AToL for Gymnosperms: Resolving the Phylogeny of Seed PlantsAn award is made to Sarah Mathews (Lead PI), Jianhua Li (Co-PI), Harvard University; Reed S. Beaman (PI), Nico Cellinese (Co-PI), Yale University; Christopher S. Campbell (PI), University of Maine; Richard C. Cronn (Collaborator), USDA Forest Service; Sean W. Graham (Co-PI), University of British Columbia; Stefanie M. Ickert-Bond (PI), University of Alaska; Dean G. Kelch (PI), University of California-Berkeley and California State Herbarium; Aaron I. Liston (PI), Oregon State University; Linda A. Raubeson (PI), Central Washington University; Gar W. Rothwell (PI), Gene Mapes (Co-PI), Ohio University; Andrea E. Schwarzbach (PI), University of Texas-Brownsville; Dennis W. Stevenson (PI), New York Botanical Garden; Ruth A. Stockey (Co-PI), University of Alberta to construct sequence-based phylogenetic hypotheses for all living gymnosperms and for seed plants overall, and morphology-based hypotheses to include ALL living species of gymnosperms (conifers, cycads, Gingko, and Gnetales) including examples from the fossil record, along with exemplar angiosperms (flowering plants). Nuclear, plastid and mitochondrial sequences will be utilized in the analysis along with the morphological characters to allow the rich record of fossil gymnosperms to be included. All of the data (molecular, morphological, voucher, etc.) will be submitted to standardized and accessible databases through an enhanced version of the web-based informatics tool TOLKIN (Tree Of Life Knowledge and Information Network, www.tolkin.org). The evolution of the seed marks one of the most important innovations in the history of land plants and led to greater mating control and to enhanced survival and dispersal capabilities. Seed bearing plants dominate the landscape; today, forests and grasslands are among our most important resources. Understanding the origin(s) of seeds is basic to understanding seed plant phylogeny. Obtaining the needed phylogenetic framework is not a trivial undertaking and the multi-faceted approach is designed to address the inherent complexity of the problem, incorporating approaches not considered by all projects (e.g., including all gymnosperms, serious attention to the fossil data). While phylogenetic inference will be the main focus of the project, data will bear significantly on the understanding of historic patterns of biotic change at the global level, and will provide insight into the origins of many important plant traits, including those that are the basis of breeding programs in horticulture and forestry. In addition to training students, workshops for K-12 teachers will be held at several botanic gardens.

Stockey）（CO-PI），艾伯塔省大学，为所有活体育体和种子植物的总体以及基于形态学的假设构建基于序列的系统发育假设，包括所有裸子植物的活物种（针叶树，寿命，寿命，寿命，金氏，gingko和gnetales）以及植物包括expers expers expers and expers and expers（包括expers expers）。分析中将利用核，质体和线粒体序列以及形态学特征，以允许包括化石体育体的丰富记录。 所有数据（分子，形态，代金券等）将通过基于Web的Informatics工具Tolkin的增强版本（生命知识和信息网络，www.tolkin.org）提交给标准化且可访问的数据库。种子的演变标志着土地植物历史上最重要的创新之一，并导致了更大的交配控制，并增强了生存和分散能力。 种子轴承植物主导着景观；如今，森林和草原是我们最重要的资源之一。 了解种子的起源是理解种子植物系统发育的基础。 获得所需的系统发育框架并不是一项微不足道的事业，多方面的方法旨在解决问题的固有复杂性，并结合了所有项目所未考虑的方法（例如，包括所有裸露的体育典礼，对化石数据的认真关注）。 虽然系统发育推断将是该项目的主要重点，但数据将大大依赖于对全球生物变化的历史模式的理解，并将洞悉许多重要的植物特征的起源，包括那些是园艺和林业中繁殖计划的基础。除了培训学生外，K-12老师的讲习班还将在几个植物园举行。
