CC   -!- FUNCTION: Regulatory peptide encoded by the primary transcript (pri-
CC       miR171b) of the microRNA miR171b that enhances the accumulation of its
CC       corresponding mature miRNA. Acts probably as a transcriptional
CC       activator of its corresponding pri-miRNA. Has no effect on the
CC       accumulation of other miRNAs. Addition of synthetic miPEP171b increases
CC       the abundance of miR171b, with consequent reduction of lateral root
CC       formation. {ECO:0000269|PubMed:25807486}.
CC   -!- TISSUE SPECIFICITY: Lateral root initiations.
