Travel to the Third International Symposium on Grass Systematics and Evolution, Sydney, Australia, 1998

克拉克DEB-9806584牧草是极其重要的经济和生态植物。这个科不仅包括世界上主要的农作物，如小麦、水稻、玉米、大麦、甘蔗和竹子，而且几乎所有陆地栖息地都有这种草。了解不同草类群之间的进化关系为许多领域的研究提供了基本框架，包括生物多样性、遗传学、发育、分子生物学和作物改良。草类系统发育工作组(GPWG)由12名草类分类学家组成，成立于1996年，目的是分析一些不同的、最近可用的数据集，其中包含有关草类之间进化关系的信息。这项分析的结果，以及根据它们的进化关系对草科进行的最新分类，将在1998年9月在澳大利亚悉尼举行的第三届国际草类研讨会上提交，该研讨会将与第二届单子叶植物比较生物学国际会议一起举行。提供的资金将支持GPWG的10名美国成员参加这次会议并介绍和讨论这一合作努力的结果，其中包括初级调查人员和一名研究生。

Clark DEB-9806584 The grasses are economically and ecologically extremely important plants. Not only does this family include major world crops such as wheat, rice, maize, barley, sugar cane, and bamboo, but the grasses also occur in virtually all terrestrial habitats. An understanding of the evolutionary relationships among the different groups of grasses provides a fundamental framework for research in many fields, including biodiversity, genetics, development, molecular biology, and crop improvement. The Grass Phylogeny Working Group (GPWG), consisting of 12 grass taxonomists, was formed in 1996 to analyze a number of different, recently available data sets that contain information about evolutionary relationships among grasses. The results of this analysis, along with an updated classification of the grass family based on their evolutionary relationships, will be presented at the Third International Grass Symposium to be held in Sydney, Australia, in September, 1998 in conjunction with the Second International Conference on the Comparative Biology of the Monocotyledons. The funding provided will support travel by ten of the U. S. members of the GPWG, including junior investigators and a graduate student, to attend this meeting and to present and discuss the results of this collaborative effort.
