摘要

玉米(Zea mays L.)是一种雌雄同株植物,雄花和雌花在不同的花序上——穗状花序和穗状花序上。玉米性别决定是由一系列复杂的发育信号控制的。在这里,我们鉴定了一个ems诱导的玉米雌性雄穗突变体tasselsilk1 (tsk1),并鉴定出GRASSY TILLERS1 (GT1)是致病基因。表型分析显示,tsk1突变体的雄蕊在雄穗和穗上都不能流产,导致雄穗上的不育丝长,穗上的下小花发育出一个额外的小果核。RNA-seq和CUT&;Tag分析表明,GT1通过调控JA生物合成和信号通路,特别是直接促进TASSELSEED1 (TS1)、ZmMYC2A、ZmMYC2B的表达,发挥了花器官发育的抑制因子作用。我们发现了一个新的GT1等位基因,并提出GT1通过JA生物合成和信号通路调控玉米性别决定。

GT1 regulates maize sex determination by affecting the jasmonate pathway

Maize (Zea mays L.) is a monoecious plant with male and female flowers physically separated on different inflorescences—the tassel and the ear. Maize sex determination is controlled by a series of complicated developmental signals. Here, we characterized an EMS-induced maize feminized tassel mutant,tasselsilk1 (tsk1), and identified GRASSY TILLERS1 (GT1) as the causative gene. Phenotypic analysis of tsk1 mutants revealed that pistils fail to abort in both the tassel and ear, resulting in long sterile silks in the tassel and the development of an extra small kernel from the lower floret in the ear. RNA-seq and CUT&Tag analysis indicated that GT1 functioned as a repressor for flower organ development by regulating the JA biosynthesis and signaling pathways, specifically by directly promoting the expression of TASSELSEED1 (TS1), ZmMYC2A, ZmMYC2B. Together, we identified a new allele of GT1 and proposed that GT1 functions through JA biosynthesis and signaling pathways to regulate sex determination in maize.

期刊介绍: Publishing the best original research papers in all key areas of modern plant biology from the world"s leading laboratories, The Plant Journal provides a dynamic forum for this ever growing international research community. Plant science research is now at the forefront of research in the biological sciences, with breakthroughs in our understanding of fundamental processes in plants matching those in other organisms. The impact of molecular genetics and the availability of model and crop species can be seen in all aspects of plant biology. For publication in The Plant Journal the research must provide a highly significant new contribution to our understanding of plants and be of general interest to the plant science community.
