Nanoscale movements of cellulose microfibrils in primary cell walls ($)

/
Cell walls are complex mixtures of cellulose microfibrils, proteins and other materials. Their mechanical properties can be measured and modeled, but it is not always simple to translate these measurements to changes at the molecular level. Zhang et al. used atomic force microscopy to provide an unprecedented…

More Than Just a FAD(5): Unsaturated Fatty Acids in Chloroplasts Elicit Protective Autoimmunity

Arabidopsis (Arabidopsis thaliana) chloroplast-division mutants that have abnormally large chloroplasts have been around for quite some time, not only because they can be identified relatively easily through screening (Pyke & Leech 1991) and because their spectacular morphology sparks intrigue, but…

The Meaning of an End: N-terminal Acetyltransferase NAA50 Controls Plant Growth and Stress Responses

Author: Sjon Hartman ORCID: 0000-0002-6709-6436 Plant Ecophysiology, Institute of Environmental Biology, Utrecht University, Padualaan 8, 3584 CH, Utrecht, The Netherlands  At least 80% of eukaryotic proteins are estimated to undergo N-terminal acetylation (NTA), making it likely that your…

A novel regulator of stomatal immunity in tomato

Back to the Roots of Plant Immunity

Rich-Griffin et al. uncover cell type-specific gene networks that function in plant immunity in Arabidopsis roots. The Plant Cell (2020) https://doi.org/10.1105/tpc.20.00154   By Charlotte Rich-Griffin1, Ruth Eichmann1,2, Sascha Ott3,4,5 & Patrick Schäfer1,2  1School of Life Sciences,…

It takes two to be you: promoter motif pairs keep immune responses within cell identity boundaries

Being a multicellular organism is not an easy task. Proper functioning of individual cell types with different functions requires coordination of gene expression to determine cell identity, but also regulatory mechanisms to respond to environmental cues. The root may appear simple at first sight, but…

OsGSK2 integrates jasmonic acid and brassinosteroid signalling in rice

Plant defenses against herbivore or pathogen attack involve the coordination of multiple hormone-mediated signalling networks, including the jasmonate (JA) and brassinosteroid (BR) pathways. Jasmonate is an oxylipin phytohormone that triggers the transcription of defence-related proteins and secondary…

Remorins: essential regulators in plant–microbe interaction and cell death induction

Programmed cell death (PCD) is a genetically controlled process triggered by developmental or environmental cues. Plant–microbe interactions often lead to PCD in plant host cells, triggered by the hypersensitive response. Plants may recognize microbes through receptor-like kinases in the plasma membrane,…

NLR-Annotator: a tool for de novo annotation of intracellular immune receptor repertoire

Wei Zhang ORCID: 0000-0002-5092-643X Department of Plant Pathology, Kansas State University, 1712 Claflin Road, Throckmorton Hall, Manhattan, KS, 66506, USA weizhang17@ksu.edu Nucleotide-binding domain leucine-rich repeat (NLR) proteins serve as intracellular immune receptors in plants to…

Comparing genomes of diverse plants reveals new candidate genetic components for plant disease resistance
