We report the draft genome sequence of the model moss Physcomitrella patens and compare its features with those of flowering plants, from which it is separated by more than 400 million years, and unicellular aquatic algae. This comparison reveals genomic changes concomitant with the evolutionary movement to land, including a general increase in gene family complexity; loss of genes associated with aquatic environments (e.g., flagellar arms); acquisition of genes for tolerating terrestrial stresses (e.g., variation in temperature and water availability); and the development of the auxin and abscisic acid signaling pathways for coordinating multicellular growth and dehydration response. The Physcomitrella genome provides a resource for phylogenetic inferences about gene function and for experimental analysis of plant processes through this plant's unique facility for reverse genetics.
我们报告了模式苔藓小立碗藓的基因组序列草图，并将其特征与开花植物以及单细胞水生藻类进行了比较。开花植物与小立碗藓在进化上相隔超过4亿年。这种比较揭示了与向陆地进化相关的基因组变化，包括基因家族复杂性普遍增加；与水生环境相关的基因（如鞭毛臂）丢失；获得耐受陆地胁迫的基因（如温度和水分可利用性的变化）；以及生长素和脱落酸信号通路的发展，用于协调多细胞生长和脱水反应。小立碗藓基因组为通过该植物独特的反向遗传学工具进行基因功能的系统发育推断和植物过程的实验分析提供了资源。
