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