible effects of (trans)gene flow from crops on the genetic diversity from landraces and wild relatives.

Gene flow is a potential concern associated with the use of transgenic crops because it could affect genetic diversity of related landraces and wild relatives. This concern has taken on added importance with the looming introduction of transgenic crops in centers of crop domestication (Mexico, China) and those producing pharmaceutical compounds. For gene flow to take place among cultivars and t...

Investigation of Diversity of Different Agronomic and Morphological Traits in Wild Wheat Relatives

Extended Abstract Introduction and Objective: Wild relatives of wheat are one of the most important genetic resources for use in wheat breeding programs. Therefore, identifying wheat wild relatives and Awareness of the diversity in them, also protecting these species is undeniably effective in expanding the richness of the gene pool and the genetic base of new cultivars and can be a good tool ...

The Role of Biotechnology

Gene flow between crops and their wild relatives is an important process that has strong implications both for conservation of genetic diversity and for plant breeding. Introgression between wild and domesticated populations has been shown to be a widespread phenomenon in most species, both those allogamous and autogamous. The combined effects of gene flow and selection on the structure of gene...

Patterns of Gene Flow between Crop and Wild Carrot, Daucus carota (Apiaceae) in the United States

Studies of gene flow between crops and their wild relatives have implications for both management practices for cultivation and understanding the risk of transgene escape. These types of studies may also yield insight into population dynamics and the evolutionary consequences of gene flow for wild relatives of crop species. Moreover, the comparison of genetic markers with different modes of inh...

Genetic diversity in Oryza glumaepatula wild rice populations in Costa Rica and possible gene flow from O. sativa

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 ...
