Abstract: The ethylene signal components identi?ed so far in rice include receptors, EIN2 and EIN3 homologues, and CTR1, RTE1, EBF1/2 and EIN5 homologues that are reversely conservative in dicotyledon Arabidopsis and monocotledon rice. But based on the observation of ein2 and eil1 mutants of rice that there is not strong phenotypic difference between the two mutants and wild type, we conclude that ethylene signal in rice might be more intricate than in Arabidopsis. Given that rice uses ethylene to control many processes that do not exist in Arabidopsis, it seems that new mechanisms may exist in rice ethylene signal pathway. This article reviewed ethylene signal pathways, regulation of ethylene signal, and ethylene responses in rice plants.

摘要: 迄今为止,水稻中已经鉴定的有关乙烯信号传导途径中的组分包括乙烯受体、EIN2和EIN3的同系物,CTR1、RTE1、EBF1/2和EIN5的同系物,这些组分在双子叶植物拟南芥和单子叶植物水稻中相对保守。然而,对水稻ein2和eil1突变体的研究发现,两突变体与野生型相比并没有明显的表型差异。由此可以推断,水稻中的乙烯信号可能比拟南芥中的更加复杂。水稻依靠乙烯调节生长发育的许多方面(如对低氧环境的适应),这些在拟南芥中是不存在的,这表明水稻可能在乙烯信号传导途径中存在新的组分或新的机制。文章就水稻体内乙烯信号传导途径、乙烯信号调节以及乙烯在水稻中的应答进行综述。
