The PP2A phosphatase associates with the Arabidopsis TRAPPII tethering complex and dephosphorylates a TRAPPII-derived phosphopeptide in vitro

Alexander Strohmayr, Alexander R. Steiner, Christian Wiese, Miriam Abele et autres

ABSTRACT The transport protein particle II (TRAPPII) complex is a conserved regulator of post-Golgi membrane trafficking. In Arabidopsis, phosphorylation of the TRAPPII-specific subunit TRS120 by SHAGGY-like kinases modulates adaptive growth responses, but the phosphatases that reverse this phosphorylation remain unknown. Here, proteomic …

Mitotic entry is controlled by the plant-specific phosphatase BSL1 and cyclin-dependent kinase B

Frej Tulin, Yalikunjiang Aizezi, Andres V. Reyes, Yuji Fujieda et autres

Cell cycle regulation is well understood in opisthokonts (fungi and metazoans) but not in plants or Apicomplexa, as some cell cycle regulators are not conserved. In opisthokonts, cell cycle progression requires the dephosphorylation of cyclin-dependent kinase (CDK) by the CDC25 phosphatase. Plants …

Mitotic entry is controlled by the plant-specific phosphatase BSL1 and cyclin-dependent kinase B

Abstract Cell cycle regulation is well understood in opisthokonts (fungi and metazoans) but not in plants and Apicomplexa, as some cell cycle regulators are not conserved 1–3 . In opisthokonts, cell cycle progression requires dephosphorylation of cyclin-dependent kinase (CDK) by the CDC25 …

Syntropic farming systems for reconciling productivity, ecosystem functions, and restoration

Johanna Jacobi, Christian Andrès, Farhah F. Assaad, Stéphane Bellon et autres

Inspired by the succession and vertical stratification found in nature, syntropic farming systems (SFS) incorporate annual and perennial plants in diversified farming systems. Numerous practice examples show the potential of SFS to enhance agroecosystems via optimised design and active management. Yet, scientific …

β-Carotene alleviates substrate inhibition caused by asymmetric cooperativity

Jieren Liao, Umar F. Shahul Hameed, Timothy D. Hoffmann, Elisabeth Kurze et autres

Abstract Enzymes are essential catalysts in biological systems. Substrate inhibition, once dismissed, is now observed in 20% of enzymes 1 and is attributed to the formation of an unproductive enzyme-substrate complex, with no structural evidence of unproductivity provided to date 1–6 . …

Cryo‐SEM and large volume FIB‐SEM of Arabidopsis cotyledons: Degradation of lipid bodies, biogenesis of glyoxysomes and reorganisation of organelles during germination

Gerhard Wanner, E. Schroeder-Reiter, Farhah F. Assaad

Until recently, the lack of three-dimensional visualisation of whole cells at the electron microscopic (EM) level has led to a significant gap in our understanding of the interaction of cellular organelles and their interconnection. This is particularly true with regard to the …

Ex situ germination of European acorns: data from 93 batches of 12 Quercus species

María Medina, Marino P. Reyes-Martín, Laura Levy, Alba Lázaro-González et autres

Abstract Key message We provide data on seedlot germination potential—a key trait related to regeneration—of 12 oak species. Germination was tested at the University of Granada following international protocols with 8985 acorns from 93 batches and 16 countries across Europe. Data on …

Regulation of adaptive growth decisions via phosphorylation of the TRAPPII complex in Arabidopsis

Christian Wiese, Miriam Abele, Benjamin Al, Melina Altmann et autres

Plants often adapt to adverse or stress conditions via differential growth. The trans-Golgi network (TGN) has been implicated in stress responses, but it is not clear in what capacity it mediates adaptive growth decisions. In this study, we assess the role of …
