Global transcriptome profiling after exposure to solute, matric, and sand desiccation stress in S. wittichii RW1

ABSTRACT: Spingomonas wittichii strain RW1 can completely oxidize dibenzo-p-dioxins and dibenzofurans, which are persistent contaminants of soils and sediments. For successful application in soil bioremediation systems, strain RW1 must cope with fluctuations in water availability, or water potential. The objectives of this study were to characterize how strain RW1 responses to changes in different components of the total water potential (solute and matric potential) and to then connect these responses to more realistic scenarios of soil desiccation. To accomplish this task, transcriptome profiling was used to investigate the effects of decreasing the solute potential with sodium chloride (solute stress), decreasing the matric potential with high-molecular weight polyethylene glycol (matric stress),
