英文摘要Interrelationship among abscisic acid (ABA) content, accumulation of free polyamines and biosyntliesis of beta-N-oxalyl-L-alpha,beta-diaminopropionic acid (ODAP) was studied in grass pea (Lathyrus sativus L.) seedlings tinder drought stress induced by 10% polyethylene glycol (PEG6000). Increase of ABA content occurred prior to that of ODAP and polyamine contents, and was found significantly positive correlation between ABA content and ODAP content. Addition of exogenous ABA increased ODAP content in leaves. Oil the other hand. pretreatment with a-difluoromethylarginine (DFMA), a polyamine biosynthesis inhibitor, significantly suppressed the accumulation of free putrescine (Put), free spermidine (Spd) and free spermine (Spin), which in turn inhibited biosynthesis of ODAP in well-watered leaves. Meanwhile, addition of exogenous Put alleviated DFMA-induced inhibition oil the biosynthesis of Put and Spd, but did not affect the biosynthesis of Split and ODAP in well-watered leaves. Same result was also achieved in drought-stressed leaves. Increasing, accumulation of ODAP was significantly correlated with increasing Spm content (R = 0.7957**) but not with that of Spd and Put. Therefore. it call be argued that ABA stimulated the biosynthesis of ODAP simultaneously with increasing the level of free Spin under drought stress condition. (c) 2006 Elsevier SAS.
