[Abstract]  Ethylene, the simplest gaseous plant phytohormone, is involved in the control of rice growth and development processes, but the mechanism of ethylene regulating these pathways remains unclear in rice. Recent studies have found that ethylene-signaling pathway is conserved but different between rice and Arabidopsis. The forward genetic analysis is an essential and efficient method to reveal fully the mechanism of ethylene signaling in rice plants. Here we provide a protocol of genetic analysis of rice ethylene-response mutant, including screening ethylene-response mutants, treatment with ethylene and a chemical reagent, and ethylene-responsiveness gene expression analysis. [摘要]  乙烯是最简单的气态植物激素,参与水稻生长和发育过程的控制,但乙烯调节这些途径的机制在水稻中仍不清楚。 最近的研究发现,乙烯信号通路是保守的,但在水稻和拟南芥之间存在差异。 前向遗传分析是充分揭示水稻乙烯信号传导机制的重要而有效的方法。 在这里,我们提供水稻乙烯反应突变体的遗传分析协议,包括筛选乙烯反应突变体,乙烯和化学试剂处理,和乙烯响应基因表达分析。

【背景】乙烯信号通路的关键分子元素已通过拟南芥中的分子遗传学和基因组学方法鉴定(Guo和Ecker,2004)。乙烯在水稻生长,发育和环境适应中起重要作用,包括胚芽鞘和芽伸长,通气组织发育和淹水反应(Xu et al。,2006; Fukao和Bailey-Serres,2008; Ma et al。,2010)。由于水稻和拟南芥中乙烯调节的生物过程不同,水稻可能具有独特的乙烯信号通路机制(Yang et al。,2015a)。前向遗传分析对于充分揭示水稻乙烯信号通路的机制至关重要。因此,开发一种筛选水稻中乙烯反应突变体的有效方法是先决条件。已经在拟南芥上广泛进行了基于三重反应的遗传筛选(Johnson和Ecker,1998; Stepanova和Ecker,2000)。然而,由于缺乏乙烯反应表型,水稻中的遗传筛选受到阻碍。
