Abstract:

?为探究淹水胁迫下BnERF调节的耐淹防御相关途径,应用RNA-seq技术,对淹水6小时后的拟南芥(Arabidopsisthaliana)野生型(WT)和转BnERF株系(E33)幼苗进行基因表达分析。结果表明,淹水3天后,E33表现出较强的耐淹性,地上部生长状况和根系发育均明显强于野生型。E33幼苗未淹水处理时相对于野生型单独上调的基因有9个,4个为膜结合蛋白,其中2个参与MAPK级联途径,其它5个参与氧化胁迫及水分调节途径;与未淹水野生型相比,无论是未淹水处理还是淹水6小时后的E33幼苗中缺氧响应、抗氧化防护及细胞、器官发育相关基因的表达量均上调。另外,淹水6小时后E33的差异基因并未完全覆盖淹水6小时后野生型的差异基因;E33幼苗中缺氧响应、氧化胁迫响应、能量的产生与转变、乙醇代谢途径中的基因以及乙烯响应因子基因的表达量都明显高于野生型。上述结果表明,BnERF直接或间接调节植物的淹水胁迫相关生理代谢途径,参与淹水胁迫的防御过程。
