The intracellular location of a key sulfur compound, dimethylsulfoniopropionate, was identified in microalgae and its subsequent uptake by marine bacteria was quantified using a combination of secondary-ion mass-spectrometry techniques.
Physical and chemical interactions with bacteria influence the life and death of Emiliania huxleyi, a bloom-forming micro-alga important in global biogeochemical cycles.
Dynamic successive blooms of clades of planktonic marine bacteria that can be observed during blooms of marine algae follow discernible patterns, part of which might be explained by substrate-induced forcing.
Single-cell analysis of the chloroplast redox response to high light and oxidative stress revealed light-dependent heterogeneity, and was linked to cell fate determination within isogenic diatom populations.
Multistability and regime shifts are common and species diversity is high in microbial communities when nutrient supplies are balanced and competing species have different stoichiometries of essential nutrients.
A fish-derived bile salt was shown to act as interspecific infochemical, inducing the widespread predator avoidance behavior diel vertical migration at picomolar concentrations in freshwater zooplankton of the genus Daphnia.
Bacteria reach swimming speeds of several hundred body lengths per second and change direction in less than 5 ms by using coordinated flagella bundle agitation.
In the context of an organism's ecology, physiology, and macroevolutionary history, inheritance and gene loss can yield emergent patterns of trait variability that give the appearance of gene acquisition.
SAK1, a novel cytoplasmic phosphoprotein, is a key intermediate component of the retrograde signaling pathway controlling nuclear gene expression during acclimation of Chlamydomonas cells to singlet oxygen stress.
An iron-sensitive gene cluster encodes proteins that co-localize with phytotransferrin endosomes and are involved in key intracellular iron transformation and trafficking processes in a model marine diatom.
