Spread of engineered genes to wild relatives.
Over the past 20 years, it has become possible to isolate genes from microbes, plants, and animals and to insert them into a range of plant species. During the next two decades, it is likely that genetically engineered crops will become widespread in agriculture. This presents new opportunities for making plants resistant to pests and diseases, better able to withstand stressful environments, a...
متن کاملUse of wild relatives to improve salt tolerance in wheat.
There is considerable variability in salt tolerance amongst members of the Triticeae, with the tribe even containing a number of halophytes. This is a review of what is known of the differences in salt tolerance of selected species in this tribe of grasses, and the potential to use wild species to improve salt tolerance in wheat. Most investigators have concentrated on differences in ion accumu...
متن کاملEnhancing the Conservation of Crop Wild Relatives in England
Humans require resilient, rapidly renewable and sustainable supplies of food and many other plant-derived supplies. However, the combined effects of climate change and population growth compromise the provision of these supplies particularly in respect to global food security. Crop wild relatives (CWR) contain higher genetic diversity than crops and harbour traits that can improve crop resilien...
متن کاملBack into the wild—Apply untapped genetic diversity of wild relatives for crop improvement
Deleterious effects of climate change and human activities, as well as diverse environmental stresses, present critical challenges to food production and the maintenance of natural diversity. These challenges may be met by the development of novel crop varieties with increased biotic or abiotic resistance that enables them to thrive in marginal lands. However, considering the diverse interactio...
متن کاملEcogeography and utility to plant breeding of the crop wild relatives of sunflower (Helianthus annuus L.)
Crop wild relatives (CWR) are a rich source of genetic diversity for crop improvement. Combining ecogeographic and phylogenetic techniques can inform both conservation and breeding. Geographic occurrence, bioclimatic, and biophysical data were used to predict species distributions, range overlap and niche occupancy in 36 taxa closely related to sunflower (Helianthus annuus L.). Taxa lacking com...
