Starting Off Right: N-terminal Acetylation Stabilizes an Immune-activating Protein

Charles Copeland1 copeland@mpipz.mpg.de 1Department of Plant Microbe Interactions, Max Planck Institute for Plant Breeding Research, 50829 Cologne, Germany Plants rely on a complex innate immune system to recognize and respond to potential pathogens in their environment (Jones and Dangl, 2006). Activation of immune responses generally prevents infection; however, immune response activation is also detrimental for […]

Identifying and annotating mRNA transcripts from non-genic regions of the genome

Panda et al. use third-generation sequencing to examine the transcriptome of genomic regions that do not encode genes. Plant Cell https://doi.org/10.1105/tpc.20.00115  By Kaushik Panda – Donald Danforth Plant Science Center, and R Keith Slotkin – Donald Danforth Plant Science Center and University of Missouri Background: In spite of making up only a small percentage of […]

A novel role for a phospholipase D in plant immunity

By Marcelo Lattarulo Campos marcelolattarulo@ufmt.br Integrative Plant Research Laboratory, Departamento de Botânica e Ecologia, Instituto de Biociências, Universidade Federal de Mato Grosso, Cuiabá/MT, Brazil. A fundamental tenet of any immune system is the ability to detect the presence of harmful agents and then activate proper defense responses. In plants, the first layer of immunity is […]

Unregulated Sphingolipid Biosynthesis in Arabidopsis ORM Mutants

Gonzalez Solis et al. describe the metabolic, cellular, and physiological consequences of the complete loss of regulation of sphingolipid biosynthesis. Plant Cell https://doi.org/10.1105/tpc.20.00015  By Ariadna Gonzalez Solis and Edgar B. Cahoon  Background: Glycosphingolipids are molecules with backbones derived from serine and palmitoyl-CoA that are essential for endomembrane and plasma membrane function. The sphingolipid biosynthetic intermediates […]

Brassinosteroids Promote Greening of Etiolated Seedlings

Wang et al. demonstrate that BRs play important roles in seedling development and survival during the initial emergence of seedlings from subterranean darkness into sunlight. The Plant Cell (2020) https://doi.org/10.1105/tpc.20.00057. By Lingyan Wang,Yanchen Tian, Wen Shi, Min Fan and Ming-Yi Bai, The Key Laboratory of Plant Development and Environmental Adaptation Biology, Ministry of Education, School […]

Improving crop water-use efficiency requires optimizing the circadian clock

Meisha Holloway-Phillips Department of Environmental Sciences, University of Basel, Switzerland m.holloway-phillips@unibas.ch The slogan, ‘more crop per drop’, which was popularised in the early 2000s, depicts the need to improve the productivity of crops for the same water inputs (Kijne et al., 2003). Whilst the approaches by which this could be achieved have evolved and expanded, […]

NIT proteins regulate rice root plasticity in response to nitrate and ammonium

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 […]

2-in-1-GEFIs: Biosensors for two plant signals at one time

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 […]

From fuzz to fiber – identification of genes involved in cotton fiber elongation

Kim L Johnson La Trobe Institute for Agriculture & Food, Department of Animal, Plant and Soil Sciences, La Trobe University, Bundoora, Victoria 3086, Australia Email: k.johnson@latrobe.edu.au At least some of the clothing you are wearing is likely made of cotton, and you are not alone. Cotton is currently the most common textile fiber used worldwide, […]
