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

/in , , /by

Wei Zhang ORCID: 0000-0002-5092-643X Department of Plant Pathology, Kansas State University, 1712 Claflin Road, Throckmorton Hall, Manhattan, KS, 66506, USA [email protected] Nucleotide-binding domain leucine-rich repeat (NLR) proteins serve as intracellular immune receptors in plants to recognize different types of effectors delivered by pathogens from all kingdoms. NLR genes form the largest plant disease resistance (R) […]

Too Active in ER Fusion? Here Comes LUNAPARK to the Rescue

/in , , /by

Sun et al. found that Arabidopsis LUNAPARK, a protein evolutionarily conserved in eukaryotes, is an E3 ligase that promotes the degradation of ROOT HAIR DEFECTIVE3, an ER fusogen.

Mix, Match, and Maize: A Synthetic System for Maize Nuclear Auxin Response Circuits

/in , , /by

Dhineshkumar Thiruppathi 1,2  ORCID ID: 0000-0002-2018-3356 Donald Danforth Plant Science Center, Saint Louis, Missouri 63132 1Lead author 2Author for contact: [email protected] The phytohormone auxin plays a major part in nearly every plant process, including growth and development. Auxin performs these functions, in part, by eliciting context-specific nuclear responses mediated by a signaling network (Leyser, 2018). […]

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

/in , , /by

Charles Copeland1 [email protected] 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

/in , , /by

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

/in , /by

By Marcelo Lattarulo Campos [email protected] 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

/in , , /by

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 […]
