O’Leary et al. show that the TOR signalling pathway in plants responds to amino acid levels by eliciting regulatory effects on respiratory energy metabolism at night, uniting a hallmark mechanism of TOR regulation across eukaryotes. Plant Cell https://doi.org/10.1105/tpc.19.00157 By Brendan O’Leary and Harvey Millar Background: Plant leaves have two main energy-generating metabolic systems, photosynthesis and […]
Aung et al. reveal that pathogenic bacteria target plant plasmodesmata to colonize and invade surrounding tissues. Plant Cell https://doi.org/10.1105/tpc.19.00707 By Kyaw Aung and Sheng Yang He Background: Multicellular organisms like animals and plants host a multitude of microorganisms. Although most microbes are beneficial or harmless to their hosts, infections caused by pathogenic microorganisms can […]
Reddit et al. show that an effector protein from a pathogen modifies a host factor by ADP ribosylation, thereby activating defenses. The Plant Cell https://doi.org/10.1105/tpc.19.00020 Background: To protect themselves against disease, plants employ a family of intracellular receptors called disease resistance (R) proteins. Most R proteins function by monitoring the status of other plant proteins […]
Author: Masanori Izumi Affiliation: RIKEN Center for Sustainable Resource Science, Wako 351-0198, Japan masanori.izumi@riken.jp Autophagy is the ubiquitous process in eukaryotes leading to the degradation of intracellular components, during which a portion of the cytoplasm, including organelles, is sequestered by nascent autophagic membranes and delivered into the lytic organelles for degradation (Mizushima and Komatsu, 2011).

Iron is a cofactor of numerous plant proteins that function in processes ranging from redox reactions during photosynthesis to respiration. Typical soils contain approximately 1–5% iron, but much of this iron is not readily accessible to plants due to low solubility. Nongraminaceous plants help solubilize iron (Fe3+) in the soil by making the rhizosphere more […]
Maria Grazia Annunziata Max Planck Institute of Molecular Plant Physiology, 14476 Potsdam-Golm, Germany. ORCID ID: 0000-0001-8593-1741 By acting as redox regulatory factor, NADPH-dependent thioredoxin reductase C (NTRC) is involved in many metabolic processes as well as plastid biogenesis. It is the only isoform, out of three, localized to chloroplasts. Arabidopsis thaliana NTRC has been extensively […]
Molina-Contreras et al. show how differences in photoreceptors produce the differing shade responses of Arabidopsis and Cardamine. https://doi.org/10.1105/tpc.19.00275 by Sandi PAULIŠIĆ 1 and Jaime F. MARTINEZ-GARCIA 1,2 1, Centre for Research in Agricultural Genomics (CRAG) CSIC-IRTA-UAB-UB. 2, Institució Catalana de Recerca i Estudis Avançats (ICREA). Background: Plant development is strongly influenced by the proximity of […]
Nagashima et al. investigate molecular mechanisms for the sorting of a membrane protein KORRIGAN 1 (KOR1) in plant cells. Plant Cell https://doi.org/10.1105/tpc.19.00714 By Y. Nagashima1, and H. Koiwa1,2 1Vegetable and Fruit Improvement Center and Department of Horticultural Sciences, Texas A&M University 2Molecular and Environmental Plant Sciences, Texas A&M University Background: KORRIGAN1 (KOR1) is a membrane-bound […]
