Integrative transcriptome meta-analysis distinguishes compatibility and incompatibility in rice-Xanthomonas interaction.

Early abscisic-acid biosynthesis and signaling activation distinguishes compatible rice–Xanthomonas oryzae interactions, while susceptibility is linked to extensive transcriptional plasticity.

• Why it matters: Resistance versus susceptibility in the rice–Xanthomonas pathosystem is still not fully explained at the transcriptional level, especially over time.
• What they did: The authors performed a systems-level meta-analysis of 100+ public rice–Xanthomonas transcriptome datasets using stringent filtering and metadata integration to resolve temporal gene-function patterns.
• The result: Compatible interactions show early abscisic-acid pathway activation and susceptibility-associated plasticity, and candidate infection-responsive genes (OsJAZ11, OsSYP131b, OsMYB45) modestly increased defense expression and reduced lesion length in rice leaves.
