Hypothesis
Can a new gene in rice evolve de novo to enhance disease resistance?
Conclusion
The study found that the OsDR10 gene negatively regulates rice's defense response to pathogens, and its suppression enhances resistance.
Supporting Evidence
- OsDR10 suppression led to enhanced resistance against multiple strains of Xanthomonas oryzae.
- Transgenic plants with suppressed OsDR10 showed significantly reduced lesion areas after pathogen infection.
- Lower levels of OsDR10 transcripts were associated with increased disease resistance.
Takeaway
Scientists discovered a new gene in rice that helps the plant fight off diseases. When they turned off this gene, the rice plants became better at resisting infections.
Methodology
The researchers used RNA interference to suppress the OsDR10 gene in rice and analyzed the resulting disease resistance.
Participant Demographics
The study involved various rice lines, including both resistant and susceptible cultivars.
