Photosynthetic performance of an Arabidopsis mutant with elevated stomatal density (sdd1-1) under different light regimes.

abstract：:We aim to incorporate deep root traits into future wheat varieties to increase access to stored soil water during grain development, which is twice as valuable for yield as water captured at younger stages. Most root phenotyping efforts have been indirect studies in the laboratory, at young plant stages, or using indi...
