Metabolic signals orchestrate plant defenses against microbial pathogen invasion. Here, we report the identification of non-protein amino acid pipecolic (Pip), a common Lys catabolite in plants and animals, as critical regulator inducible immunity. Following recognition, Pip accumulates inoculated Arabidopsis thaliana leaves, leaves distal from site inoculation, and, most specifically, petiole exudates leaves. Defects mutants AGD2-LIKE DEFENSE RESPONSE PROTEIN1 (ALD1) systemic acquired...
Ensembl (www.ensembl.org) is a database and genome browser for enabling research on vertebrate genomes. We import, analyse, curate integrate diverse collection of large-scale reference data to create more comprehensive view biology than would be possible from any individual dataset. Our extensive resources include evidence-based gene regulatory region annotation, variation trees. An accompanying suite tools, infrastructure programmatic access methods ensure uniform analysis distribution all...
Abstract We investigated the relationships of two immune-regulatory plant metabolites, salicylic acid (SA) and pipecolic (Pip), in establishment systemic acquired resistance (SAR), SAR-associated defense priming, basal immunity. Using SA-deficient sid2, Pip-deficient ald1, sid2 ald1 plants deficient both SA Pip, we show that Pip act independently from each other synergistically Arabidopsis thaliana immunity to Pseudomonas syringae. Transcriptome analyses reveal SAR is characterized by a...
The nonprotein amino acid pipecolic (Pip) regulates plant systemic acquired resistance and basal immunity to bacterial pathogen infection. In Arabidopsis (Arabidopsis thaliana), the lysine (Lys) aminotransferase AGD2-LIKE DEFENSE RESPONSE PROTEIN1 (ALD1) mediates pathogen-induced accumulation of Pip in inoculated distal leaf tissue. Here, we show that ALD1 transfers α-amino group l-Lys acceptor oxoacids. Combined mass spectrometric infrared spectroscopic analyses vitro assays extracts...
Germin-like proteins (GLPs) are defined by their sequence homology to germins from barley and present ubiquitously in plants. Analyses of corresponding genes have revealed diverse functions GLPs plant development biotic abiotic stresses. This study describes the identification a family 14 germin-like Brassica napus (BnGLP) designated BnGLP1-BnGLP14 investigated potential BnGLPs defense against necrotrophic fungus Sclerotinia sclerotiorum. Sequence alignment phylogenetic analyses classify...
