This study will examine the potential that an array of molecules with inducing properties involved in bacterial infection of plants exists, and seeks to determine the chemistry, specificity, and roles of these molecules in plant-bacterial interactions. The focus will be identification of signal compounds, the physiological roles of inducers in the plant that produces them, and to a limited extent, the receptors for these inducers. It is expected that such studies at detailed chemical and biological levels will lead to a fuller understanding of events connected with establishment of, or resistance to, bacterial infections in a variety of plants, and be of value in broadening the spectrum of plants that can be transformed by bacteria such as those in the genus Agrobacterium. How plants, and the bacteria able to infect them, communicate with each other at the molecular level to determine susceptibility or resistance to infection is a prime focus of this study. A fuller understanding of these events may lead to the ability to transform plant systems that are now recalcitrant to such genetic change. //

这项研究将研究一系列分子 具有与植物细菌感染有关的诱导特性 存在，并试图确定化学，特异性， 这些分子在植物-细菌相互作用中的作用。 的 重点将是识别信号化合物，生理 诱导物在产生它们的植物中的作用，以及有限的 在一定程度上，这些诱导剂的受体。 预计这样 详细的化学和生物水平的研究将导致 更充分地了解与建立或 在各种植物中对细菌感染的抗性， 在扩大植物的光谱，可以是有价值的 由细菌如农杆菌属中的那些转化。 植物和能够感染它们的细菌是如何与 在分子水平上相互检测以确定易感性， 对感染的抵抗力是本研究的主要焦点。 更全面 对这些事件的理解可能会使我们有能力 现在对这种遗传变化不敏感的植物系统。 //
