Stress-responsive and developmental regulation of Delta(1)-pyrroline-5-carboxylate synthetase 1 (P5CS1) gene expression in Arabidopsis thaliana.

Abstract excerpt

Delta(1)-Pyrroline-5-carboxylate synthetase 1 (P5CS1) is the rate-limiting enzyme in the biosynthesis of proline by Arabidopsis thaliana. Results of Northern analysis using aba1, abi1, and abi3 mutants of A. thaliana suggest that the expression of the P5CS1 gene under water stress is induced via abscisic acid (ABA)-biosynthesis-dependent and -independent pathways. Expression via ABA biosynthesis does not require...
