An intron-split microRNA mediates cleavage of the mRNA encoded by low phosphate root in Solanaceae.

ABSTRACT:

Main conclusion

A microRNA with a non-canonical precursor structure harbours an intron in between its miRNA-5p and miRNA-3p relevant for its biogenesis, is conserved across Solanaceae, and targets the mRNA of low phosphate root. Hundreds of miRNAs have been identified in plants and great advances have been accomplished in the understanding of plant miRNA biogenesis, mechanisms and functions. Still, many miRNAs, particularly those with less conventional features, remain to be discovered. Likewise, additional layers of regulation from miRNA generation to action and turnover are still being revealed. The current study describes a microRNA not previously identified given its unusual intron-split stem-loop structure, that has been previously observed only within the monocot-specific miR
