Context
Rice is both a staple crop and a model system for understanding how plants balance growth, stress response, and disease resistance. Xanthomonas oryzae causes bacterial blight, one of the most destructive rice diseases worldwide. Drought stress triggers reactive oxygen species (ROS) signaling pathways that can interact — sometimes antagonistically — with immune responses to pathogens.
Question
How does drought-induced ROS regulation affect rice resistance to Xanthomonas oryzae infection, and what molecular crosstalk links abiotic and biotic stress pathways?
Method
The project examined ROS dynamics under drought conditions, measured pathogen susceptibility and defense marker expression following X. oryzae challenge, and analyzed how drought-primed ROS signaling altered downstream resistance phenotypes in rice plants.
Result
Findings suggest meaningful crosstalk between drought-induced ROS regulation and bacterial blight resistance — drought stress can modulate defense responses in ways that either prime or compromise pathogen resistance depending on timing and severity.
Reflection
Crop resilience is never a single-axis problem. Understanding how drought and disease pathways interact is essential for breeding rice varieties that survive both climate stress and pathogen pressure.
