我们报道了银杉属植物的完整细胞器基因组序列。菌株MX-AZ01，一种从墨西哥地热田分离的嗜酸绿色微藻。这种真核生物有非凡的能力在一个特定的浅水湖中繁衍生息，湖底有涌现的温泉，极低的pH值和有毒的重金属浓度。木霉Trebuxiophyceae sp.MX-AZ01代表了生活在如此恶劣环境中的为数不多的光合作用真核生物之一。银耳属植物细胞器基因组研究。MX-AZ01令人惊叹。叶绿体基因组序列目前呈现出树芽植物中最高的G+C含量。线粒体基因组序列是迄今为止报道的绿藻类中最大的线粒体基因组序列。本文对基因组序列的分析提供了对海藻和绿藻细胞器基因组进化的洞察。
We report the complete organelle genome sequences of Trebouxiophyceae sp. strain MX-AZ01, an acidophilic green microalga isolated from a geothermal field in Mexico. This eukaryote has the remarkable ability to thrive in a particular shallow lake with emerging hot springs at the bottom, extremely low pH, and toxic heavy metal concentrations. Trebouxiophyceae sp. MX-AZ01 represents one of few described photosynthetic eukaryotes living in such a hostile environment. The organelle genomes of Trebouxiophyceae sp. MX-AZ01 are remarkable. The plastid genome sequence currently presents the highest G + C content for a trebouxiophyte. The mitochondrial genome sequence is the largest reported to date for the Trebouxiophyceae class of green algae. The analysis of the genome sequences presented here provides insight into the evolution of organelle genomes of trebouxiophytes and green algae.
