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.

这一美英合作研究奖将支持对英国的长期访问。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植物附属物形成模式的转变。他们将研究两个植物系统：(1)从硅烯到开花的转换；(2)豆瓣从根到冠的转换。拟议的工作将包括观察过渡期间尖端的生长，并进行实验，以确定阻止过渡或不产生任何影响的因果事件。Selker博士为这项合作带来了植物尖端细胞模式的生物物理表征方面的专业知识。此外，林登博士在硅烯和豆瓣菜系统方面的广泛工作，以及他在表征和操纵植物发育系统方面的创新实验方法，也补充了这一点。植物附属物，如叶、花瓣和雄蕊，是在枝尖形成图案的。研究人员不了解附肢是如何以特定的模式产生的，也不知道是什么导致这些模式发生变化。拟议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。
