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。

林乾良教授将茶的疗效归纳为以下几个方面，即：少睡，安神，明目，清头目，止渴生津，清热，消暑，解毒，消食，去肥腻，下气，利水，通便，去痰，祛风解表，坚齿，治心痛，疗疮治痿，疗饥，益气力，延年益寿及其他。科学研究表明，普洱茶除了和其他茶类一样具有以上功能外，现代研究证实在以下几个方面疗效更为突出： 1。

The results showed that Pleurotus tuber-regium was solitary or tufted, it's primodium was milk-white and weight was generally 48~78g, the biggest was 220g. The structure of Pleurotus tuber-regium included three stories: the outmost story was epidermis, the middle was medulla, and the undermost was hymenium.

Furthermore, there is a great phenotypic diversity among the new strains isolated from the same host. Different groups consisted of the new strains from the same host, some were Rhizobium, some were Bradyrhizobium, such as the new strains isolated from leguminous plants of AMkora Prain, Trifolium repens Lam, Aeachynomene Mica L, Indigofera bungeana Steud.
