A systematic survey of DNA variation in the genus Vernonia (Vernonieae:Asteraceae) will be undertaken using comparative restriction site mapping and DNA sequencing in chloroplast DNA. Restriction site maps will provide the first direct genetic evidence for relationships between New and Old World taxa within the large tribe Vernonieae, and make it possible to construct a genetically based phylogeny. No such phylogeny current exists. Phylogenetic relationships based on cpDNA structure will contribute to an understanding of biogeographical relationships with Vernonia and the Vernonieae, and would be of value in understanding the processes of evolution which have caused the Asteraceae to diverge into distinct tribes. The Asteraceae is the largest family of flowering plants with ca. 20,000 species worldwide, an understanding of evolutionary processes within this family has significance to our overall understanding of evolutionary processes responsible for past and present floral diversity. The interactive phase of this project involves a combination of professional activities as a visiting teacher and researcher in Ecology and Evolutionary Biology and participation in programs in Women's Studies and the Women's Center at University of Connecticut. A seminar program jointly sponsored by Ecology and Evolution and the Women's Center to bring visiting women scientists to campus will be used to integrate coursework in Molecular Systematics and Women in Science courses. This project furthers VPW program objectives which are (1) to provide opportunities for women to advance their careers in engineering and in the disciplines of science supported by NSF and (2) to encourage women to pursue careers in science and engineering by providing greater visibility for women scientists and engineers employed in industry, government, and academic institutions. By encouraging the participation of women in science, it is a valuable investment in the Nation's future scientific vitality.

斑鸠菊属植物DNA变异的系统研究 （斑鸠菊族：菊科）将进行比较 叶绿体DNA中的限制性位点作图和DNA测序。 限制性酶切位点图谱将提供第一个直接的遗传 新大陆和旧大陆分类群之间关系的证据 大部落斑鸠菊，并使其有可能建立一个 基于基因的遗传学 不存在这样的超验电流。 基于cpDNA结构的系统发育关系将 有助于理解地理关系 与斑鸠菊和斑鸠菊科，并将在价值， 理解进化的过程， 菊科分化成不同的族。 菊科是 开花植物中最大的科，约有。2万种 在世界范围内，对这一过程中的进化过程的理解 家庭对于我们全面理解 负责过去和现在花的进化过程 多样性 这个项目的互动阶段包括一个组合 作为访问教师和研究人员的专业活动 在生态学和进化生物学和参与方案 在妇女研究和妇女中心在大学 康涅狄格 由生态学和 进化和妇女中心，使来访的妇女 科学家到校园将被用来整合课程， 分子系统学和妇女在科学课程。 本项目进一步促进了VPW计划的目标，即（1） 为妇女提供机会， 工程和科学的学科由NSF支持 （2）鼓励妇女从事科学事业， 通过提高女科学家的知名度， 以及受雇于工业、政府和学术界的工程师 机构职能体系 通过鼓励妇女参与 这是对国家未来的宝贵投资。 科学生命力
