A structurally dynamic chromosome 11 locus from Oryza rufipogon L. confers broad-spectrum recessive resistance to bacterial blight

In this study, the wild rice accession Oryza rufipogon Wild173 (UP36) exhibiting strong resistance to multiple Xoo strains was investigated in comparison with the susceptible rice cultivar Longjing-31 (CK2). To explore the molecular mechanisms underlying bacterial blight resistance, transcriptome sequencing (RNA-seq) was performed on leaf tissues collected from resistant and susceptible plants following inoculation with the Xoo strain PXO99A.

Comparative transcriptomic analysis was conducted to identify differentially expressed genes associated with defense responses. The dataset provides insights into transcriptional reprogramming during pathogen infection and facilitates the identification of candidate genes and defense-related pathways involved in bacterial blight resistance in rice. These data provide valuable resources for understanding host–pathogen interactions and for improving disease resistance in rice breeding programs.
