乙烯和脱落酸（阿坝）对植物的生长发育和逆境反应有密切的影响。阿坝对乙烯生物合成的调控机制目前还不清楚。在我们最近的研究中，HY 5-AtERF 11调节子被证明与阿坝作用和乙烯生物合成有关。本文通过分析乙烯过量产生突变体中阿坝合成基因的表达和阿坝含量，证明HY 5-AtERF 11调节子靶基因对乙烯产生的影响增加了阿坝合成基因的表达及其含量。此外，我们还讨论了HY 5可能作为多种激素对光反应的汇聚点。
Ethylene and abscisic acid (ABA) have compact effects on plant development and stress responses. It is not well understood about the mechanism of ABA modulation in ethylene biosynthesis. In our recent research, HY5-AtERF11 regulon was evidenced to connect the ABA action and ethylene biosynthesis. In this paper, by analyzing the expression of ABA biosynthesis genes and the ABA concentration in ethylene over-production mutants, we demonstrated that ethylene production affected by HY5-AtERF11 regulon targeted gene increased the expression of ABA biosynthesis genes and its contents. In addition, we discussed that HY5 might function as a convergence point of multiple hormones in response to light.
