Lena Maria Müller Boyce Thompson Institute, Ithaca, NY, USA Nitrogen (N) is a critical element in plant nutrition and an important building block of amino acids, nucleic acids, and secondary metabolites. Roots take up N mainly in the form of nitrate (NO3–) and ammonium (NH4+). To feed a growing human population and maintain plant growth […]
Waadt et al. use a suite of genetically encoded biosensors to monitor signaling compound concentration changes and how they overlap in time and space. Plant Cell https://doi.org/10.1105/tpc.19.00892 By Rainer Waadt Background: To survive, plants need to sense the environment and adjust their growth and development according to the conditions they face. One part of the […]

Cotton is currently the most common textile fiber used worldwide, […]
Bacteria use stomatal pores as a point of entry to invade plant leaves. As a first line of defense, plants attempt to counteract this attack by restricting bacterial entry simply by closing the stomata. This happens via reduction in turgor pressure of the two guard cells flanking the stomatal pore, the “double doors” of the […]
Sugars have a key role in numerous cellular processes, and thus their storage and distribution are tightly controlled to ensure appropriate access when needed. In plants, the vacuole is the major storage organelle. The tonoplast (vacuole membrane) contains various transporters that regulate sugar and nutrient balances within the cell, including members of the TONOPLAST SUGAR […]
Ganguly et al. establish that a transporter protein helps stabilize cell wall deposition sites.

Author Anne-Sophie Fiorucci Affiliation Centre for Integrative Genomics, Faculty of Biology and Medicine, Génopode Building, University of Lausanne, CH-1015 Lausanne, Switzerland. ORCID number 0000-0002-3254-5967 DNA replication allows doubling of the genomic content of a cell before division. In eukaryotes, it starts at multiple places called origins of replication (ORI) where the replication machinery is loaded […]
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 Laboratory, University of Cambridge (2) Background: Eukaryotic cells deliver one […]
Marc-Sven Roell1 ORCID ID: 0000-0003-2714-8729 1Institute of Plant Biochemistry, Heinrich-Heine University Düsseldorf, Universitätsstrasse 1, 40225 Düsseldorf, Germany [email protected] To cope with various abiotic and biotic stress factors, plants must be facile in adapting cellular metabolism. In particular, they have to adjust photosynthesis and balance associated metabolism. Heat and drought stress strengthen plant photorespiration, a metabolic […]
