Complete Genome Assembly of Pantoea stewartii subsp. stewartii DC283, a Corn Pathogen
نویسندگان
چکیده
The phytopathogen Pantoea stewartii subsp. stewartii DC283 causes Stewart's wilt disease in corn after transmission from the corn flea beetle insect vector. Here, we report that the complete annotated genome of P. stewartii DC283 has been fully assembled into one circular chromosome, 10 circular plasmids, and one linear phage.

A negative regulator mediates quorum-sensing control of exopolysaccharide production in Pantoea stewartii subsp. stewartii.
Classical quorum-sensing (autoinduction) regulation, as exemplified by the lux system of Vibrio fischeri, requires N-acyl homoserine lactone (AHL) signals to stimulate cognate transcriptional activators for the cell density-dependent expression of specific target gene systems. For Pantoea stewartii subsp. stewartii, a bacterial pathogen of sweet corn and maize, the extracellular polysaccharide ...
متن کاملBiological role of pigment production for the bacterial phytopathogen Pantoea stewartii subsp. stewartii.
Pantoea stewartii subsp. stewartii, the causal agent of Stewart's wilt of sweet corn, produces a yellow carotenoid pigment. A nonpigmented mutant was selected from a bank of mutants generated by random transposon mutagenesis. The transposon insertion site was mapped to the crtB gene, encoding a putative phytoene synthase, an enzyme involved in the early steps of carotenoid biosynthesis. We demo...

Pantoea stewartii subsp. stewartii is a bacterial phytopathogen that causes Stewart's wilt disease in corn. It uses quorum sensing to regulate expression of some genes involved in virulence in a cell density-dependent manner as the bacterial population grows from small numbers at the initial infection site in the leaf apoplast to high cell numbers in the xylem where it forms a biofilm. There ar...
متن کاملA single genetic locus in the phytopathogen Pantoea stewartii enables gut colonization and pathogenicity in an insect host.
Aphids are typically exposed to a variety of epiphytic and phytopathogenic bacteria, many of which have entomopathogenic potential. Here we describe the interaction between Pantoea stewartii ssp. stewartii DC283 (DC283), an enteric phytopathogen and causal agent of Stewart's wilt, and the pea aphid, Acyrthosiphon pisum. When ingested by aphids, DC283 establishes and aggregates in the crop and g...
متن کاملUnderstanding the Quorum-Sensing Bacterium Pantoea stewartii Strain M009 with Whole-Genome Sequencing Analysis
Pantoea stewartii is known to be the causative agent of Stewart's wilt, which usually affects sweet corn (Zea mays) with the corn flea beetle as the transmission vector. In this work, we present the whole-genome sequence of Pantoea stewartii strain M009, isolated from a Malaysian tropical rainforest waterfall.
