钙和ABA在番茄果实乙烯生物合成中的相互作用
Relationship Between Calcium and ABA in Ethylene Synthesis in Tomato Fruit
摘要
Abstract
The influence of calcium and ABA respectively on the ethylene biosynthesis was investigated in difterent stages andpattems of tomato (Lycopersicon esculentum cv. Lichun) fruit to analyze the relationship between calcium and ABA in relation toethylene biosynthesis system. The ethylene production of discs excised from mature green tomato fruits increased rapidly with 100μ mol/LABA or 100 mmol/L calcium treatment, and the increasement of the two treatments at the same time was more than that ofsingle chemical application, which suggested that these two chemicals would play their roles synergistically in the ethylene synthesisof mature green tomato fruits. It was also founded that application of the calcium chelator EGTA ( ethyleneglycol-bis(β-aminoethylether)-N,N'-tetraacetic acid) inhibited the ethylene synthesis, and the production of ethylene applied with EGTA plusABA was higher than that of treatment with EGTA alone. However, the effect changed when treated the immature fruits with thesechemicals. ABA inhibited the ethylene synthesis obviously and calcium still promoted it. We treated the immature fruit discs with bothcalcium and ABA simultaneously, the ethylene production was more than that of ABA and less than that of calcium, which indicatedthat ABA and calcium played their roles agonistly in the ethylene biosynthesis of the immature tomato fruit discs. Furthermore, theethylene release of antisence ACS immature tomato fruit discs with application of both calcium and ABA was inhibited markedly, butthe ethylene synthesis was stimulated when the mature fruits treated with ABA or calcium. All these data suggested that there weredifferent relationship between calcium and ABA in ethylene synthesis system in different patterns and stages of tomato fruit ripening.关键词
