Abstract

Isolated from intertidal sediment of the Yellow Sea, China, Bremerella sp. P1 putatively represents a novel species within the genus Bremerella of the family Pirellulaceae in the phylum Planctomycetota. The complete genome of strain P1 comprises a single circular chromosome with a size of 6,955,728 bp and a GC content of 55.26%. The genome contains 5772 protein-coding genes, 80 tRNA and 6 rRNA genes. A total of 147 CAZymes and 128 sulfatases have been identified from the genome of strain P1, indicating that the strain has the capability to degrade a wide range of polysaccharides. Moreover, a gene cluster related to bacterial microcompartments (BMCs) formation containing genes encoding the shell proteins and related enzymes to metabolize fucose or rhamnose is also found in the genome of strain P1. The genome of strain P1 represents the second complete one in the genus Bremerella, expanding the understanding of the physiological and metabolic characteristics, interspecies diversity, and ecological functions of the genus.

含有丰富多糖降解基因的平面菌P1的完整基因组序列

从中国黄海潮间带沉积物中分离出的 Bremerella sp.菌株 P1 的完整基因组由一条单环染色体组成，大小为 6,955,728 bp，GC 含量为 55.26%。基因组包含 5772 个蛋白质编码基因、80 个 tRNA 和 6 个 rRNA 基因。从菌株 P1 的基因组中共鉴定出 147 种 CAZymes 和 128 种硫酸酯酶，表明该菌株具有降解多种多糖的能力。此外，在菌株 P1 的基因组中还发现了一个与细菌微孔（BMC）形成有关的基因簇，其中含有编码壳蛋白和相关酶的基因，可代谢岩藻糖或鼠李糖。菌株 P1 的基因组是 Bremerella 属中第二个完整的基因组，拓展了对该属的生理和代谢特征、种间多样性和生态功能的认识。

期刊介绍： The journal publishes papers on all functional and evolutionary aspects of genes, chromatin, chromosomes and (meta)genomes of marine (and freshwater) organisms. It deals with new genome-enabled insights into the broader framework of environmental science. Topics within the scope of this journal include: • Population genomics and ecology • Evolutionary and developmental genomics • Comparative genomics • Metagenomics • Environmental genomics • Systems biology More specific topics include: geographic and phylogenomic characterization of aquatic organisms, metabolic capacities and pathways of organisms and communities, biogeochemical cycles, genomics and integrative approaches applied to microbial ecology including (meta)transcriptomics and (meta)proteomics, tracking of infectious diseases, environmental stress, global climate change and ecosystem modelling.
