水杨酸对猕猴桃乙烯合成和乙烯信号转导元件的调控
Effects of acetylsalicylic acid on kiwifruit ethylene biosynthesis and signaling components
本文研究了乙酰水杨酸（ASA)对猕猴桃(Actinidia deliciosa cv Hayward) 乙烯合成和乙烯信号转导元件编码基因的表达调控效应。研究结果表明，外源ASA处理可以抑制果肉圆片的乙烯生成，且~70 N 和 ~50 N果实果肉圆片中均具有类似的效应。为研究ASA对乙烯信号转导过程的作用，研究分析了24个乙烯信号转导元件基因（5个乙烯受体，2个CTR1同源基因，4个EIL和13个ERF）转录水平。研究发现，ASA处理可有效抑制乙烯受体基因表达，表明结果显示ASA处理不仅可抑制乙烯合成，也可抑制果实的乙烯感受。同时还发现AdERF1，AdERF3和AdERF12等元件受ASA处理显著诱导。
he effects of acetylsalicylic acid (ASA) on kiwifruit (Actinidia deliciosa cv Hayward) ethylene biosynthesis and signaling were investigated. Exogenous application of ASA inhibited ethylene production in flesh discs. In order to evaluate the effects of ASA on ethylene signaling, twenty-four ethylene signaling components (five ethylene receptors, two CTR1 like genes, four EIN3-like genes and thirteen ERF genes) were analysed at the transcriptional level. The results indicated that ASA treatment generally inhibited ethylene-induced modulation of ethylene receptor genes, which suggested that ASA inhibits fruit ripening mainly by interfering directly with ethylene biosynthesis and perception. In addition, the ethylene response factors AdERF1, AdERF3 and AdERF12 were characterized as ASA-responsive genes, and their roles in fruit stress response are also discussed.
