Dissertation Research: Molecular and Morphological Analysis of Caryota (Palmae)

利用形态学、解剖学和DNA水平分析对棕榈属植物进行生物系统研究。该属是热带森林树木的单系群，具有经济、进化和生态重要性。由于以往分类中使用的许多形态特征的可变性，核心科内的种划分和核心科属之间的系统发育关系没有得到很好的解决。从描述形态学和解剖学、几何形态计量学、叶绿体和核基因组限制性内切酶位点定位以及孢粉学等几方面独立获得的数据集将进行各种系统发育分析，以建立可靠的属分类和专著。研究棕榈树内部的系统发育关系和可变的形态特征，研究类核仁棕榈树的分子进化模式，探索生物地理学和物种形成的模式，在属中表达。

A biosystematic study of the genus Caryota (Palmae) using morphological, anatomical, and DNA level analyses is proposed. The genus is a monophyletic group of tropical forest trees with economic, evolutionary, and ecological importance. Due to the variability of many morphological characters used in previous taxonomies, species delimitions within Caryota and phylogenetic relationships among the caryotoid genera are not well resolved. Datasets, derived independently from several lines of inquire including descriptive morphology and anatomy, geometric morphometry, chloroplast and nuclear genome restriction endonuclease site mapping, and palynology will be subjected to a variety of phylogenetic analyses in an effort to establish a reliable taxonomy and monograph for the genus, examine phylogenetic relationships within and variable morphological characters within palms, examine patterns of molecular evolution in the caryotoid palms, and explore patterns of biogeography and speciation as expressed within the genus.
