Quantitative live-cell time-lapse imaging reveals that the spatial and temporal degree of cortical polarity domains reflects stem-cell division capacity in cells of the Arabidopsis plant leaf epidermis.
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.
A basidiomycete yeast closely related to fungal smuts is an antagonistic microbe in the Arabidopsis leaf phyllosphere that inhibits infection by Albugo laibachii via a GH25 hydrolase with lysozyme activity.
