Background. Ralstonia solanacearum is an economically important plant pathogen with an
unusually large host range. The Moko (banana) and NPB (not pathogenic to banana) strain
groups are closely related but are adapted to distinct hosts. Previous comparative genomics
studies uncovered very few differences that could account for the host range difference
between these pathotypes. To better understand the basis of this host specificity, we used
RNAseq to profile the transcriptomes of an R. solanacearum Moko strain and an NPB strain …
