MOLECULAR RESPONSE TO WATER-STRESS IN LATHYRUS-SATIVUS

Studies on response of Lathyrus sativus plants to water stress showed that the plants recovered to pre-stressed level if revived within firs t seven days of stress. After 12 days of stress period, root weight of stressed plants was 10 times lesser than control. Lipoxygenase expres sion was the highest in leaves followed by very low levels in stems an d undetectable in roots, Lox A and B messengers were respectively 3 an d 1.5 fold more in stressed leaves than control. A -22kD polypeptide w as observed in stressed plants on SDS-PAGE.
