It takes two to tango: two GNOMs have to activate ARF1 together

Brumm et al. investigate how the protein GNOM activates dimers of the small GTPase ARF1 and inserts them very close to each other during vesicle formation. The Plant Cell (2020) https://doi.org/10.1105/tpc.20.00240 By Sabine Brumm 1,2 and Gerd Jürgens 1, ZMBP, University of Tübingen (1), Sainsbury…

Secret Talents: STARCH SYNTHASE 5—Not an Enzyme, but Very Active!

Abt et al. found that Arabidopsis SS5, a protein homologous to typical starch-synthesizing enzymes, is itself enzymatically inactive, but rather has an important role in the starch granule initiation process. Plant Cell https://doi.org/10.1105/tpc.19.00946 By Melanie R. Abt and Samuel C. Zeeman, Institute…

Copy Number Variations in the Arabidopsis Genome

Żmieńko et al. generate a catalog of large copy number variations in Arabidopsis, shedding light on the genetic basis of phenotypic variation. Plant Cell https://doi.org/10.1105/tpc.19.00640 By Agnieszka Żmieńko and Marek Figlerowicz, Institute of Bioorganic Chemistry, Polish Academy of Sciences,…

How Light Activates the Plant Circadian Clock

Liu et al. discover how members of the photosensory-signaling pathway orchestrate circadian clock gene expression to regulate plant responses to daily changes in the light environment. Plant Cell https://doi.org/10.1105/tpc.19.00981  Background: Plants use an endogenous time-keeping mechanism known…
