The effects of root hypoxia on ethylene biosynthesis and perception have been documented in many vegetative organs, but not extensively in fruit. Therefore, in the present study, the effects of root hypoxia on ethylene biosynthesis and perception were investigated in tomato (Solanum lycopersicum L.) fruit at five stages of the maturation phase. Our results showed that root hypoxia do not affect ethylene biosynthesis in fruit, but stimulates its reception from other plant part, as indicated by the increase in the expression of ethylene receptors ETR 1 and 3.
已有大量文献记录了缺氧根对乙烯生物合成和感知的影响,在果实中则研究较少。因此,本研究在番茄(Solanum lycopersicum L.)果实成熟过程的五个阶段,探究了缺氧根对乙烯生物合成和感知的影响。结果表明,缺氧根不影响果实中的乙烯生物合成,但会刺激果实从其他植物部位接收乙烯,这表现为乙烯受体 ETR1 和 ETR3 的表达增加。
