MIR172 — Arabidopsis thaliana

Summary

AT2G28056, designated MIR172A, encodes a microRNA precursor that produces microRNA172. As a non-coding RNA, it does not encode a protein or enzyme. MIR172A is associated with the regulation of vegetative phase change, specification of floral organ identity, and photoperiodism and flowering. It has been linked to stem cell proliferation, root regeneration, leaf abscission, somatic embryogenesis, and response to UV-B and copper. The gene is connected to gene silencing by miRNA, miRNA transcription, and miRNA processing. Associations with agronomically relevant traits include seed weight, seed dormancy, fruit type and size, leaf length, leaf shape, leaf curling, stem elongation, sporogenesis, and floral organ identity. MIR172A is also linked to developmental processes, regeneration, abscission, and embryogenesis.
