Scaffolding proteins guide the evolution of algal light harvesting antennas
Cryptophytes acquired plastids from red algae but replaced the light-harvesting phycobilisome with a unique cryptophyte antenna. Here via analysis of phycobilisome cryo-EM structures, Rathbone et al.

Seasonal Compositions of Size-Fractionated Surface Phytoplankton Communities in the Yellow Sea
Little information on the phytoplankton community in the Yellow Sea (YS)—especially size-fractionated phytoplankton—is currently available, in comparison to the various physicochemical studies in the literature.

Abstract How organisms assemble to form a community is a central question in ecology, with commonly inferred mechanisms including environmental filtering, competitive exclusion, and random processes. In community phylogenetics, phylogenetic clustering is often interpreted as evidence of environmental filtering, where closely related species with ...

Dimorphism in cryptophytes—The case of Teleaulax amphioxeia/Plagioselmis prolonga and its ecological implications [PDF]
Growing evidence suggests that sexual reproduction might be common in unicellular organisms, but observations are sparse. Limited knowledge of sexual reproduction constrains understanding of protist ecology. Although Teleaulax amphioxeia and Plagioselmis

High-resolution metagenomic reconstruction of the freshwater spring bloom
Background The phytoplankton spring bloom in freshwater habitats is a complex, recurring, and dynamic ecological spectacle that unfolds at multiple biological scales.

Abstract B‐vitamins are organic cofactors required by prokaryotic and eukaryotic planktonic cells; their availability impacts aquatic microbial communities and associated biogeochemistry. Despite their ecological importance, B‐vitamin dynamics and their relationships to plankton composition in estuaries are unclear, limiting our understanding of ...

Cryptic Cryptophytes – revision of the genus Goniomonas
Abstract Cryptomonad protists are ubiquitously distributed over marine and freshwater habitats. As an exception to the coloured cryptomonads, the heterotrophic cryptomonads of the genus Goniomonas have an ancestral phylogenetic position.

Abstract Unicellular diazotrophic cyanobacteria contribute up to ~50% of marine N2 fixation, and Crocosphaera watsonii, characterized by high phycoerythrin (PE) content, is among one of the key species in tropical and subtropical oceans. Although recent observations have revealed heterogeneous N2 fixation activity within C.

Presence of state transitions in the cryptophyte algaGuillardia theta [PDF]
Plants and algae have developed various regulatory mechanisms for optimal delivery of excitation energy to the photosystems even during fluctuating light conditions; these include state transitions as well as non-photochemical quenching. The former process maintains the balance by redistributing antennae excitation between the photosystems, meanwhile ...

Estuaries are highly productive ecosystems, which are strongly affected by several anthropogenic pressures. Phytoplankton is a key element for assessing the ecological quality status in these transitional waters.
