Gene Details:

• MSU gene ID: None
• RAPdb gene ID: None
• Gene Symbol: Osa-miR162a
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• Osa-miR162a fine-tunes rice resistance to Magnaporthe oryzae and Yield.
• Overexpression of Osa-miR162a enhances rice resistance to M.
• Moreover, the transgenic lines overexpressing Osa-miR162a display decreased seed setting rate resulting in slight reduced yield per plant, whereas the transgenic lines blocking Osa-miR162 show an increased number of grains per panicle, resulting in increased yield per plant.
• In contrast, blocking Osa-miR162 by overexpressing a target mimic of Osa-miR162a enhances susceptibility to blast fungus associating with compromised induction of defense-related gene expression and H2O2 accumulation.
• Here we demonstrate that Osa-miR162a fine-tunes rice immunity against M.
• Together, our results indicate that Osa-miR162a is involved in rice immunity against M.
• Consistently, overproduced Osa-miR162a in transgenic rice plants compromised the fecundity of BPH adults fed with these plants, but meanwhile perturbed root and grain development.
• Overexpression of an Osa-miR162a Derivative in Rice Confers Cross-Kingdom RNA Interference-Mediated Brown Planthopper Resistance without Perturbing Host Development.
