To better understand the roles of LsrA protein in nodulation, a series of analyses of nodules using scanning electron microscopy, genetic and biochemical approaches have been carried out. Our analyses suggest that the lsrA1 nodules contain bacteroids in the invasion and establishing zone only. The lsrA gene expression is active early in the invasion zone and activated later than bacA genes. The lost of LsrA protein dramatically reduced the expression of nifA and fixK, and completely blocked the expression of the nifH gene for nitrogenase. LsrA protein functions early in the bacteroid development and it is essential for the development nitrogen fixing bacteroids.

前期的工作中，苜蓿中华根瘤菌Rm1021中90个候选LysR基因已经被定向插入突变，并筛选在自生生长时期、共生生长时期的表型，以期寻找更多在自生状态或共生固氮中有功能的LysR转录因子。1 针对前期鉴定出的共生固氮必需的lsrA基因，我们应用了一系列扫描电子显微镜技术、生物化学、分子遗传学等方法，发现lsrA基因主要在根瘤侵染区开始表达，表达时序也在侵染阶段左右，但晚于bacA基因表达；LsrA蛋白缺失后根瘤固氮区中缺乏具有固氮能力的类菌体，nifA和fixK基因的转录水平降低，nifH基因的转录被完全阻断，因此LsrA蛋白为根瘤发育所必需，是新的根瘤发育信号传导途径成员。2 通过表型筛选我们鉴定了苜蓿中华根瘤菌的oxyR基因，并研究了它的调节特性。oxyR突变后，苜蓿中华根瘤菌对过氧化氢敏感性提高，适应性降低。

But the vegetations changes in plain zone were slower.(4) Study on the driving forces and driving mechanism of the change of vegetation cover in HHH zone The farmland vegetation area received the common drive of climate and the society factors, but climate factors were the main driving forces for annual harvest crop or biannual irrigated and dry harvest crop, and society factors were the main driving forces for biannual harvest crop or biyearly tri-harvest dry crop.

4黄淮海地区植被覆盖变化驱动力与驱动机制研究不同植被覆盖类型，其NDVI变化的驱动力不同：一年一熟粮作区植被覆盖变化受到气候和社会经济因子的共同驱动，但以气候驱动为主；一年两熟或两年三熟旱作区植被覆盖变化受到社会经济和气候因子的共同驱动，但在主要驱动因子中，社会经济的影响更大一些；一年水旱两熟粮作植被覆盖变化主要受气候因子驱动，同时，社会经济因子也会在一定程度上影响植被NDVI的变化。
