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...

Increased yields of L-asparaginase from Erwinia aroideae NRRL B-138 were obtained by medium enrichment techniques coupled with aeration optimization.

Erwinia-like microorganisms were isolated from the vital organs of more than 40% of a large deer population examined as well as from 13% of a small random sampling. Over a brief period of observation, a similar isolate was recovered from throat cultures of two children and one adolescent. There is no obvious explanation of the presence of the plant pathogen or its significance under these circu...

"Candidatus Erwinia dacicola" is a Gammaproteobacterium that forms a symbiotic association with the agricultural pest Bactrocera oleae Here, we present a 2.1-Mb draft hybrid genome assembly for "Ca. Erwinia dacicola" generated from single-cell and metagenomic data.

Abstract Stalk rot disease, which can be caused by fungi and bacteria, is a common problem in maize cultivation. The infection of the disease started 2019 Tanah Laut Regency with an attack area 4.7 hectares. increased to 27.5 hectares 2020. This study aimed identify causal agent stem how it spread throughout regency. identification pathogen field. result showed that stalk was Pythium Fusarium g...

A DNA marker that distinguishes plant associated bacteria at the species level and below was derived by comparing six sequenced genomes of Xanthomonas, a genus that contains many important phytopathogens. This DNA marker comprises a portion of the dnaA replication initiation factor (RIF). Unlike the rRNA genes, dnaA is a single copy gene in the vast majority of sequenced bacterial genomes, and ...

Abstract Pineapple plants (hybrid MD2) with bacterial heart rot were detected in a commercial plantation at Glasshouse Mountains, Queensland, November 2015. The strain BRIP64263 isolated from infected tissue was shown to be Gram negative soft-rotting bacterium capable of growth 41 ºC, and based on its culture properties provisionally identified as Dickeya . This compared other putative strains ...

We have investigated the role of bacterial resistance to oxidative stress in pathogenesis. The oxyR gene from the pathogenic bacterium Erwinia chrysanthemi has been characterized. It is closely related to that found in Escherichia coli (88% overall amino acid identity). An E. chrysanthemi oxyR mutant strain was constructed by marker exchange. After induction with a sublethal dose of H202, this ...
