大麦半矮秆基因sdw1/denso的克隆与功能分析
发布时间:2021-02-08 04:49
半矮秆基因广泛用于大麦育种。迄今,已报导过30多种大麦矮秆基因。其中sdw1/denso半矮秆基因在欧美、澳大利亚等国家大量应用,是大麦育种中应用最成功的基因之一。而我国大麦矮秆育种上应用的主要基因是uzul基因。sdw1/denso基因在不同环境条件下能使株高降低10-20 cm。此外,该基因与迟抽穗、晚熟、降低千粒重和高过筛率相关。sdw1/denso基因对产量的影响因遗传背景而异。基于sdw1/denso基因适宜的株高和潜在的增产效应,故已被转入至许多大麦品种。目前,至少有4个sdw1/denso等位基因被先后报导。值得关注的是,denso基因主要用于啤酒大麦育种,而sdwl基因主要用于饲料大麦育种。综上所述,有必要克隆sdw1/denso基因,以阐明其矮秆机制,揭示该基因对农艺性状的影响,从而更好地应用于大麦育种。现将本文的主要研究及取得的结果介绍如下:1.大麦sdw1/denso候选基因的克隆比较基因组学表明,大麦sdw1/denso基因位于与水稻1号染色体sdl基因染色体存在共线性区域,而水稻sdl基因编码GA 20-氧化酶。通过PCR法在大麦中获得部分水稻sdl基因的同源...
