The Arabidopsis GTL1 Transcription Factor - Plant Cell

A goal of modern agriculture is to improve plant drought tolerance and production per amount of water used, referred to as water use efficiency (WUE). Although stomatal density has been linked to WUE, the causal molecular mechanisms have yet to be determined. Arabidopsis thaliana GT-2 LIKE 1 ( GTL1 ) loss-of-function mutations result in increased water deficit tolerance and higher integrated

Calcined - Revolvy
