Nutritional stress means nutrient deficiency or element toxicity that affects plant growth, development and reproduction.It is a prevalent phenomenon all over the world in agricultural production.In China, it is reported that over 85% of the arable lands have the problem of nutritional stresses including deficiency of N, P, K, Fe, Zn, and etc, and toxicity of Al, Mn, Na and etc.In responses to nutritional stresses, plants have developed various strategies to increase the bio-availability, uptake, transportation, remobilization of nutrients and so on, thus to counter the nutrient deficiency, meanwhile to decrease these to overcome toxicity.Among these strategies, the role of cell wall is far from uncovering.

生物钟作为植物节律性的调控系统，对植物的生长发育和适应环境的能力起着关键作用。然而热胁迫对生物钟元件表达的影响还鲜有报道，本研究通过TAIR网站收集已知的与clock相关的25个拟南芥基因，并在RICE-map和KOME网站得到相应的23个水稻同源基因。分析比对了这些基因的核酸核蛋白的序列特征，运用Plantcare数据库分析这些生物钟元件的启动子区域的顺式作用元件与耐热的相关性，发现其中有16个
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
