Osa-miR7695 enhances transcriptional priming in defense responses against the rice blast fungus

MicroRNAs (miRNAs) are small non-coding RNAs that regulate gene expression at the posttranscriptional level in eukaryotes. In rice, MIR7695 expression is regulated by infection with the rice blast fungus Magnaporthe oryzae with subsequent down-regulation of an alternatively spliced transcript of natural resistanceassociated macrophage protein 6 (OsNramp6). NRAMP6 functions as an iron transporter in rice.
