0077979PruittLand plants are exposed to a variety of environmental fluctuations and challenges that require biological adaptations at the outermost surface or "skin" of the plant. A better understanding of the biology of this surface has significance not only for plant growth and development but also pertains directly to the effective use and application of man-made agents such as agricultural herbicides. Arabidopsis thaliana, a member of the mustard family, has been chosen as the model organism for these studies. Significant progress toward elucidating biological features of the plant surface have already been made using this plant. The research described here will expand upon this body of work. The biology of the plant surface as it pertains specifically to its biochemical and molecular properties will be studied using a collection of plants with altered surface properties. Using these plants it will be possible to identify additional components involved in the building and maintenance of the plant outer "skin". By identifying the constituents that make up this complex outer layer and developing a guide for how this surface is put together, a better understanding of how plants mediate responses and adaptations to their environment will be achieved. Insight into these fundamental processes may possibly have far reaching economic consequences by ultimately diminishing the cost of weed management and the impact of weed-based losses in crop productivity. A reduction in herbicide use would have the added benefit of decreasing the environmental impact of modern crop management practices.

0077979PruittLand植物暴露于各种环境波动和挑战，需要在植物的最外表面或“皮肤”处进行生物适应。 更好地了解这一表面的生物学不仅对植物生长和发育具有重要意义，而且直接涉及到有效使用和应用人造试剂，如农业除草剂。 拟南芥，芥菜家族的一员，已被选为这些研究的模式生物。 利用这种植物已经在阐明植物表面的生物学特征方面取得了重大进展。 这里描述的研究将扩展这一工作的主体。 植物表面的生物学，因为它特别涉及到其生物化学和分子特性将使用一系列的植物与改变的表面特性进行研究。 使用这些工厂，将有可能确定参与工厂外部“皮肤”的构建和维护的其他组件。 通过识别构成这个复杂外层的成分并制定如何将这个表面组合在一起的指南，将更好地了解植物如何介导对其环境的反应和适应。 深入了解这些基本过程可能会产生深远的经济后果，最终减少杂草管理的成本和作物生产力的杂草损失的影响。 减少除草剂的使用将带来额外的好处，即减少现代作物管理做法对环境的影响。
