DELLA proteins restrict cell divisions by distinct mechanisms

by Jens Sundström Swedish University of Agricultural Sciences Breeding cereal crops with reduced stem length, in so-called semi-dwarf varieties, greatly contributed to yield increases associated with the green revolution. However, the semi-dwarf genotype was also associated with reduced inflorescence size. … Continue reading
