Dissertation Research: Molecular Phylogenetic Analysis and Pigment Distribution and Relationships in the Caryophyllales

MABRY该奖项将为德克萨斯大学奥斯汀分校的一名学生的博士论文研究提供支持。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。该研究将通过将不同科的信息叠加到该目植物科的枝状图或关系图上，来调查石竹目植物中红紫色色素类型（花青素和甜菜素）的起源。这个枝状图将从叶绿体基因组的两个区域（rbcL和ndhF）的分子序列数据中得出，并将允许测试关于相对独特的植物色素类甜菜素起源的假设。这个奖项将有助于培养一名年轻的植物系统学家在现代分子系统方法方面的研究。该研究将有助于了解石竹科不同植物目间的关系，并为甜菜素色素的起源提供信息。这些花色素可能构成吸引传粉者的重要信号系统，了解它们的起源可能对传粉生物学的研究很重要。＊＊＊

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. ***
