主要研究领域:
       花生又名落花生、长生果,是典型的地上开花地下结果的油料作物,花生开花受精之后果针开始伸长并呈现向地性生长的特性,进而将子房带入地下,经受土壤的机械压力刺激、光转暗和营养环境等一系列非生物胁迫,到达一定深度的土壤后子房开始膨大并发育成荚果。随着国内外对花生需求量的逐渐增加,改良花生品种和发展花生产业对保障我国植物食用油安全具有重要的战略意义。本实验室将根据前期研究工作,利用全基因组重测序、转录组测序及全基因组关联分析等组学技术,结合图位克隆及分子生物学方法定位、克隆和功能验证调控花生重要农艺性状的关键基因。以期实现花生种质资源创新及高产优质新品种的培育。研究内容如下:
       1.以自然群体、遗传群体和诱变群体为研究对象,结合多组学方法对控制花生重要农艺性状的关键基因/QTL进行定位和功能验证;
       2.光信号和土壤机械刺激对荚果发育的遗传调控研究;
       3.植物激素参与果针向地性和荚果膨大的信号网络调控;
       4.解析花生根瘤固氮和营养高效吸收利用的分子机制;
       5.利用常规育种与分子设计育种相结合的方法培育高产优质高抗花生新品种。
