Quantitative Methods to Assess Differential Susceptibility of Arabidopsis thaliana Natural Accessions to Dickeya dadantii
Among the most devastating bacterial diseases of plants, soft rot provoked by Dickeya spp. cause crop yield losses on a large range of species with potato being the most economically important. The use of antibiotics being prohibited in most countries in the field, identifying tolerance genes is expected to be one of the most effective alternate disease control approaches. A prerequisite for th...
متن کاملSlyA, a MarR family transcriptional regulator, is essential for virulence in Dickeya dadantii 3937.
SlyA, a MarR family transcriptional regulator, controls an assortment of biological functions in several animal-pathogenic bacteria. In order to elucidate the functions of SlyA in the phytopathogen Dickeya dadantii (formerly Erwinia chrysanthemi) 3937, a slyA gene deletion mutant (denoted DeltaslyA) was constructed. The mutant exhibited increased sensitivity to sodium hypochlorite, the cationic...
متن کاملThe flagellar sigma factor fliA is required for Dickeya dadantii virulence.
The genome sequence of the Enterobacteriaceae phytopathogen Dickeya dadantii (formerly Erwinia chrysanthemi) revealed homologs of genes required for a complete flagellar secretion system and one flagellin gene. We found that D. dadantii was able to swim and swarm but that ability to swarm was dependent upon both growth media and temperature. Mutation of the D. dadantii fliA gene was pleiotropic...
متن کاملEffector recognition and activation of the Arabidopsis thaliana NLR innate immune receptors.
Plant immunity to coevolved pathogens relies on the perception of pathogenic effectors by nucleotide-binding domain and leucine-rich repeat-containing (NLR) proteins-sophisticated intracellular receptors that have both perception and signaling roles in activating defenses. Given the conserved domain architecture of NLRs, a structural biology perspective is particularly relevant to understanding...
متن کاملPhoP-PhoQ Two-Component System Required for Colonization Leading to Virulence of Dickeya dadantii 3937 in planta
Dickeya dadantii (formerly Erwinia chrysanthemi, Pectobacterium chrysanthemi) is a necrotrophic, intracellular, plant pathogenic enterobacterium that induces soft rot diseases on a great variety of plants worldwide by secreting mainly multiple plant cell wall-degrading enzymes including pectinases, cellulases and proteases1. Additional factors that contribute to its pathogenicity are exopolysac...
