Transcriptional profile of P. syringae pv. phaseolicola NPS3121 at low temperature: physiology of phytopathogenic bacteria.

ABSTRACT:

Background

Low temperatures play key roles in the development of most plant diseases, mainly because of their influence on the expression of various virulence factors in phytopathogenic bacteria. Thus far, studies regarding this environmental parameter have focused on specific themes and little is known about phytopathogenic bacteria physiology under these conditions. To obtain a global view regarding phytopathogenic bacteria strategies in response to physiologically relevant temperature changes, we used DNA microarray technology to compare the gene expression profile of the model bacterial pathogen P. syringae pv. phaseolicola NPS3121 grown at 18°C and 28°C.

Results

A total of 236 differentially regulated genes were identified, of which 133 were up-regulated and 103 were do
