摘要:
甘蓝型油菜(Brassica napus L.)是我国主要油料作物之一,为国家粮油安全提供了重要保障。干旱严重限制了油菜种植规模扩大、产量与品质提升。为挖掘甘蓝型油菜抗旱的关键基因,阐明油菜耐旱机制,本研究以甘蓝型油菜湘油15为对象,通过实验室模拟干旱处理后的叶片为材料进行转录组测序(RNA-Seq)、生物信息分析并 qRT-PCR 验证。发现转录组样本平均Clean baseas约为9.6 G,且各样品碱基百分比(Q30)大于93.21%,比对到参考基因组上的Reads在89%以上。干旱处理4 h后,湘油15出现了440个差异表达基因(DEGs),其中148个基因上调,292个基因下调。随机选取10个基因(上调与下调各5个)进行qRT-PCR验证,其中9个基因的qRT-PCR结果与 RNA-Seq结果相符,仅1个基因表达趋势相反,相似度可达90%,证实转录组测序结果的可靠性。结果表明甘蓝型油菜湘油15主要通过光合作用、碳代谢和渗透调节等途径调节抗旱能力,为进一步阐明油菜耐旱机制奠定了基础。
