Spring ephemerals are dominant plant species in arid and desert area in Northern Xinjiang,China,and salt-alkalization is also one of the major environmental problems in those regions.The aim of this study was to investigate how ephemeral plant Lachnoloma lehmannii response to salt stress,and whether they adapted to the extreme environment.

我们先前已报道拟南芥环核苷酸门控的离子通道(CNGC)家族的成员之一,CNGC6,是一个受热和cAMP 激活的质膜钙通道蛋白,介导热诱导的胞外Ca2+的内流,并促进植物的耐热性.然而,CNGC6 钙通道的反馈抑制机制还不知道.动物中的研究表明,CaM 反馈抑制CNGC 通道的开放.生物信息学分析显示,CNGC6 分子中包含CaM 结合位点,然而CNGC6 是否受CaM 的反馈调节还没有实验证据.本

蕾薹期是甘蓝型油菜对干旱最为敏感的时期之一.以抗旱品种秦优8 号和不抗旱品种沪油16 构建的含183 个家系的F2﹕3 群体为研究材料,在现蕾至抽薹期进行干旱胁迫处理,正常灌溉为对照.结果表明,与对照相比,干旱胁迫后群体的抽薹高度、单株鲜重和叶片萎蔫指数平均下降了52.6~55.3%,而且三个指标高度正相关.利用335 个SRAP 标记构建了一个长度为1661.9 cM的遗传图谱,通过复合区间作图

土地盐碱化造成耕地面积减少,而盐碱地对作物的主要危害之一是碱胁迫。本文使用耐盐碱棉花品种H177 作为材料,通过改良的TCA-丙酮法提取用NaHCO3/Na2CO3 混合碱液处理后的四叶期棉花的真叶总蛋白,进行双向电泳实验,分离可能的碱胁迫响应蛋白。经过研究分析得到22 个显著差异点,其中有7 个上调蛋白和15 个下调蛋白。这些蛋白与光合作用、防御机制、能量代谢等相关。在根部,共鉴定出11 个差异
