Conserve and sustainably use the oceans, seas and marine resources for sustainable development ASLO Aquatic Sciences Meeting, Resilience and Recovery in Aquatic Systems, 4-9 June 2023, Palma de Mallorca, Spain It is well known that oligotrophic taxa dominate marine microbial ecosystems, although, under certain conditions such as phytoplankton blooms, some copiotrophs can dramatically increase their abundance and reach towering proportions of bacterial communities. We are uncertain whether bacteria that do so, the so-called bloomers, have specific functional characteristics or if, instead, they are randomly selected among all copiotrophs. To test this hypothesis, we conducted a comparative genomic analysis with taxa from microcosm experiments where grazer and viral presence was reduced and nutrient availability was increased, factors that induced bacterial blooms. We tested the correlation between experimental growth rates and proportions of functional genes from a total of 203 genomes from isolates, metagenome-assembled genomes and representatives GTDB species which were classified into copiotrophs and oligotrophs according to their codon usage bias. We found that signal transduction mechanisms (especially two-component systems) and transcriptional regulation were the best correlated functional categories, followed by cell motility, ion transport, defense mechanisms and membrane-related functions. Copiotrophic taxa from classes Gammaproteobacteria and Alphaproteobacteria, Bacteroidia and Verrucomicrobiae showed comparatively high proportions of genes related to all or some of these categories. In this study we provide insights into the functional characteristics that allow certain copiotrophs to rapidly respond to changes in the environment and, potentially, develop blooms Peer reviewed 2024-04-18T10:31:37Z 2024-04-18T10:31:37Z 2023-06-06 comunicación de congreso ASLO Aquatic Sciences Meeting (2023) http://hdl.handle.net/10261/354235 en Sí none Association for the Sciences of Limnology and Oceanography
