ABSTRACT The diversity of the marine cyanobacterium Synechococcus can be broadly separated into clades, with clade II typically present in warm oligotrophic water, and clades I IV found cooler coastal water. We amplicon sequence variants (ASVs) belonging to nutrient‐replete waters San Diego Bay (SDB). Using 16S rRNA gene, 18S gene internal transcribed spacer region sequencing, we analysed multiple locations SDB monthly for over a year, additional samples dating back 2015. community composition differed from nearby coast terms dominant ASVs. Specific ASVs became relatively more abundant towards bay showed seasonality, higher relative abundance months. Select group phylogenetically show similar seasonal spatial distribution patterns, indicating these have adapted SDB. Isolates matching pigment that is better green light available SDB, further supporting our findings. Other microbial taxa also enrichment, providing evidence chemostat‐like environment where circulation, temperature, other environmental conditions create zone evolution diversification.

Microbes respond to changes in their environment by adapting physiology through coordinated adjustments the expression levels of functionally related genes. To detect these shifts situ, we developed a sparse tensor decomposition method that derives gene co-expression patterns from inherently complex whole community RNA sequencing data. Application metatranscriptomes abundant marine cyanobacteria Prochlorococcus and Synechococcus identified responses scarcity two essential nutrients, nitrogen iron, including increased transporter expression, restructured photosynthesis carbon metabolism, mitigation oxidative stress. Further, profiles clusters suggest both populations experience simultaneous iron stresses transition zone between North Pacific oceanic gyres.

Abstract Seasonal and El Niño-Southern Oscillation (ENSO) warming result in similar ocean changes as predicted with climate change. Climate-driven environmental cycles have strong impacts on microbiome diversity, but function are poorly understood. Here we quantify microbial genomic diversity functioning over 11 years covering seasonal ENSO at a coastal site the southern California Current. We observe oscillations between large-genome lineages during cold, nutrient rich conditions winter spring versus small-genome lineages, including Prochlorococcus Pelagibacter , summer fall. Parallel interannual separate communities depending condition. Biodiversity shifts translate into clear functional potential. Ocean induced an ecosystem less iron more macronutrient stress genes, depressed organic carbon degradation potential biomass, elevated carbon-to-nutrient biomass ratios. The consistent response observed across time-scales points towards large climate-driven marine ecosystems biogeochemical cycles.

Molecular studies about cyanide biodegradation have been mainly focused on the hydrolytic pathways catalyzed by dihydratase CynD or nitrilase NitC. In some Pseudomonas strains, assimilation of has linked to NitC, such as cyanotrophic model strain pseudoalcaligenes CECT 5344, which recently reclassified oleovorans 5344. this work, a phylogenomic approach established more precise taxonomic position 5344 within species P. oleovorans. Furthermore, pan-genomic analysis and other with fluorescens monteilii, allowed for comparison identification cioAB mqoAB genes involved in resistance, nitC cynS required cyanate, respectively.
