CONTROL OF CELL SHAPE BY THE FRC2 GENE IN ARABIDOPSIS

18. 本奖学金培训的最终目标是培养一名在遗传学和分子生物学方面受过多学科培训的全面发展的研究人员，并提供在发育生物学方面的广泛背景。为了实现这一目标，奥本海默博士和我制定了一项研究计划，将课程学习和实验室经验结合起来。该课程将为学生解决问题的能力、抽象思维过程和创造力的发展提供框架。我们认为这些课程将帮助我发展成为一个具有广泛分析思维能力的研究人员。此外，拟议的奖学金培训将提供经典遗传分析（单和双突变体分离、分析和遗传制图）和现代分子技术（克隆、双杂交分析、转基因植物的构建）方面的正式培训。我们相信，通过参与培养这些技能的研究培训，同时结合遗传学和分子生物学中常用的技术，我将发展成为一名独立的研究人员，其培训将成为研究界的一笔财富。赞助商19。姓名和学位(S)奥本海默，大卫·g·b.s.ph d20.。职位/职衔助理教授研究方向：植物细胞形态的遗传与分子控制，细胞扩增的细胞骨架控制，植物运动蛋白功能，植物毛状体形态发生，植物发育本研究的长期目标是更深入地了解细胞形成形状的过程。虽然拟南芥是本研究计划的主题，但从了解植物细胞发育中获得的知识有可能应用于动物细胞发育。该提案中提到的一个基因ZWI说明了这一点。ZWI的产品KCBP以前被认为只存在于植物界。最近，在动物细胞（海胆）中发现了一种相关的蛋白质，运动蛋白- c，它被认为在发育中起作用。因此，植物中与KCBP相互作用的基因可能在动物细胞中有未被发现的对应基因。因此，从研究影响植物细胞形状的基因中学到的知识可能在更广泛的范围内适用于人类。该研究的直接目标是鉴定FRC2基因产物，该基因已知在拟南芥中控制毛状体分支数量，并测试其在细胞形状发育中的功能预测。拟开展研究的具体目标是：克隆FRC2基因并鉴定其产物，直接验证FRC2对ZWI和FRC4都是冗余的假设，验证FRC2产物与ZWI产物相互作用的假设，分离frc突变的抑制因子和/或修饰因子。PHS416-1 （Rev. 12/98）表格第2页BB cc姓名（最后，第一，中间首字母）个人NRSA申请表格Conte Jeffries， StaceyJ页码(在整个申请过程中，页码在底部连续编号。不要使用第1节申请人后缀，如5a，5b。)Face Page（第1 -8项）15),表单页面2(项目16 - 22),和表的内容 ======================================== 节结束 ===========================================

18. GOALS FOR FELLOWSHIP TRAINING AND CAREER The ultimate goal of this fellowship training is to create a well-rounded researcher with multidisciplinary training in Genetics and Molecular Biology, as well as provide a broad background in Developmental Biology. To achieve this goal, Dr. Oppenheimer and I have developed a research plan that will incorporate both course work and lab experience. The coursework will provide the framework for the development of problem solving abilities, abstract thinking processes, and creativity. We feel these courses will help me develop into a researcher with extensive analytical thinking abilities. In addition, the proposed fellowship training will provide formal training in classical genetic analysis (single and double mutant isolation, analysis and genetic mapping) and modern molecular techniques (cloning, two-hybrid analysis, construction of transgenic plants). We believe that by participating in research training that develops these skills, while incorporating techniques frequently used in Genetics and Molecular Biology, I will develop into an independent researcher whose training will be an asset to the research community.

DESCRIPTION (Do not exceed space provided) The long-term goal of the proposed research is to gain greater insight into the processes by which cells obtain their shape. Although, the plant Arabidopsis thaliana is the subject of this research proposal, it is possible that the knowledge gained from understandingcell development in plants can be applied to cell development in animals. This is illustrated by one of the genes mentioned in this proposal, ZWI. The ZWI product, KCBP, was previously thought to be confined to the plant kingdom. Recently, a related protein, Kinesin-C, has been identified in animal cells (sea urchin) where it is thought to play a role in development. Therefore, genes that interact with KCBP in plants may have undiscovered counterparts in animal cells. Thus, what is learned from studying the genes that contribute to plant cell shapes may be applicable on a broader scope to humans. The immediate goals of the proposed research are to identify the FRC2 gene product, which is known to control trichome branch number in Arabidopsis, and test the predictions about its function in cell shape development. The specific objectives of the proposed research are: To clone the FRC2 gene and identify its product, to directly test the hypothesis that FRC2 is redundant to both ZWI and FRC4, to test the hypothesis that the FRC2 product interacts with the ZWI product, and to isolate suppressors and/or modifiers of the frc mutation.
