Effect of water stress on proline content and transcript levels in Lathyrus sativus

Response of Lathyrus sativus plants to water stress showed that ABA responsive genes such as PLE 25, TAS 14 and RAB 17 are synthesized constitutively, the levels of which decline gradually with increase in water stress or ABA levels. Proline accumulation was highest in leaves (65-fold) followed by s...

Description
Summary:Response of Lathyrus sativus plants to water stress showed that ABA responsive genes such as PLE 25, TAS 14 and RAB 17 are synthesized constitutively, the levels of which decline gradually with increase in water stress or ABA levels. Proline accumulation was highest in leaves (65-fold) followed by stem (56-fold), root (38-fold) and marginal increase in etiolated seedlings. Proline increase was also observed in plant parts not exposed to light.
