基因组数据正以前所未有的速度在公共数据库中积累。虽然目前主要由后生动物，植物，寄生，和picoeukaryotic类群的序列，表达序列标签（EST）和自由生活的藻类的完整基因组也慢慢出现。这丰富的信息提供了机会，澄清许多长期存在的问题，藻类和植物的进化，如贡献的质体内共生体的核基因组进化的比较基因组学和多基因遗传学的工具。一个特别强大的方法，自动分析基因组数据从多个类群被称为基因组学。系统基因组学是基因组学（研究基因和基因组的功能和结构）和分子遗传学（研究生物体及其基因和基因组之间的层次进化关系）的融合。利用遗传学来驱动比较基因组分析，促进了基因、基因家族和生物体进化历史的重建。在这里，我们调查了现有的基因组数据，介绍了藻类基因组管道，并回顾了藻类基因组数据的藻类基因组分析的一些初步结果。
Genomic data is accumulating in public database at an unprecedented rate. Although presently dominated by the sequences of metazoan, plant, parasitic, and picoeukaryotic taxa, both expressed sequence tag (EST) and complete genomes of free-living algae are also slowly appearing. This wealth of information offers the opportunity to clarify many long-standing issues in algal and plant evolution such as the contribution of the plastid endosymbiont to nuclear genome evolution using the tools of comparative genomics and multi-gene phylogenetics. A particularly powerful approach for the automated analysis of genome data from multiple taxa is termed phylogenomics. Phylogenomics is the convergence of genomics science (the study of the function and structure of genes and genomes) and molecular phylogenetics (the study of the hierarchical evolutionary relationships among organisms, their genes and genomes). The use of phylogenetics to drive comparative genome analyses has facilitated the reconstruction of the evolutionary history of genes, gene families, and organisms. Here we survey the available genome data, introduce phylogenomic pipelines, and review some initial results of phylogenomic analyses of algal genome data.
