项目摘要
It is well established that plant cells must repeatedly assess and communicate their relative positions in order to allow proper development to occur. Little is known, however, about the underlying mechanisms of cell-cell communication. This project provides the basis for a long-term exploration of novel receptor kinase-dependent signal transduction pathways in Arabidopsis thaliana. It will thus also enhance our knowledge on receptor-mediated signal transduction in plants in general. The grant proposal is based on results from our previous analysis of STRUBBELIG (SUB), a gene encoding a novel type of leucinerich repeat receptor-like kinase (LRR-RLK). Genetic analysis indicated that SUB is required for apical meristem development, apical meristem size, floral organ initiation and outgrowth, and integument morphogenesis. Thus, SUB defines a novel receptor kinase-based signal transduction pathway of general importance for organogenesis. SUB and eight homologs of unknown function belong to the Arabidopsis LRR-V family of LRR-RLKs. The proposed research will be based on methods of reverse genetics, cellular and molecular biology, and biochemistry. The major focus will reside on the molecular characterization and the investigation of the biological function of the eight SUB homologs of the family. Experiments are also planned that address the intracellular localization of the proteins and their potential interactions.
众所周知,植物细胞必须反复评估和交流它们的相对位置,以便允许适当的发育发生。然而,人们对细胞间通讯的潜在机制知之甚少。本研究为长期探索拟南芥中新的受体激酶依赖的信号转导途径奠定了基础。因此,它也将提高我们的知识受体介导的信号转导在植物中一般。该拨款提案是基于我们以前对LBBELIG(LRR-RLK)的分析结果,LBBELIG是一种编码新型亮氨酸重复序列受体样激酶(LRR-RLK)的基因。遗传分析表明,顶生组织的发育,顶生组织的大小,花器官的发生和生长,珠被形态建成所需的。因此,ESTA定义了一个新的受体激酶为基础的信号转导途径的器官发生的普遍重要性。LRR-V和8个未知功能的同源物属于拟南芥LRR-RLKs家族。拟议的研究将基于反向遗传学、细胞和分子生物学以及生物化学的方法。主要的重点将在于该家族的八个同源物的分子表征和生物学功能的调查。还计划进行实验,解决蛋白质的细胞内定位及其潜在的相互作用。
