项目摘要

This project creates a reorganized classification of the flowering plant family Cleomaceae based on new genomic data and a new assessment of physical characteristics of the plants. The classification and associated hypotheses of relationships among lineages will provide a critical and foundational framework for studies of physiology, development, and genome structure in the family. It will also contribute to the evaluation of fossil seeds that are thought to belong to this plant group, enabling improved estimates of the ages of lineages in the family. The advancement of knowledge inherent to this project particularly contributes to society by providing a standardized classification for organizing our understanding of these plants. This is foundational knowledge for horticultural use, identification manuals, conservation studies, and many other applications by scientists and the general public. It will also provide training for one graduate student researcher at Washington State University.This project uses DNA sequence data and morphology to create revised hypotheses of the major lineages in the family and will complete the ongoing revision of the classification of these lineages. One specific goal of this project is to create a robust phylogenetic hypothesis of the relationships among major lineages of Cleomaceae. The goal of the project is to use near-complete species-level sampling and new genomic data to place all or nearly all species in currently recognized or newly identified lineages. Researchers will sequence about 290 species, or ~90% of the taxonomic diversity of the family. The second major goal of the project is to use the phylogeny to revise the classification of Cleomaceae. Once lineages are resolved, it will be necessary to identify structural characteristics that can be used to define these lineages and assign valid names to the groups. New micromorphological characters from seeds and pollen will be investigated, and these as well as additional macromorphological characters will be evaluated for potential to define lineages. The goal is to create a classification of Cleomaceae that is predictive, practical, and robust. This revised classification will provide an invaluable framework for comparative studies of physiology, floral development, and genome structure.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
该项目根据新的基因组数据和对植物物理特征的新评估,对开花植物科进行了重新分类。谱系之间关系的分类和相关假设将为该家族的生理、发育和基因组结构的研究提供一个关键的和基础的框架。它还将有助于评估被认为属于该植物组的化石种子,从而改进对该家族谱系年龄的估计。这个项目固有的知识的进步特别有助于社会,因为它为我们组织对这些植物的了解提供了一个标准化的分类。这是科学家和公众关于园艺应用、鉴定手册、保护研究和许多其他应用的基础知识。该项目还将为华盛顿州立大学的一名研究生研究员提供培训。该项目使用DNA序列数据和形态学来创建对该家族主要血统的修订假说,并将完成正在进行的这些血统分类的修订。这个项目的一个具体目标是建立一个关于蜡梅科主要谱系之间关系的强有力的系统发育假说。该项目的目标是使用接近完成的物种水平采样和新的基因组数据,将所有或几乎所有物种归入目前公认的或新确定的谱系。研究人员将对大约290种物种进行测序,约占该科分类多样性的90%。该项目的第二个主要目标是利用系统发育学来修订蜡梅科的分类。一旦血统得到解决,就有必要确定可用于定义这些血统的结构特征,并为群体分配有效的名称。将研究种子和花粉的新微形态特征,并对这些特征以及其他大形态特征进行评估,以确定谱系的可能性。我们的目标是创建一个具有预测性、实用性和健壮性的蜡梅科分类。这一修订后的分类将为生理学、花发育和基因组结构的比较研究提供一个宝贵的框架。这一奖项反映了NSF的法定使命,并通过使用基金会的智力优势和更广泛的影响审查标准进行评估,被认为值得支持。
