This work introduces Waterburya agarophytonicola Bonthond and Shalygin gen. nov., sp. nov, a baeocyte producing cyanobacterium that was isolated from the rhodophyte Agarophyton vermiculophyllum (Ohmi) Gurgel et al., an invasive seaweed that has spread across the northern hemisphere. The new species genome reveals a diverse repertoire of chemotaxis and adhesion related genes, including genes coding for type IV pili assembly proteins and a high number of genes coding for filamentous hemagglutinin family (FHA) proteins. Among a genetic basis for the synthesis of siderophores, carotenoids and numerous vitamins, W. agarophytonicola is potentially capable of producing cobalamin (vitamin B), for which A. vermiculophyllum is an auxotroph. With a taxonomic description of the genus and species and a draft genome, this study provides as a basis for future research, to uncover the nature of this geographically independent association between seaweed and cyanobiont.
这项工作介绍了 Waterburya agarophytonicola Bonthond 和 Shalygin gen. nov.，sp. nov.，这是一种产生蓝细菌的粘细菌，从红藻 Agarophyton vermiculophyllum（Ohmi）Gurgel 等人中分离出来，该藻类是一种已在北半球广泛传播的入侵性海藻。新物种的基因组揭示了一系列多样化的趋化性和粘附相关基因，包括编码 IV 型菌毛组装蛋白的基因和大量编码丝状血凝素家族（FHA）蛋白的基因。在合成铁载体、类胡萝卜素和许多维生素的遗传基础上，W. agarophytonicola 可能能够产生钴胺素（维生素 B），而 A. vermiculophyllum 是其营养缺陷型。本研究对属和种进行了分类描述，并提供了基因组草案，为未来的研究提供了基础，以揭示海藻和蓝细菌之间这种地理上独立的关联的本质。
