Citrus plants are challenged by a broad diversity of abiotic and biotic stresses, which
definitely alter their growth, development, and productivity. In order to survive the various …

Huanglongbing is causing economic devastation to the citrus industry in Florida, and
threatens the industry everywhere the bacterial pathogens in the Candidatus Liberibacter …

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 …

In this study with the model organism Agrobacterium tumefaciens, we used a combination of
lacZ gene fusions, reverse transcriptase PCR (RT-PCR), and deletion and insertional …

Genome sequence analyses of bacterial plant pathogens are revealing important insights
into the molecular determinants of pathogenicity and, through transcript characterization …

Sigma54 (σ54) regulates nitrogen and carbon utilization in bacteria. Promoters that are σ54-
dependent are highly conserved and contain short sequences located at the− 24 and− 12 …

The alternative sigma factor σ54 has been shown to regulate the expression of a wide array
of virulence-associated genes, as well as central metabolism, in bacterial pathogens. In …

Transcription initiation by bacterial σ 54-polymerase requires the action of a transcriptional
activator protein. Activators bind sequence-specifically upstream of the transcription initiation …

Bacterial plant pathogens rely on a battalion of transcription factors to fine-tune their
response to changing environmental conditions and to marshal the genetic resources …

Temperature plays an important role in the heap bioleaching. The maldistribution of
ventilation in the heap leads to local hyperthermia, which does exert a tremendous stress on …
