Labrenzia sp. are important components of marine ecology which play a key role in biochemical cycling. In this study, we isolated the Labrenzia sp. PO1 strain capable of forming biofilm, from the A. sanguinea culture. Growth analysis revealed that strain reached a logarithmic growth period at 24 hours. The whole genome of 6.21813 Mb of Labrezia sp. PO1 was sequenced and assembled into 15 scaffolds and 16 contigs, each with minimum and maximum lengths of 644 and 1,744,114 Mb. A total of 3,566 genes were classified into five pathways and 31 pathway groups. Of them, 521 genes encoded biofilm formation proteins, quorum sensing (QS) proteins, and ABC transporters. Gene Ontology annotation identified 49,272 genes that were involved in biological processes (33,425 genes), cellular components (7,031genes), and molecular function (7,816 genes). We recognised genes involved in bacterial quorum sensing, attachment, motility, and chemotaxis to investigate bacteria's ability to interact with the diatom phycosphere. As revealed by KEGG pathway analysis, several genes encoding ABC transporters exhibited a significant role during the growth and development of Labrenzia sp. PO1, indicating that ABC transporters may be involved in signalling pathways that enhance growth and biofilm formation.

Labrenzia sp。是海洋生态的重要组成部分，在生化循环中起着关键作用。在这项研究中，我们分离了Labrenzia sp.。PO1菌株能够从A.sanguinea 培养物中形成生物膜。生长分析表明，菌株在24小时达到对数生长期。的6.21813 MB的全基因组 Labrezia sp。PO1测序并组装成15个支架和16个重叠群，每个最小和最大长度分别为644和1,744,114 Mb。总共3,566个基因被分为五个途径和31个途径组。其中，有521个基因编码生物膜形成蛋白，群体感应（QS）蛋白和ABC转运蛋白。基因本体论注释识别了49,272个基因，这些基因参与了生物过程（33,425个基因），细胞成分（7,031个基​​因）和分子功能（7,816个基因）。我们识别了与细菌群体感应，附着，运动和趋化性有关的基因，以研究细菌与硅藻藻圈相互作用的能力。正如KEGG通路分析所揭示的，编码ABC转运蛋白的几个基因在Labrenzia的生长和发育过程中发挥了重要作用。sp。PO1，表明ABC转运蛋白可能参与增强生长和生物膜形成的信号传导途径。
