Dwarf alleles differentially affect barley root traits influencing nitrogen acquisition under low nutrient supply.

Abstract excerpt

Sustainable food production depends critically on the development of crop genotypes that exhibit high yield under reduced nutrient inputs. Rooting traits have been widely advocated as being able to influence optimal plant performance, while breeding-based improvements in yield of spring barley suggest that this species is a good model crop. To date, however, molecular genetics knowledge has not delivered...
