ABSTRACT The abundant and metabolically versatile aquatic bacterial order, Rhodobacterales , influences marine biogeochemical cycles. We assessed metagenome-assembled genome (MAG) abundance, estimated growth rates, potential expressed functions in the Chesapeake Delaware Bays, two important US estuaries. Phylogenomics of draft draft/closed genomes from this study others placed 46 nearly complete MAGs these bays into 11 genera, many were not well characterized. Their abundances varied between influenced by temperature, salinity, silicate phosphate concentrations. genera possessed unique shared genes for transporters, photoheterotrophy, complex carbon degradation, nitrogen, sulfur metabolism reflecting their seasonal differences abundance activity. Planktomarina genomospecies more ubiquitous than niche specialists, HIMB11, CPC320, LFER01, MED-G52. rates correlated to various factors including concentrations, cell density, light. Metatranscriptomic analysis four commonly revealed that aerobic anoxygenic photoheterotrophy-associated transcripts highly at night. These also differentially CO oxidation nutrient transport use different environmental conditions. Phosphate concentrations light penetration Bay likely contributed higher HIMB11 respectively, summer where they maintained ribosome prevented physiological gene expression constraints downregulating transporter compared Bay. Our highlights spatial temporal shifts estuarine within reflected through metabolisms, activity changes. IMPORTANCE In web global cycling, emerge as key players, exerting a profound influence dynamic While previous studies have primarily investigated organisms ecosystems, delves roles environments using combination metagenomic metatranscriptomic analyses. uncovered range generalists each exhibiting distinct patterns profiles. This diversity equips them with capacity thrive amidst varying conditions encountered habitats. Crucially, our findings illuminate adaptable nature revealing energy production pathways diverse resource management, especially during phytoplankton or algal blooms. Whether adopting free-living particle-attached existence, demonstrate remarkable flexibility metabolic strategies, underscoring pivotal role driving ecosystem dynamics ecosystems.
