From Arabidopsis model to green revolution cereal crop varieties: studies of the co-regulation of plant growth and nitrogen metabolism

Abstract:

Modern semi-dwarf “Green Revolution” varieties (GRVs) of wheat and rice dramatically increased global grain yields during the mid to late 20th Century. GRVs are dwarf because they accumulate growth-repressing DELLA proteins. GRVs are thus high yielding because they apportion more resource to grain filling than to stem elongation, and are less susceptible to the yield-reducing effect of “lodging”. However, recent evidence suggests that GRVs have a low nitrogen-use efficiency (NUE) as a resu...
