Group Travel Grant for International Compositae Conference at the Royal Botanic Gardens, Kew, 24 July - 5 August 1994

9315506克劳福德向日葵属菊科或菊科向日葵是世界上最大的植物之一，约有20,000种，吸引了分类和进化生物学领域的大量科学家。自从1975年举行的上一次试图综合有关菊科的信息的国际会议以来，菊科一直是DNA分析的新分子方法以及许多关于形态、生活史、天然产物和民族植物学用途的其他研究的主题。俄亥俄州立大学的Daniel Crawford博士正在为几名美国与会者安排旅费，让他们参加在英国Kew的皇家植物园举行的关于菊科系统学和进化的国际会议。研究生和教研员有资格参加这次为期两周的会议，获得旅行补贴。近期的研究将集中在系统发育、基因组组织和变化、杂交、二倍体水平物种形成、天然产物化学、授粉和传播、生活史进化和民族植物学。会议预计将有来自美洲、欧洲、非洲、亚洲和澳大利亚许多国家的与会者。1975年举行的关于菊科的第一次国际会议导致出版了一本综合性卷，对向日葵植物科的系统学和进化研究产生了广泛和持久的影响。在Kew举行的第二次会议可能会取得类似的区别，特别是将重点介绍应用于这些植物的DNA和基因组组织的新分子技术的最新发现。

9315506 Crawford The sunflower family of plants, the Compositae or Asteraceae, is one of the largest in the world, with ca. 20,000 species, and has attracted a large proportion of scientists in taxonomic and evolutionary biology. Since the last international meeting where a synthesis of information was attempted on the family, in 1975, the Compositae have been the subjects of new molecular methods of DNA analysis and of numerous other studies on morphology, life histories, natural products, and ethnobotanical uses. Dr. Daniel Crawford of Ohio State University is coordinating travel grants for several U.S. participants to attend an international conference on the systematics and evolution of the Compositae, to be held at the Royal Botanic Gardens in Kew, England. Graduate students and faculty researchers are eligible for travel supplements to attend this two-week conference. Recent studies of phylogeny, genome organization and change, hybridization, diploid-level speciation, natural products chemistry, pollination and dispersal, life history evolution, and ethnobotany will be highlighted. The conference anticipates attendees from many countries in America, Europe, Africa, Asia, and Australia. The first international conference on the Compositae, held in 1975, led to publication of a synthesis volume with wide and lasting impact on studies of systematics and evolution of the sunflower family of plants. The second conference at Kew is likely to achieve similar distinction, and in particular will highlight recent findings from new molecular technologies applied to DNA and genome organization in these plants.
