The Green Algae Tree of Life (GRAToL) is a project involving the collaboration of five institutions to understand the evolutionary relationships of all of the major groups of green algae, a diverse group of more than 14,000 photosynthetic species worldwide. Green algae are abundant and play important roles in a wide variety of terrestrial and aquatic habitats, including deserts, extremely salty ponds, and coral reefs, and several species are symbiotic partners with lichens and animals. Thus, green algae are important primary producers in most ecosystems. Green algae are diverse in form - from microscopic single cells to large seaweeds - and function as important primary producers in most ecosystems. The project will employ DNA sequence data to assemble a tree of life reflecting the evolutionary history of the group. This tree will be critical for an improved classification of known species of algae as well as species that are yet to be discovered. The project will facilitate further studies of green algae genomics and evolution.The project will train 3-4 postdoctoral researchers, several graduate students, and numerous undergraduate students in basic research on algae and genomics. New analytical tools will be developed for use by the broader scientific community. A public exhibit on the GRAToL will be produced, along with a web site containing images and other information on evolution of the group that will be of interest to educators and the general public.

绿藻生命之树（GRAToL）是一个涉及五个机构合作的项目，旨在了解所有主要绿藻群体的进化关系，全球有超过14,000种光合作用物种。绿藻丰富，在各种陆地和水生栖息地中发挥重要作用，包括沙漠、极咸池塘和珊瑚礁，其中一些物种与地衣和动物是共生伙伴。因此，绿藻是大多数生态系统中重要的初级生产者。绿藻的形态多种多样——从微小的单细胞到大型海藻——在大多数生态系统中都是重要的初级生产者。该项目将使用DNA序列数据来组装反映该群体进化史的生命树。这棵树对于改进已知种类的藻类以及尚未发现的物种的分类至关重要。该项目将促进绿藻基因组学和进化的进一步研究。本项目将培养3-4名博士后、数名研究生和多名本科生从事藻类和基因组学基础研究。将开发新的分析工具，供更广泛的科学界使用。将制作一个关于GRAToL的公开展览，同时还将制作一个网站，其中载有教育工作者和一般公众感兴趣的关于该群体演变的图像和其他信息。
