DMSP在海洋藻-菌互作中的作用研究进展

Research progress of DMSP in marine algae-bacteria interaction

  • 摘要: 二甲基巯基丙酸内盐(dimethylsulphioniopropionate,DMSP)为海洋中的主要硫源,最早从藻类中分离,其挥发性代谢物二甲基硫(DMS)为大气中影响全球气候的重要因素。目前发现DMSP在不同藻、菌中的合成与降解途径体现出多元化的特征,但其代谢途径的选择及不同代谢物对藻际微环境中藻-菌关系的影响缺乏更进一步的研究。本文综述了关于藻-菌之间DMSP合成和降解路径的最新发现,对DMSP在不同生物类群中的功能进行了梳理,并提出其作为藻际中心信号分子,可能通过影响细菌化学趋向性,或群感效应,或合成抗生素等途径影响藻-菌关系。

     

    Abstract: Dimethylsulphioniopropionate (DMSP) is the most abundant sulfur source in the ocean and firstly isolated from marine algae. The volatile metabolic product of DMSP, dimethyl sulfide (DMS), is the key factor in atmosphere that influencing global climate. Currently, various synthetic and metabolic pathways were detected in marine algae and bacteria, but it is still unknown how different pathways were chosen and how the metabolic products affect algae-bacteria interactions in phycosphere. This review summarizes the synthetic and catabolic pathways of DMSP in different marine organisms, and the possible action mode of DMSP in marine environment, especially in algae-bacteria interaction. As the key signaling molecular in phycosphere, DMSP may regulate algae-bacteria interaction through various pathways, such as chemotaxis, quorum sensing, or antibiotic synthesis.
