Essential role of tissue-specific proline synthesis and catabolism in growth and redox balance at low water potential.

Plant physiology - 1 Sept 2011

Sharma Sandeep, Villamor Joji Grace, Verslues Paul E

Abstract excerpt

To better define the still unclear role of proline (Pro) metabolism in drought resistance, we analyzed Arabidopsis (Arabidopsis thaliana) Δ(1)-pyrroline-5-carboxylate synthetase1 (p5cs1) mutants deficient in stress-induced Pro synthesis as well as proline dehydrogenase (pdh1) mutants blocked in Pro catabolism and found that both Pro synthesis and catabolism were required for optimal growth at low water potential...
