Complete Genome Sequence of Chesapeake Bay Winter Synechococcus sp. Strain CBW1107, a Member of Subalpine Cluster II.

ABSTRACT: Here, we report the complete genome sequence of psychrotolerant Synechococcus sp. strain CBW1107, which was isolated from the Chesapeake Bay in winter. CBW1107 is a member of picocyanobacterial subalpine cluster II and exhibits greater cold tolerance than do most coastal and marine Synechococcus strains.

Complete Genome Sequences of Chesapeake Bay Synechococcus Strains CBW1002 and CBW1006 Isolated in Winter.

Project description:Synechococcus are picocyanobacteria with a cosmopolitan distribution. They are capable of surviving in a wide variety of environmental conditions. Synechococcus have been isolated from the Chesapeake Bay during winter months, and they show an impressive tolerance to cold temperatures. Cold-adapted Synechococcus are unique and diverse, as they have complex phylogenetic lineages closely related to subalpine cluster II, Bornholm Sea cluster, CB7 cluster, and some novel lineages which are independent from summer estuarine strains in subcluster 5.2. CBW1002 and CBW1006 are the first complete genomes to represent Bornholm Sea cluster Synechococcus strains. They have some of the largest genomes among the Synechococcus (3.8 Mb) and share many unique and cryptic homologs which could give insight into their ability to tolerate such cold and dynamic conditions in the Chesapeake Bay estuary.

Draft Genome Sequence of Synechococcus sp. Strain CB0101, Isolated From the Chesapeake Bay Estuary.

Project description:Here, we report the draft genome sequence of the estuarine Synechococcus sp. strain CB0101. The genomics information of this strain will facilitate the study of the poorly understood Synechococcus subcluster 5.2 and how this strain is capable of thriving in a dynamic estuarine system, such as the Chesapeake Bay.

Abundance and distribution of Synechococcus spp. and cyanophages in the Chesapeake Bay.

Project description:Despite the increasing knowledge of Synechococcus spp. and their co-occurring cyanophages in oceanic and coastal water, little is known about their abundance, distribution, and interactions in the Chesapeake Bay estuarine ecosystem. A 5-year interannual survey shows that Synechococcus spp. and their phages are persistent and abundant members of Chesapeake Bay microbial communities. Synechococcus blooms (10? cells ml?¹) were often observed in summer throughout the Bay, contributing 20 to 40% of total phytoplankton chlorophyll a. The distribution of phycoerythrin-containing (PE-rich) Synechococcus cells appeared to mostly correlate with the salinity gradient, with higher abundances at higher salinities. Cyanophages infectious to Synechococcus were also abundant (up to 6 × 10? viruses ml?¹ by the most probable number assay) during summer months in the Bay. The covariation in abundance of Synechococcus spp. and cyanophages was evident, although the latitude of observed positive correlation varied in different years, mirroring the changing environmental conditions and therefore the host-virus interactions. The impacts of cyanophages on host Synechococcus populations also varied spatially and temporally. Higher phage-related Synechococcus mortality was observed in drought years. Virus-mediated host mortality and subsequent liberation of dissolved organic matter (DOM) may substantially influence oceanic biogeochemical processing through the microbial loop as well as the microbial carbon pump. These observations emphasize the influence of environmental gradients on natural Synechococcus spp. and their phage population dynamics in the estuarine ecosystem.

Distinct patterns of picocyanobacterial communities in winter and summer in the Chesapeake Bay.

Project description:In the Chesapeake Bay, picocyanobacteria were usually 100-fold less abundant in winter than in summer. However, little is known about how picocyanobacterial populations shift between winter and summer in the bay. This is due mainly to undetectable winter picocyanobacterial populations in bacterial 16S rRNA clone libraries. In this study, the winter and summer picocyanobacterial populations in the bay were detected using picocyanobacterium-specific primers and were compared based on the analysis of rRNA internal transcribed spacer sequences. Temperature was found to be the dominant environmental factor controlling picocyanobacterial populations in the Chesapeake Bay. In the summer, marine cluster B Synechococcus dominated the upper bay, while a unique cluster, CB1 (marine cluster A [MC-A] Synechococcus), made up the vast majority in the middle and lower bay. In the winter, the picocyanobacteria shifted to completely different populations. Subclades CB6 and CB7, which belong to MC-A Synechococcus and Cyanobium, respectively, made up the entire winter picocyanobacterial populations in the bay. Interestingly, the winter members in subclade CB6 clustered closely with Synechococcus CC9311, a coastal strain known to have a greater capacity to sense and respond to changing environments than oceanic strains.

Metagenomic characterization of Chesapeake Bay virioplankton.

Project description:Viruses are ubiquitous and abundant throughout the biosphere. In marine systems, virus-mediated processes can have significant impacts on microbial diversity and on global biogeocehmical cycling. However, viral genetic diversity remains poorly characterized. To address this shortcoming, a metagenomic library was constructed from Chesapeake Bay virioplankton. The resulting sequences constitute the largest collection of long-read double-stranded DNA (dsDNA) viral metagenome data reported to date. BLAST homology comparisons showed that Chesapeake Bay virioplankton contained a high proportion of unknown (homologous only to environmental sequences) and novel (no significant homolog) sequences. This analysis suggests that dsDNA viruses are likely one of the largest reservoirs of unknown genetic diversity in the biosphere. The taxonomic origin of BLAST homologs to viral library sequences agreed well with reported abundances of cooccurring bacterial subphyla within the estuary and indicated that cyanophages were abundant. However, the low proportion of Siphophage homologs contradicts a previous assertion that this family comprises most bacteriophage diversity. Identification and analyses of cyanobacterial homologs of the psbA gene illustrated the value of metagenomic studies of virioplankton. The phylogeny of inferred PsbA protein sequences suggested that Chesapeake Bay cyanophage strains are endemic in that environment. The ratio of psbA homologous sequences to total cyanophage sequences in the metagenome indicated that the psbA gene may be nearly universal in Chesapeake Bay cyanophage genomes. Furthermore, the low frequency of psbD homologs in the library supports the prediction that Chesapeake Bay cyanophage populations are dominated by Podoviridae.

The narA locus of Synechococcus sp. strain PCC 7942 consists of a cluster of molybdopterin biosynthesis genes.

Project description:The narA locus required for nitrate reduction in Synechococcus sp. strain PCC 7942 is shown to consist of a cluster of genes, namely, moeA, moaC, moaD, moaE, and moaA, involved in molybdenum cofactor biosynthesis. The product of the moaC gene of strain PCC 7942 shows homology in its N-terminal half to MoaC from Escherichia coli and in its C-terminal half to MoaB or Mog. Overexpression of the Synechococcus moaC gene in E. coli resulted in the synthesis of a polypeptide of 36 kDa, a size that would conform to a protein resembling a fusion of the MoaC and MoaB or Mog polypeptides of E. coli. Insertional inactivation of the moeA, moaC, moaE, and moaA genes showed that the moeA-moa gene cluster is required for growth on nitrate and expression of nitrate reductase activity in strain PCC 7942. The moaCDEA genes constitute an operon which is transcribed divergently from the moeA gene. Expression of the moeA gene and the moa operon was little affected by the nitrogen source present in the culture medium.
