Model of the study showing the C-terminal region of miPEP858a can enhance the expression of precursor and mature miR858a similar to full-length miPEP858a providing evidence regarding the importance of amino acids present at the C-terminal end. The C-terminal peptides have the potential to regulate phenylpropanoid pathway genes, and metabolites along with plant growth and development. The activation and inactivation of transcription are depicted by arrows and inverted T, respectively. Tick mark shows binding on promoter and have regulatory effect, while cross symbol shows no binding on promoter and do not have regulatory effect.
