SUMOylation and the Regulation of Aluminum Resistance

Fang and Zhang et al. show that SUMOylation and deSUMOylation regulate the stability of a transcription factor, thereby influencing aluminum resistance in Arabidopsis. Descriptive paragraph. Plant Cell https://doi.org/10.1105/tpc.20.00687 Background: Aluminum (Al) is a primary constraint for crop production on acid soils, which make up more than 30% of the arable land in the world. Plants […]

On how to build a larger and healthier Arabidopsis ROSette using a mitochondrial protein (spoiler: reactive oxygen species)

Javier Edgardo Moreno ORCID ID: 0000-0001-9763-5325 Twitter: @JaviMorenoOK Instituto de Agrobiotecnología del Litoral (UNL-Conicet), Facultad de Bioquímica y Ciencias Biológicas, Universidad Nacional del Litoral Santa Fe 3000, Argentina   Cellular respiration is at the core of central metabolism, generating energy out of simple hydrocarbon molecules. This energy runs fundamental functions of the cell. A collateral […]

Persulfidation of ATG4 negatively regulates autophagy

Ana M. Laureano-Marín, Ángeles Aroca, et al. explore the role of persulfidation in the regulation of autophagy. Plant Cell https://doi.org/10.1105/tpc.20.00766  by Cecilia Gotor, Ana M. Laureano-Marín, Ángeles Aroca Instituto de Bioquímica Vegetal y Fotosíntesis, Consejo Superior de Investigaciones Científicas and Universidad de Sevilla, Seville, Spain   Background: Hydrogen sulfide (H2S) is a poisonous substance hazardous […]

Callose deposition during pollen development

Madeleine Seale University of Oxford maddy.seale@plants.ox.ac.uk Callose is a cell wall component that is dynamically deposited and degraded during pollen development. Thanks to a new paper investigating pollen formation in cotton (Gossypium hirsutum), we now know that a pollen-specific protein regulates callose deposition by inhibiting the action of a transcription factor, WRKY15 (Li et al., […]

Getting to the Root of Plant Morphometrics, one DEEP Picture at a Time

Hüther et al. develop a new pipeline to extract phenotypic traits from plant pictures with minimal supervision from the user. The Plant Cell (2020) https://doi.org/10.1105/tpc.20.00318 By Patrick Hüther, Niklas Schandry, Katharina Jandrasits, Ilja Bezrukov and Claude Becker Background: To understand the function of a gene, we need to be able to link genetic information and […]

Surprise –salicylic acid receptors can do so much!

Liu et al. investigate the diverse roles of the salicylic acid receptors NPR1, NPR3 and NPR4 in local and long-range plant immunity. The Plant Cell (2020).  https://doi.org/10.1105/tpc.20.00499 By Yanan Liu1,2, Tongjun Sun2,3 and Yuelin Zhang2 (1 College of Bioscience and Biotechnology, Hunan Agricultural University, Changsha, China;2 Department of Botany, University of British Columbia, Vancouver, BC, […]

How circadian changes in metabolism affect hybrid vigor

Zhi Li, Andan Zhu, et al. compare inbred and hybrid lines to explore how daily changes in metabolic pathways affect hybrid vigor. The Plant Cell https://doi.org/10.1105/tpc.20.00320  Background: Heterosis or hybrid vigor refers to the superior growth or fitness in the hybrid progeny compared to one or both parents. Heterosis is widespread and commonly used in […]

In a nutshell: Finally connecting PI3P to autophagy and endosomal sorting

Liu et al., generate a novel collection of mutants impaired in PI3P biosynthesis and discovered new features and functions of this phosphoinositide in intracellular trafficking. The Plant Cell (2020). https://doi.org/10.1105/tpc.20.00285 By Richard S. Marshall and Richard D. Vierstra, Washington University, Saint Louis, USA Background Phosphoinositide lipids are key determinants for intracellular trafficking and membrane/organelle identity, […]
