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。

BACKGROUND: Studies show that forkhead transcription factor 1 (Fox01) plays an important role in insulin resistance and the pathogenesis of type 2 diabetes.

背景：研究表明叉头转录因子1是一种新的2型糖尿病易感基因，但2型糖尿病患者与健康人的叉头转录因子1基因在转录水平上差异性的研究不多。

Next,we transfected the HOXD13 expression vector,luciferase reporter driven by EPHA7 promoter and renilla luciferase reporter into mouse C3H10T1/2 cell. Thirty six hours after transfection,relative luciferase activity was tested by luminometer.

结果显示，与野生型HOXD13蛋白相比，p.Q317R突变体对EPHA7启动子的转录激活作用明显降低，下降至野生型的13%，而p.1314L突变体对EPHA7启动子的转录激活作用也降低，但降低程度没有p.Q317R明显，为野生型的63%。

There are three copies of R fragment in the S mt-genome, and each copy contains two closely adjacent open reading frames: orf355 and orf77. Among these three copies two BamHI fragments were cloned, and the sequence analysis showed that cox1 and cox2 gene lies upstream of the R region in each fragment, respectively. However, they locate in different strands and head to head with R. In this study, we found that:(1) The expression of cox1 and cox2 is not affected by the transcription of R region;(2) The two copies of R region transcribe in large amount in the microspores, and produce transcripts of 1.6kb and 2.8kb, respectively, in the sterile microspores; However, the abundance of these two transcripts is reduced in the fertility restored microspores, realized through the mRNA decay, and this reduction occurs at the uninucleate microspore stage;(3) In the sterile microspores, the 5 terminus of the 1.6kb transcript contains a palindrome region that can fold into a stem-loop.

本研究发现：(1) cox1和cox2的转录没有受到R区转录的影响；(2)两个拷贝的R区在在不育花粉中高丰度表达，其转录本大小分别为1.6kb和2.8kb；而在育性恢复的花粉中，这两个转录本的丰度被大大降低，进一步分析表明这一结果是通过mRNA分子的降解途径来实现的，此降解过程发生在单核花粉期；(3)在不育花粉中，1.6kb转录本的5′末端具有一段可形成茎环结构的迴文对称序列，而在可育花粉中，其5′末端短缺了9个碱基；(4)在不育花粉和育性恢复的花粉中，R区转录本的加尾位点都集中位于一个3′茎环结构之后；(5)不管是在不育花粉还是育性恢复的花粉中，orf77区域内均在第52位和100位核苷酸处发生了不同频率的C向U的编辑，从而形成UGA终止密码；(6)不管是orf55-orf77的成熟转录本还是转录前体分子，都已被加上了Poly尾巴，表明已进入降解途径；在以上实验结果的基础上，本研究对S型CMS花粉育性的恢复机理进行了如下推测：在不育花粉和育性恢复的花粉中，orf77区域内均发生了终止编辑，即由RNA编辑产生了提前终止密码子。
