Quantitative proteomics insights into Chlamydomonas reinhardtii thermal tolerance enhancement by a mutualistic interaction with Sinorhizobium meliloti.

ABSTRACT: Interactions between photosynthetic microalgae and bacteria impact the physiology of both partners, which influence the fitness and ecological trajectories of each partner in an environmental context-dependent manner. Thermal tolerance of Chlamydomonas reinhardtii can be enhanced through a mutualistic interaction with vitamin B₁₂ (cobalamin)-producing Sinorhizobium meliloti. Here, we used label-free quantitative proteomics to reveal the metabolic networks altered by the interaction under normal and high temperatures. We created a scenario where the growth of Sinorhizobium requires carbon provided by Chlamydomonas for growth in co-cultures, and survival of Chlamydomonas under high temperatures relies on cobalamin and possibly other metabolites p
