Drought stress is ubiquitous and is an important selective agent in the evolution of plant growth, development, and physiology. Drought stress is also a major limiting factor to crop productivity worldwide. Many plant species vary among genetic lines in their ability to cope with drought and this variation provides a unique resource for exploring gene function. This 2010 project will identify genes and physiological networks associated with drought resistance in Arabidopsis thaliana using genome-wide molecular techniques and natural variation among accessions from different locations. Drought-induced gene expression and physiological differences among accessions with extreme high and low water use efficiency will be characterized and genes involved will be mapped to genomic positions. In addition, new resources will be developed for quantitative genetic studies in Arabidopsis, including a mapping population and a series of genetic lines capturing genomic regions from physiologically diverse accessions. Results from this project will be useful for application to crop improvement and to understanding evolution of drought resistance in plants. The project will provide training for postdocs and students in molecular genetics, evolutionary biology, physiology, and bioinformatics - skills necessary for the next generation of successful genomic scientists. Undergraduate and community college students will gain research experience and career exploration and preparation. All plant materials and associated genotypic data will be made available using The Arabidopsis Information Resource infrastructure (http://www.arabidopsis.org). Project progress will be available at the project website (https://webspace.utexas.edu/tjuenger/www/2010.htm). Microarray data generated through the project will be submitted to AtGenExpress (http://web.uni-frankfurt.de/fb15/botanik/mcb/AFGN/atgenex.htm).

干旱胁迫普遍存在，是植物生长、发育和生理进化中的重要选择因子。 干旱胁迫也是全世界作物产量的一个主要限制因素。许多植物物种在遗传系之间科普干旱的能力存在差异，这种变异为探索基因功能提供了独特的资源。 这个2010年的项目将使用全基因组分子技术和来自不同地点的种质之间的自然变异来鉴定与拟南芥抗旱性相关的基因和生理网络。干旱诱导的基因表达和极端高和低水分利用效率的加入之间的生理差异的特点和相关基因将被定位到基因组位置。 此外，还将开发新的资源用于拟南芥的定量遗传研究，包括一个作图群体和一系列从生理上不同的种质中捕获基因组区域的遗传品系。 本计画之研究结果将有助于作物改良及了解植物抗旱性之演化。该项目将为博士后和学生提供分子遗传学，进化生物学，生理学和生物信息学方面的培训-下一代成功的基因组科学家所必需的技能。本科和社区学院的学生将获得研究经验和职业探索和准备。 所有的植物材料和相关的基因型数据将使用拟南芥信息资源基础设施（http：//www.example.com）提供。www.arabidopsis.org 项目进展情况将在项目网站（https：//webspace.utexas.edu/tjuenger/www/2010.htm）上公布。 通过该项目生成的微阵列数据将提交给AtGenExpress（http：//web.uni-frankfurt.de/fb15/botanik/mcb/AFGN/atgenex.htm）。
