The TPL corepressor binds to the core mediator complex through MED21 to inhibit transcription while simultaneously priming repressed genes for rapid reactivation.
Arabidopsis shows extensive genetic diversity in germination time distributions, which can be explained by the underlying ABA/GA network functioning as a noisy bistable switch.
The expression of Arabidopsis NLR immune response genes is modulated by premature transcription termination, and this has implications for understanding NLR regulation and evolutionary dynamics.
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.
SABRE, which is present in a wide range of eukaryotes, localizes to ER subdomains in plants, impacting cell expansion and callose deposition during cell plate maturation.
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.
Epigenetic reprogramming of the distinct repressive marks H3K27me3 or H3K9me2 guides the transition between the haploid and diploid life forms that encompass the life cycle of land plants.
