9520821 MABRY This award will contribute support to the doctoral dissertation research of a student at the University of Texas, Austin. The award will provide funds for laboratory supplies for molecular sequencing and for travel to collect plants within the United States. The study will investigate the origins of red-violet pigment types (anthocyanins and betalains) in the plant order Caryophyllales by superimposing this information for different families onto a cladogram or diagram of relationships of families in this order of plants. This cladogram will be derived from molecular sequence data for two regions of the chloroplast genome (rbcL and ndhF) and will allow testing of hypotheses about origins of the relatively unique plant pigment class of betalains. %%% This award will contribute to the research training of a young plant systematist in modern molecular systematic methods. The study should contribute knowledge about relationships in the diverse plant order Caryophyllales and provide information about the origins of betalain pigments. These floral pigments may constitute important signaling systems to attract pollinators and knowledge about their origins may prove important to studies of pollination biology. ***

9520821 MABRY这个奖项将有助于支持在得克萨斯大学奥斯汀分校的学生的博士论文研究。 该奖项将为分子测序的实验室用品和在美国境内收集植物的旅行提供资金。 这项研究将调查红紫色色素类型（花青素和甜菜色素）的起源在植物订单康乃馨，通过叠加这些信息为不同的家庭到一个分支图或图的家庭关系，在这个顺序的植物。 该分支图将来自叶绿体基因组的两个区域（rbcL和ndhF）的分子序列数据，并将允许测试相对独特的植物色素类甜菜色素的起源的假设。 该奖项将有助于在现代分子系统学方法的年轻植物系统学家的研究培训。 这项研究将有助于了解不同植物的关系，并提供有关甜菜色素的起源信息。 这些花色素可能构成重要的信号系统，以吸引传粉者和知识，他们的起源可能证明是重要的授粉生物学研究。 ***
