Comparative transcriptome profiling of a rice line carrying Xa39 and its parents triggered by Xanthomonas oryzae pv. oryzae provides novel insights into the broad-spectrum hypersensitive response.

Background: Bacterial blight, caused by Xanthomonas oryzae pv. oryzae (Xoo), is a devastating rice disease worldwide. Xa39 is a resistance (R) gene with a broad-spectrum hypersensitive response (BSHR) to Xoo.
