The regulatory switch from protection to assimilation, which plants use to exploit natural, fluctuating light, involves movement of the enzyme ferredoxin:NADP(H) oxidoreductase between chloroplast membrane complexes.
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.
Serial-Block-Face Scanning Electron Microscopy (SBF-SEM) associated with biomolecular analysis show that chloroplast differentiation proceeds by distinct ‘structure establishment’ and ‘chloroplast proliferation’ phases, each with differential protein and lipid regulation.
Light-harvesting complex stress-related is a protein from photosynthetic green algae that prevents damage from sunlight via two distinct conformational processes, which protect against different timescales of solar fluctuations.
Temperature-dependent fasciation mutants of Arabidopsis unexpectedly connect mitochondrial RNA processing to the control of cell proliferation during lateral root morphogenesis via electron transport chain activity and reactive oxygen species production.
Habitats of satellite-tracked blue sharks were shifted surfaceward by an oxygen minimum zone (OMZ) at depth thereby increasing their susceptibility to capture by longline fishing focused above the OMZ.
