SG: A revised classification of the flowering plant family Cleomaceae as a tool to understand drivers of diversification

该项目基于新的基因组数据和对开花植物物理特性的新评估，创建了一个重新组织的Cleomaceae植物家族分类。谱系之间关系的分类和相关假设将为家庭生理学、发育和基因组结构的研究提供关键和基础的框架。它还将有助于评估被认为属于该植物群的化石种子，从而改进对该家族谱系年龄的估计。这个项目所固有的知识的进步通过提供一个标准化的分类来组织我们对这些植物的理解，对社会做出了特别的贡献。这是园艺应用的基础知识，鉴定手册，保护研究，以及科学家和公众的许多其他应用。它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家族主要谱系的修正假设，并将完成正在进行的对这些谱系分类的修订。这个项目的一个具体目标是建立一个强大的系统发育假说之间的主要谱系之间的关系。该项目的目标是使用近乎完整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置于目前已知或新发现的谱系中。研究人员将对大约290个物种进行测序，约占该家族分类多样性的90%。该项目的第二个主要目标是利用系统发育来修订铁锤科的分类。一旦谱系被解决，就有必要识别可用于定义这些谱系并为组分配有效名称的结构特征。将研究来自种子和花粉的新的微形态特征，并对这些特征以及其他大形态特征进行评估，以确定谱系的潜力。目标是创建一个可预测的、实用的和稳健的Cleomaceae分类。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宝贵的框架。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

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.
