Dinoflagellates are a common and important group of single- celled organisms. They are both free-living and symbiotic with a diversity of other organisms. The symbiotic forms have evolved several distinct functional relationships within their hosts, and this has led to differences of opinion concerning their evolutionary relationships, and their origin (or origins) from other single-celled eucaryotic groups. Drs. Clifford Brunk and David Chapman propose to obtain RNA sequence data from the appropriate species, providing a powerful data set from which to infer evolutionary relationships. The evolutionary tree based on the new sequence data will be compared with the trees based on biochemical and morphological data. The proposed research will have wide impact beyond the community of dinoflagellate specialists. This project focuses on some of the earliest branches in the tree of life, and the results will provide microbiologists, microbial ecologists, and marine biologists with a framework for studying diverse phenomena. The results will also break new ground in the use of molecular data from micro-organisms, and will provide new insight into the evolution of symbiosis.

甲藻是一种常见而重要的单- 细胞有机体 它们都是自由生活的， 其他生物的多样性。 共生体已经进化出 在其宿主中存在几种不同的功能关系， 这导致了对他们的意见分歧。 进化关系，以及它们的起源（或起源） 其他单细胞真核生物群。 克利福德·布伦克博士和 大卫查普曼建议从基因组中获得RNA序列数据， 适当的物种，提供了一个强大的数据集， 推断进化关系。 进化树基于 新的序列数据将与基于以下的树进行比较： 生物化学和形态学数据。 拟议的研究将产生广泛的影响， 甲藻专家的社区。 该项目的重点是 生命之树上最早的一些树枝， 结果将提供微生物学家，微生物生态学家， 海洋生物学家的研究框架， 现象。 其结果也将在使用方面开辟新天地 微生物的分子数据，并将提供新的见解 进入共生的进化。
