  大豆(Glycine max(L.)Merr)是我国重要的农作物.磷与钾是大豆必需的大量元素,磷钾亏缺降低大豆的产量和品质.已有的研究证明:磷钾养分胁迫会影响拟南芥众多基因的表达,其中包括ERF类的转录调节因子;但对于大豆磷钾胁迫响应的ERF类转录调节因子及其功能还不清楚.我们通过挖掘大豆RNA-seq数据,筛选在根系高表达的ERF类基因,发现与拟南芥RAP2.11基因高度同源的一大豆ERF基因在根、根毛和根瘤表达水平较高,推测其对大豆根系磷钾胁迫响应可能起重要作用.

随着全球气候的变暖,高温和干旱逐年加重,研究干旱条件下,植物抗高温的能力可提高品种抗干旱的潜力。因此挖掘品种抗高温干旱的潜力具有重要的意义。本研究利用T7代GmHsFA1过表达大豆植株,研究土壤水分在8% ~ 9%的干旱条件下,采用28℃、48℃两个温度处理,研究其形态、基因表达和生理生化变化。运用关联分析方法,筛选和确定抗干旱耐高温的大豆品系,为遗传改良和基因聚合的利用奠定基础。
