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

应用分类学方法对棕榈科Caryota属的生物系统学研究 形态学、解剖学和DNA水平分析。 该属是热带森林树木的单系群， 经济、进化和生态重要性。 由于 许多形态特征的变异性， 分类学，核动物门内的种划分和系统发育 类核植物属之间的关系还没有得到很好的解决。 数据集，独立于几行查询 包括描述性形态学和解剖学、几何学 形态计量学、叶绿体和核基因组限制 核酸内切酶位点作图，和孢粉学将受到一个 各种系统发育分析，努力建立一个 可靠的分类学和专着的属，检查 内部系统发育关系和可变形态 棕榈树中的特征，研究分子进化的模式 在类核植物的手掌，并探讨模式， 物种形成在属内表达。

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.
