[HTML][HTML] Single-cell measurements and modelling reveal substantial organic carbon acquisition by Prochlorococcus

Z Wu, D Aharonovich, D Roth-Rosenberg… - Nature …, 2022 - nature.com
Marine phytoplankton are responsible for about half of the photosynthesis on Earth. Many
are mixotrophs, combining photosynthesis with heterotrophic assimilation of organic carbon, …

Particle‐associated and free‐living bacterial communities in an oligotrophic sea are affected by different environmental factors

D Roth Rosenberg, M Haber, J Goldford… - Environmental …, 2021 - Wiley Online Library
In the oceans and seas, environmental conditions change over multiple temporal and
spatial scales. Here, we ask what factors affect the bacterial community structure across time, …

Prochlorococcus Cells Rely on Microbial Interactions Rather than on Chlorotic Resting Stages To Survive Long-Term Nutrient Starvation

D Roth-Rosenberg, D Aharonovich, T Luzzatto-Knaan… - MBio, 2020 - Am Soc Microbiol
Many microorganisms produce resting cells with very low metabolic activity that allow them
to survive phases of prolonged nutrient or energy stress. In cyanobacteria and some …

A year in the life of the Eastern Mediterranean: Monthly dynamics of phytoplankton and bacterioplankton in an ultra-oligotrophic sea

…, A Tsemel, D Aharonovich, D Roth-Rosenberg… - Deep Sea Research …, 2022 - Elsevier
The Eastern Mediterranean Sea (EMS) is a poorly studied ultra-oligotrophic marine environment,
dominated by small-size phyto- and bacterioplankton. Here, we describe the dynamics …

[HTML][HTML] Spatiotemporal variation of microbial communities in the ultra-oligotrophic Eastern Mediterranean Sea

M Haber, D Roth Rosenberg, M Lalzar… - Frontiers in …, 2022 - frontiersin.org
Marine microbial communities vary seasonally and spatially, but these two factors are rarely
addressed together. In this study, the temporal and spatial patterns of the bacterial and …

Prochlorococcus in the lab and in silico: The importance of representing exudation

M Grossowicz, D RothRosenberg… - Limnology and …, 2017 - Wiley Online Library
In this study, we test the applicability of the Droop/Caperon internal stores model to describe
the growth and decline of the globally abundant marine cyanobacterium Prochlorococcus in …

Dynamic macromolecular composition and high exudation rates in Prochlorococcus

D RothRosenberg, D Aharonovich… - Limnology and …, 2021 - Wiley Online Library
Every living cell is composed of macromolecules such as proteins, DNA, RNA, and pigments.
The ratio between these macromolecular pools depends on the allocation of resources …

Microbial communities in an ultra-oligotrophic sea are more affected by season than by distance from shore

M Haber, DR Rosenberg, M Lalzar, I Burgsdorf… - bioRxiv, 2020 - biorxiv.org
Marine microbial communities vary seasonally and spatially, but these two factors are rarely
addressed together. We studied temporal and spatial patterns of the microbial community …

Prochlorococcus rely on microbial interactions rather than on chlorotic resting stages to survive long-term nutrient starvation

D Roth-Rosenberg, D Aharonovich, T Luzzatto-Knaan… - bioRxiv, 2019 - biorxiv.org
Many microorganisms produce resting cells with very low metabolic activity that allow them
to survive phases of prolonged nutrient or energy stress. In cyanobacteria and some …
