主要研究方向
植物营养分子生物学、植物根功能基因组学及小麦抗病基因的分离。
主要研究内容
1. 植物营养分子生物学
植物的生长发育需要十多种矿质营养元素。任何一种必需元素的缺乏将影响植物的生长发育,最终导致产量和品质下降。氮、磷、铁是世界范围内三大主要限制农作物生长发育的矿质营养元素。创新研究组的工作重点是研究植物从土壤中对磷、铁两种矿质元素的吸收代谢分子生物学;分离与磷、铁吸收代谢相关的基因并阐明它们在控制磷、铁元素吸收代谢中的机理。在铁元素吸收方面,用图位克隆法从西红柿基因组中分离出了控制铁元素吸收代谢的两个关键基因(chloronerva and fer),目前正在进行分子生物学方面的研究。在磷元素的研究中,正进行pds基因的图位克隆。该研究得到中国科学院“百人计划”和“十.五”国家863课题资助。
2. 根功能基因组学
根是植物生长发育的基础。然而,由于植物根部的研究难度大,再加上根部功能基因致死突变体在模式植物拟南芥和水稻中难以保存,极大地限制了根部重要功能基因的研究。西红柿是一个二倍体栽培作物,基因组相对较小(950 Mb),有很好的细胞和分子遗传学研究基础,并已建起了一套非常有效的图位克隆分离基因体系。与水稻和拟南芥相比,以西红柿为模式植物研究根功能基因的最大优点是易嫁接,根功能基因缺陷型致死突变体可通过嫁接得以保存和繁殖。创新研究组应用化学和物理两种方法处理西红柿种子,建立突变群体,筛选根部功能基因致死型突变体,嫁接到野生型植株,加以保存和繁殖。力求建立一个较完整的根功能基因缺陷致死型突变体文库,用于根功能基因组学研究。该项目得到中国科学院“知识创新工程领域前沿项目”资助。
3. 小麦抗病基因的分离
小麦生产受到各种病虫害的威胁。小麦叶锈病是小麦生产中最为普遍的一种病害,其流行将严重影响小麦产量和品质。创新研究组选择小麦叶锈病第一抗病基因为目的基因从事小麦图位克隆。已建立一套有效的小麦大群体单株DNA分析方法。并将目的基因LR1精确定位于小麦5D染色体末端的两个紧密连锁的RFLP markers之间, 两个RFLP标记之间的物理距离大约为250 kb 左右。染色体步移目前正在进行之中。LR1基因的克隆将建立一套适用于小麦的图位克隆方法,为有效地分离小麦重要农艺性状基因提供技术平台。通过对小麦叶锈病第一抗病基因的分离及分子生物学研究,将为培育新的小麦叶锈病抗病品种提供理论基础。此研究得到国家自然科学基金的资助。
