(Submitter supplied) This microarray experiment is part of a study addressing the importance of glutamine metabolism in Streptococcus pneumoniae for the virulence of this bacterium. To be able to gain more insight into the phenotype of a double mutant of glnA (TIGR 4 locus tag SP0502, encoding glutamine synthetase) and glnP (SP1241, encoding a permease component of a glutmine uptake ABC transporter), the transcriptome of this mutant, the glnPA double mutant, was determined in strain S. more...

(Submitter supplied) Plant pathogens can cause serious diseases that impact global agriculture1. Understanding how the plant immune system naturally restricts pathogen infection holds a key to sustainable disease control in modern agricultural practices. However, despite extensive studies into the molecular and genetic basis of plant defense against pathogens since the 1950s2,3, one of the most fundamental questions in plant pathology remains unanswered: how resistant plants halt pathogen growth during immune activation. more...

(Submitter supplied) Xylella fastidiosa regulates traits important to both virulence of grape as well as colonization of sharpshooter vectors via its production of a fatty acid signal molecule known as DSF whose production is dependent on rpfF. While X. fastidiosa rpfF mutants exhibit increased virulence to plants they are unable to be spread from plant to plant by insect vectors. To gain more insight into the traits that contribute to these processes, a DNA microarray for this species was designed and utilized to determine the RpfF-dependent regulon by transcriptional profiling. more...

(Submitter supplied) We conducted genome-wide microarray analyses to determine the regulons of RcsB and RcsC in liquid medium and, for the first time, on immature pear fruit. Our array analyses identified a total of 648 genes differentially regulated by the RcsCB in vitro and in vivo. Consistent with our previous findings, RcsB acts as a positive regulator in both conditions, while RcsC positively controls amylovoran biosynthetic gene expression in vivo, but negatively in vitro. more...
