摘要

咸淡蓝藻基因组序列是相对罕见的。本文报道了从荷兰Schiermonnikoog岛北海海岸微生物垫中分离到的螺旋藻sp. CCY15215、leptolyynbya sp. CCY15150和Halomicronema sp. CCY15110的5.5 Mbp、5.8 Mbp和6.1 Mbp基因组草图。大规模系统基因组学分析表明，螺旋藻sp. CCY15215是一种大细胞直径的蓝藻，而leppolyynbya sp. CCY15150和Halomicronema sp. CCY15110是首次报道的属于LPP分支的半咸水基因组，该分支主要由leppolyynbya, Plectonema和Phormidium spp组成。进一步的基因组挖掘揭示了所有新基因组都包含ggpS和ggpP，这些基因负责合成葡萄糖-甘油(GG)。一种在适度耐盐蓝藻中发现的相容溶质。

Draft genome sequences of three filamentous cyanobacteria isolated from brackish habitats.

Brackish cyanobacterial genome sequences are relatively rare. Here, we report the 5.5 Mbp, 5.8 Mbp and 6.1 Mbp draft genomes of Spirulina sp. CCY15215, Leptolyngbya sp. CCY15150 and Halomicronema sp. CCY15110 isolated from coastal microbial mats on the North Sea beach of the island of Schiermonnikoog in the Netherlands. Large scale phylogenomic analyses reveal that Spirulina sp. CCY15215 is a large cell diameter cyanobacterium, whereas Leptolyngbya sp. CCY15150 and Halomicronema sp. CCY15110 are the first reported brackish genomes belonging to the LPP clade consisting primarily of Leptolyngbya, Plectonema and Phormidium spp. Further genome mining divulges that all new draft genomes contain, ggpS and ggpP , the genes responsible for synthesising glucosylglycerol (GG), a compatible solute found in moderately salt-tolerant cyanobacteria.
