Role of phasiRNAs from two distinct phasing frames of GhMYB2 loci in cis- gene regulation in the cotton genome

Background Phased small interfering RNA (phasiRNA) is primarily derived from the 22-nt miRNA targeting loci. GhMYB2 , a gene with potential roles in cotton fiber cell fate determination, is a target gene of miR828 and miR858 in the generation of phasiRNAs. Results In the presented work, through the evaluation of phasing scores and phasiRNA distribution pattern, we found that phasiRNAs from GhMYB2 were derived from the 3′ cleavage fragments of...
