These interactions are shaped through exchanges of primary and secondary metabolites provided by one of the partners. Metabolites, such as N-sources or vitamins, can be beneficial to the partner and they may be assimilated through chemotaxis towards the partner producing these metabolites. Other metabolites, especially many natural products synthesized by bacteria, can act as toxins and damage or kill the partner. For instance, the green microalga Chlamydomonas reinhardtii establishes a mutualistic partnership with a Methylobacterium , in stark contrast to its antagonistic relationship with the toxin producing Pseudomonas protegens . In other cases, as with a coccolithophore haptophyte alga and a Phaeobacter bacterium, the same alga and bacterium can even be subject to both processes, depending on the secreted bacterial and algal metabolites. Some bacteria also influence algal morphology by producing specific metabolites and micronutrients, as is observed in some macroalgae. This review focuses on algal-bacterial interactions with micro- and macroalgal models from marine, freshwater, and terrestrial environments and summarizes the advances in the field. It also highlights the effects of temperature on these interactions as it is presently known. 4950 https://doi.org/10.3390/plants13060829$xR$3Volltext$534 4950 https://nbn-resolving.org/urn:nbn:de:gbv:27-dbt-20240418-135730-002$xR$3Volltext$534 4961 https://www.db-thueringen.de/receive/dbt_mods_00060141 5051 570 5550 antagonism 5550 brown algae 5550 diatoms 5550 dinoflagellates 5550 green algae 5550 haptophytes 5550 mutualism 5550 primary metabolites 5550 red algae 5550 secondary metabolites
