Prochlorococcus marinus , the dominant photosynthetic organism in ocean, is found two main ecological forms: high-light-adapted genotypes upper part of water column and low-light-adapted at bottom illuminated layer. P. SS120, complete genome sequence reported here, an extremely form. The SS120 composed a single circular chromosome 1,751,080 bp with average G+C content 36.4%. It contains 1,884 predicted protein-coding genes size 825 bp, rRNA operon, 40 tRNA genes. Together 1.66-Mbp MED4, one...
Summary Marine cyanobacteria of the genera Prochlorococcus and Synechococcus are important contributors to global primary production occupying a key position at base marine food webs. The genetically diverse nature each genus is likely an reason for their successful colonization vast tracts world's oceans, feature that has led detailed analysis distribution these genetic lineages local ocean basin scale. Here, we extend analyses dimension, using new data from cruises in Pacific, Indian...
Abstract Background The picocyanobacterial genus Synechococcus occurs over wide oceanic expanses, having colonized most available niches in the photic zone. Large scale distribution patterns of different clades (based on 16S rRNA gene markers) suggest occurrence two major lifestyles ('opportunists'/'specialists'), corresponding to distinct broad habitats ('coastal'/'open ocean'). Yet, genetic basis niche partitioning is still poorly understood this ecologically important group. Results Here,...
Ocean Sampling Day was initiated by the EU-funded Micro B3 (Marine Microbial Biodiversity, Bioinformatics, Biotechnology) project to obtain a snapshot of marine microbial biodiversity and function world's oceans. It is simultaneous global mega-sequencing campaign aiming generate largest standardized data set in single day. This will be achievable only through coordinated efforts an Consortium, supportive partnerships networks between sites. commentary outlines establishment, aims Consortium...
Prochlorococcus and Synechococcus are the two most abundant widespread phytoplankton in global ocean. To better understand factors controlling their biogeography, a reference database of high-resolution taxonomic marker petB, encoding cytochrome b6, was used to recruit reads out 109 metagenomes from Tara Oceans expedition. An unsuspected novel genetic diversity unveiled within both genera, even for well-characterized clades, 136 divergent petB sequences were successfully assembled...
Marine Synechococcus owe their specific vivid color (ranging from blue-green to orange) large extrinsic antenna complexes called phycobilisomes, comprising a central allophycocyanin core and rods of variable phycobiliprotein composition. Three major pigment types can be defined depending on the found in (phycocyanin, phycoerythrin I or II). Among strains containing both phycoerythrins II, four subtypes distinguished based ratio two chromophores bound these phycobiliproteins. Genomes eleven...

Living resources in the sea are essential to economic, nutritional, recreational, and health needs of billions people. Variation biodiversity that characterizes marine systems, which underlies numerous ecosystem services provided humans, is being rapidly altered by changing environmental factors human activity. Understanding underlying causes these patterns, forecasting where future changes likely occur, requires monitoring patterns organism abundance, diversity, distribution health;...
Summary Conserved markers such as the 16S rRNA gene do not provide sufficient molecular resolution to identify spatially structured populations of marine Synechococcus , or ‘ecotypes’ adapted distinct ecological niches. Multi‐locus sequence analysis targeting seven ‘core’ genes was employed taxonomically resolve isolates and correlate previous phylogenetic analyses encompassing a range markers. Despite recognized importance lateral transfer in shaping genomes cyanobacteria, multi‐locus more...
Drones or unmanned Aerial Vehicles' (UAVs) have huge potential to improve the safety and efficiency of sample collection from wild animals under logistically challenging circumstances. Here we present a method for surveying population health that uses UAVs respiratory vapour, 'whale blow', exhaled by free-swimming humpback whales (Megaptera novaeangliae), coupled this with amplification sequencing tract microbiota. We developed low-cost multirotor UAV incorporating sterile petri dish...
Significance High-resolution data covering marine microbes and microeukaryotes are sparse, even though these organisms control global biogeochemical cycles. Here we present a dataset describing the microbial pro- eukaryotic diversity along 7,000-km transect from Antarctic ice edge to equator in South Pacific Ocean. We show that ( i ) temperature is not primary driver of richness gradients, ii prokaryotic increases with productivity, iii oceanographic features can structure eukaryotes. Our...
Abstract Marine heatwaves (MHWs) cause disruption to marine ecosystems, deleteriously impacting macroflora and fauna. However, effects on microorganisms are relatively unknown despite ocean temperature being a major determinant of assemblage structure. Using data from thousands Southern Hemisphere samples, we reveal that during an “unprecedented” 2015/16 Tasman Sea MHW, temperatures approached or surpassed the upper thermal boundary many endemic taxa. Temperate microbial assemblages...
Abstract. Biological communities populating the Mediterranean Sea, which is situated at northern boundary of subtropics, are often claimed to be particularly affected by global warming. This indicated, for instance, introduction (sub)tropical species fish or invertebrates that can displace local species. raises question whether microbial similarly affected, especially in Levantine basin where sea surface temperatures have significantly risen over last 25 years (0.50 ± 0.11 °C average per...
In daily operation, railway traffic always deviates from the planned schedule to a certain extent. Primary initial delays of trains may cause whole cascade secondary other over entire network. this paper, we propose stochastic model for delay propagation and forecasts arrival departure events which is applicable all kind public transport (not only traffic). Our fairly realistic, it includes general waiting policies (how long do wait delayed feeder trains), uses driving time profiles...
There is growing interest in characterizing the viromes of diverse mammalian species, particularly context disease emergence. However, little known about virome diversity aquatic mammals, part due to difficulties sampling. We characterized exhaled breath (or blow) Eastern Australian humpback whale (Megaptera novaeangliae). To achieve an unbiased survey diversity, a meta-transcriptomic analysis was performed on 19 pooled blow samples collected via purpose-built Unmanned Aerial Vehicle (UAV,...
Marine picocyanobacteria of the genera Prochlorococcus and Synechococcus are most abundant photosynthetic organisms on Earth, an ecological success thought to be linked differential partitioning distinct ecotypes into specific niches. However, underlying processes that governed diversification these microorganisms appearance niche-related phenotypic traits just starting elucidated. Here, by comparing 81 genomes, including 34 new Synechococcus, we explored evolutionary shaped genomic...

Abstract The ever-increasing number of available microbial genomes and metagenomes provides new opportunities to investigate the links between niche partitioning genome evolution in ocean, especially for abundant ubiquitous marine picocyanobacteria Prochlorococcus Synechococcus. Here, by combining metagenome analyses Tara Oceans dataset with comparative genomics, including phyletic patterns genomic context individual genes from 256 reference genomes, we show that picocyanobacterial...
