Differential Activity of Coexisting Prochlorococcus Ecotypes [PDF]

Frontiers in Marine Science, 2019
The abundance and widespread distribution of the unicellular cyanobacterium Prochlorococcus is attributed to its extensive genetic diversity. At least twelve distinct clades, or ecotypes, of Prochlorococcus have been discovered so far, and follow ...

Transcriptional Mechanisms of Thermal Acclimation in Prochlorococcus

mBio, 2023
Low temperature limits the growth and the distribution of the key oceanic primary producer Prochlorococcus, which does not proliferate above a latitude of ca. 40°. Yet, the molecular basis of thermal acclimation in this cyanobacterium remains unexplored.

Prochlorococcus and Synechococcus have evolved different adaptive mechanisms to cope with light and UV stress [PDF]

Frontiers in Microbiology, 2012
Prochlorococcus and Synechococcus, which numerically dominate vast oceanic areas, are the two most abundant oxygenic phototrophs on Earth. Although they require solar energy for photosynthesis, excess light and associated high UV radiations can induce ...

Nanopore Long-Read Metagenomics Reveals Pollution-Driven Antibiotic Resistance and Xenobiotic Degradation in Urban Beach Microbiomes. [PDF]

Environ Microbiol Rep
Using nanopore metagenomics, this study reveals that anthropogenic pollution drives ecological and functional shifts in coastal microbiomes. Pristine island environments act as stable, Prochlorococcus‐dominated baselines, whereas urban beaches function as hotspots for opportunistic taxa, harbouring a robust genomic potential for xenobiotic degradation ...

Phycobilisomes: modular light-harvesting systems of cyanobacteria and red algae. [PDF]

Plant J
SUMMARY Phycobilisomes (PBSs) are supramolecular pigment–protein complexes that function as the principal light‐harvesting antennae in cyanobacteria, red algae (Rhodophyta), and glaucophytes, and to a lesser extent in cryptophytes. Because the intrinsic chlorophyll‐based antennae of the photosystems absorb poorly in the green region of the spectrum ...

Quantitative Proteomics Shows Extensive Remodeling Induced by Nitrogen Limitation in Prochlorococcus marinus SS120

mSystems, 2017
Prochlorococcus requires the capability to accommodate to environmental changes in order to proliferate in oligotrophic oceans, in particular regarding nitrogen availability.

Picophytoplankton in the West Pacific Ocean: A Snapshot

Frontiers in Microbiology, 2022
Marine picophytoplankton have crucial ecological value and make an important contribution to marine primary productivity. While biomass of phytoplankton in general is projected to decline as a result of global warming, picophytoplankton will likely ...

Diel rhythmicity in amino acid uptake by Prochlorococcus [PDF]

, 2008
The marine cyanobacterium Prochlorococcus, the most abundant phototrophic organism on Earth, numerically dominates the phytoplankton in nitrogen (N)-depleted oceanic gyres.

Dynamics of Prochlorococcus Diversity and Photoacclimation During Short-Term Shifts in Water Column Stratification at Station ALOHA

Frontiers in Marine Science, 2018
The cyanobacterium Prochlorococcus is the dominant phototroph in surface waters of the vast oligotrophic oceans, the foundation of marine food webs, and an important component of global biogeochemical cycles.
