Mutations of ousA Alter the Virulence of Erwinia chrysanthemi

open access: yesMolecular Plant-Microbe Interactions, 2005
A negative correlation was observed between the aggressiveness of several Erwinia chrysanthemi strains on potato tuber and their osmotic tolerance. The disruption of the ousA gene encoding the major osmoprotectant uptake system highly enhanced bacterial ...

The MarR Family Transcriptional Regulator EmrR Negatively Regulates the Type III Secretion System (T3SS) and Positively Modulates Pathogenicity in Dickeya oryzae

open access: yesMolecular Plant Pathology, Volume 27, Issue 4, April 2026.
This study revealed that the transcriptional regulator EmrR in Dickeya oryzae modulates virulence by regulating hrpL expression and c‐di‐GMP levels. It affects motility, biofilm formation, cellulase production and pathogenicity. EMSA and footprinting confirmed EmrR binds directly to the promoter of its target operon.

Production, characterization and bioinformatics analysis of l-asparaginase from a new Stenotrophomonas maltophilia EMCC2297 soil isolate

open access: yesAMB Express, 2020
An exhaustive screening program was applied for scoring a promising l-asparaginase producing-isolate. The recovered isolate was identified biochemically and molecularly and its l-asparaginase productivity was optimized experimentally and by Response ...

The Role of Several Multidrug Resistance Systems in Erwinia chrysanthemi Pathogenesis

open access: yesMolecular Plant-Microbe Interactions, 2006
The role of several multidrug resistance (MDR) systems in the pathogenicity of Erwinia chrysanthemi 3937 was analyzed. Using the blast algorithm, we have identified several MDR systems in the E.

Evaluation of Characteristics and Ethnic Sensitivity for FDA‐Approved Drugs with Racial and Ethnic Differences in Pharmacokinetics, Safety, and Efficacy

open access: yesThe Journal of Clinical Pharmacology, Volume 65, Issue 11, Page 1381-1391, November 2025.
Abstract Racial and ethnic differences in drug disposition and response may have a significant impact on its risk‐benefit balance. Therefore, it is important to examine whether an investigational drug has characteristics that make the pharmacokinetics (PK), safety, and efficacy likely to be affected by intrinsic and extrinsic ethnic factors based on ...
