This study aims to reveal seasonal dynamics picoplankton in subtropical current. Our results showed that one picocyanobacteria, Synechococcus, mainly distributed surface water layer regardless changes, cell abundance ranged from 104 105 cells mL−1. In contrast, maximum concentration other Prochlorococcus, was maintained at more than mL−1 throughout year. summer autumn, Prochlorococcus were concentrated near bottom euphotic zone.

ABSTRACT Cyanobacteria are intricately linked with its microbiome through multiple metabolic interactions. We assessed how these interactions might be affected by cyanophage infection and lysis in cyanobacterium Nodularia spumigena . The genome‐scale models analysis of putative revealed a bidirectional cross‐feeding potential within the N. microbiome, heterotrophic bacteria exhibiting greater level trophic dependency on cyanobacterium. Our results indicate that microbes associated rely supply various amino acids, reduced carbon compounds protein synthesis cofactors released cyanobacterial host. observed compositional changes were multiplicity increased increasing initial viral load. Higher mortality led to decreased variability relative abundances bacteria, suggesting an indirect restriction their niche space.

Abstract Cyanophages, together with their host cyanobacteria, play important roles in marine biogeochemical cycles and control of food webs. The recently identified MPP-C (Marine Picocyanobacteria Podovirus clade C) cyanophages, belonging to the T7-like podoviruses, contain smallest genomes among cyanopodoviruses exhibit distinct infection kinetics. However, understanding cyanophage process is hindered by lack high-resolution structural information. Here, we report cryo-EM structure P-SCSP1u, a representative member phages, its native form at near-atomic resolution, which reveals assembly mechanism capsid molecular interaction portal-tail complex. Structural comparison proteins P-SCSP1u other podoviruses known structures provides insights into evolution viruses.
