Identification of a putative alternate sigma factor and characterization of a multicomponent regulatory cascade controlling the expression of Pseudomonas syringae pv. syringae Pss61 hrp and hrmA genes
TLDR
The results indicate that hrpRS and hrpL are part of a regulatory cascade in which HrpR and HrPS activate expression of hrPL and HRpL, a putative sigma factor, induces expression of HrnPL-responsive genes.
Combined effect of ultrasound and organic acids to reduce Escherichia coli O157:H7, Salmonella Typhimurium, and Listeria monocytogenes on organic fresh lettuce.
TLDR
The combined treatment of ultrasound with organic acids was effective at increasing pathogen reduction compared to individual treatments without significantly affecting quality, and demonstrates its potential as a novel method to increase the microbial safety on organic fresh lettuce.
A comprehensive expression analysis of the WRKY gene superfamily in rice plants during defense response
TLDR
The expression profiles suggest that a large number of WRKY DNA-binding proteins are involved in the transcriptional activation of defense-related genes in response to rice pathogens.
Characterization and Comparative Genomic Analysis of a Novel Bacteriophage, SFP10, Simultaneously Inhibiting both Salmonella enterica and Escherichia coli O157:H7
TLDR
This is the first report identifying specific infection and inhibition of Salmonella Typhimurium and E. coli O157:H7 by a single bacteriophage, implying that the genes are major host specificity determinants.
Prevalence, genetic diversity, and antibiotic resistance patterns of Campylobacter jejuni from retail raw chickens in Korea.
TLDR
The results show that the genetic diversity of C. jejuni isolates is very high and the correlation between genotype and antibiotic resistance was low even though many bacteria showed multi-drug resistance.
Organization and environmental regulation of the Pseudomonas syringae pv. syringae 61 hrp cluster
TLDR
The results indicate that enhanced expression of hrp genes occurs early in the interaction with nonhost plant species in an apparent response to altered nutritional conditions.
Characterization of LysB4, an endolysin from the Bacillus cereus-infecting bacteriophage B4
TLDR
LysB4 is believed to be the first reported L-alanoyl-D-glutamate endopeptidase of this type to target B. cereus-infecting bacteriophages and a good candidate as a biocontrol agent against B. Cereus and other pathogenic bacteria.

TLDR
The hydrolysis and transglycosylation properties of AmyM suggest that it has novel characteristics and can be regarded as an intermediate type of maltogenic amylase, α-amyl enzyme, and 4-α-glucanotransferase.
Dynamics of Xanthomonas oryzae pv. oryzae Populations in Korea and Their Relationship to Known Bacterial Blight Resistance Genes.
TLDR
It is concluded that the pyramid line containing genes Xa4, xa5, and Xa21 would be the most promising and valuable genotype for improving Korean japonica cultivars for BB resistance.
Prevalence and genetic diversity of Enterobacter sakazakii in ingredients of infant foods.
TLDR
The analysis of E. sakazakii isolates using PFGE, RAPD, and the antibiotic resistance test identified 18 composite types from 113 isolates, suggesting diverse sources of contamination.
