Prochlorococcus Exudate Stimulates Heterotrophic Bacterial Competition with Rival Phytoplankton for Available Nitrogen

bioRxiv, 2021
In nutrient-poor habitats, competition for limited resources is thought to select for organisms with an enhanced ability to scavenge nutrients and utilize them efficiently.

Frequency of mispackaging ofProchlorococcusDNA by cyanophage [PDF]

The ISME Journal, 2020
ABSTRACTProchlorococcuscells are the numerically dominant phototrophs in the open ocean. Cyanophages that infect them are thus a notable fraction of the total viral population in the euphotic zone, and, as vehicles of horizontal gene transfer, appear to drive their evolution.

Plastic leachates impair growth and oxygen production in Prochlorococcus, the ocean’s most abundant photosynthetic bacteria

Communications Biology, 2019
Plastic pollution is a global threat to marine ecosystems. Plastic litter can leach a variety of substances into marine environments; however, virtually nothing is known regarding how this affects photosynthetic bacteria at the base of the marine food ...

Phototroph-heterotroph interactions during growth and long-term starvation across Prochlorococcus and Alteromonas diversity

bioRxiv, 2021
Due to their potential impact on ecosystems and biogeochemistry, microbial interactions, such as those between phytoplankton and bacteria, have been studied intensively using specific model organisms.

Novel isolates expand the physiological diversity of Prochlorococcus and illuminate its macroevolution. [PDF]

mBio, 2023
Prochlorococcus is a diverse picocyanobacterial genus and the most abundant phototroph on Earth. Its photosynthetic diversity divides it into high-light (HL)- or low-light (LL)-adapted groups representing broad phylogenetic grades—each composed of ...

Glucose uptake in Prochlorococcus: diversity of kinetics and effects on the metabolism [PDF]

, 2017
We have previously shown that Prochlorococcus sp. SS120 strain takes up glucose by using a multiphasic transporter encoded by the Pro1404 gene. Here, we studied the glucose uptake kinetics in multiple Prochlorococcus strains from different ecotypes ...

Emergence of Prochlorococcus in the Tonian oceans and the initiation of Neoproterozoic oxygenation

bioRxiv
Prochlorococcus are the smallest and most abundant photosynthetic organisms on Earth, contributing up to 50% of the chlorophyll in the oligotrophic oceans.

Heterotroph Interactions Alter Prochlorococcus Transcriptome Dynamics during Extended Periods of Darkness [PDF]

, 2018
Microbes evolve within complex ecological communities where biotic interactions impact both individual cells and the environment as a whole. Here we examine how cellular regulation in the marine cyanobacterium Prochlorococcus is influenced by a ...

A single Prochlorococcus ecotype dominates the tropical Bay of Bengal with ultradian growth.

Environmental Microbiology
The Bay of Bengal (BoB) spans >2.2 million km2 in the northeastern Indian Ocean and is bordered by dense populations that depend upon its resources.

Emergence of metabolic coupling to the heterotroph Alteromonas promotes dark survival in Prochlorococcus

bioRxiv
Prochlorococcus is found throughout the euphotic zone in the oligotrophic open ocean. Deep mixing and sinking while attached to particles can, however, transport Prochlorococcus cells below this sunlit zone, depriving them of light for extended periods ...
