摘要:
TAPETUM DETERMINANT1(TPD1)基因编码1个含176个氨基酸的配体蛋白,依赖于EMS1基因编码的富亮氨酸(LRR-RLK)蛋白受体激酶参与花粉形成的调控并可在心皮进行异位表达,参与心皮形态建成。为探讨TPD1基因在荠菜心皮形态建成中的表达模式,采用同源克隆法从荠菜中克隆CbTPD1基因启动子构建GUS融合表达载体CbTPD1pro::GUS,通过根癌农杆菌介导的浸花序法转化Columbia生态型拟南芥。对T1代幼苗、花序、心皮等组织部位进行GUS染色观察。结果表明,荠菜CbTPD1基因在幼苗、花丝、柱头、蜜腺、早期果荚等部位均有表达,但在花药中未见表达,与AtTPD1在花药中的表达模式存在差异。该结果为研究AtTPD1、CbTPD1基因在拟南芥、荠菜心皮形态建成中的作用提供了有价值的依据。
