The Streptophyta include unicellular and multicellular charophyte green algae and land plants. Colonization of the terrestrial habitat by land plants is a major evolutionary event that has transformed the planet. So far, lack of genome information on unicellular charophyte algae hinders the understanding of the origin and the evolution from unicellular to multicellular life in Streptophyta. This work reports the high-quality reference genome and transcriptome of Mesostigma viride, a single-celled charophyte alga with a position at the base of Streptophyta. There are abundant segmental duplications and transposable elements in M. viride, which contribute to a relatively large genome with high gene content compared to other algae and early diverging land plants. This work identifies the origin of genetic tools that multicellular Streptophyta have inherited and key genetic innovations required for the evolution of land plants from unicellular aquatic ancestors. The findings shed light on the age-old questions of the evolution of multicellularity and the origin of land plants.

Mesostigma viride 基因组和转录组为链藻门的起源和进化提供了见解。
链藻门包括单细胞和多细胞轮藻绿藻和陆地植物。陆地植物对陆地栖息地的殖民是改变地球的重大进化事件。迄今为止,单细胞轮藻的基因组信息的缺乏阻碍了对链藻门起源和从单细胞到多细胞生命进化的理解。这项工作报告了 Mesostigma viride 的高质量参考基因组和转录组,Mesostigma viride 是一种单细胞轮藻,位于链藻门的基部。 M. viride 中存在丰富的片段重复和转座元件,与其他藻类和早期分化的陆地植物相比,其基因组相对较大,基因含量较高。这项工作确定了多细胞链球菌继承的遗传工具的起源,以及从单细胞水生祖先进化出陆地植物所需的关键遗传创新。这些发现揭示了多细胞进化和陆地植物起源等古老问题。
