U.S.-U.K. Cooperative Research: Pattern Transitions at the Shoot Apex of Plants

这项美英合作研究奖将支持对英国进行长期访问。俄勒冈大学的珍妮·塞尔克博士和爱丁堡大学的罗伯特·林登博士将共同研究发育中的植物附属物形成模式的转变。他们将研究两个植物系统：(1)沉默植物过渡到开花；(2)豆瓣菜根茎转化。拟议的工作将包括在过渡期间观察顶点的生长，并进行旨在确定阻止过渡或不产生任何影响的因果事件的实验。Selker博士为这次合作带来了植物尖端细胞模式的生物物理特征方面的专业知识。这是由林登博士在Silene和豆瓣菜系统方面的广泛工作以及他的创新实验方法来表征和操纵植物发育系统的补充。植物的附属物，如叶、花瓣和雄蕊，在茎尖以一定的模式产生。研究人员不知道附属物是如何以特定的模式产生的，也不知道是什么导致了这些模式的变化。提出的研究将产生关于过渡过程和模式形成的有价值的知识和相关性。

This award for U.S.-U.K. cooperative research will support a long- term visit to the United Kingdom. Dr. Jeanne Selker of the University of Oregon and Dr. Robert Lyndon of the University of Edinburgh will jointly study the transition in patterns of appendage formation in developing plants. They will study two plant systems: (1) Silene transition to flowering; and (2) watercress root-to-shoot conversion. The proposed work will involve observations of the growth of apices during the transition period and experiments aimed at identifying the causal events which either prevent transition or produce no effect whatsoever. Dr. Selker brings to this collaboration expertise in the biophysical characterization of cell patterns in plant apices. This is complemented by Dr. Lyndon's extensive work on the Silene and watercress systems and his innovative experimental approaches to characterizing and manipulating plant developing systems. Plant appendages, such as leaves, petals and stamens, are produced at the shoot apex in a pattern. Researchers do not understand how appendages are produced in a specific pattern or what causes these patterns to change. The proposed research will yield valuable knowledge and correlations about the transition processes and pattern formations.
