Measurements of specialized metabolites across a population of 800 natural Arabidopsis thaliana accessions revealed different pressures and evolutionary processes that shaped their variation and distribution across Europe.
A potentially useful cyanobacterial sulfated exopolysaccharide and its biosynthesis and regulation genes, which contribute to the laboratorial bloom formation, are elucidated for the first time among prokaryotes.

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.
