Mango (Mangifera indica L.), as a typical climacteric fruit, undergoes ripening and senescence processes closely related to ethylene. Ethylene-responsive factors (ERF) play crucial roles in plant growth, fruit ripening and ethylene signaling transduction. Mango variety Guifei was used, MiERF20, 492 bp long and encoding 163 amino acids, was cloned and analyzed. Bioinformatics analysis revealed that MiERF20 was an unstable, hydrophilic protein without signal peptides or transmembrane regions, containing 25 phosphorylation sites and one AP2 conserved domain. The secondary structure was dominated by 40.49% irregular coils, 33.13% α-helices, 16.56% extensions and 9.82% β-rotations. Its secondary structure comprised irregular coils, α-helices, extended chains, and β-turns, consistent with AP2 domain features. MiERF20 showed 83.89% homology with ERF20 of Lacertidae pistachio. Subcellular localization indicated that MiERF20 was located in the nucleus and possessed transcriptional activation activity. Prokaryotic expression assays demonstrated that the protein could be inducibly expressed in a prokaryotic system. Real-time fluorescence quantification showed that MiERF20 was ethylene-inducible, suggesting its role in ethylene-regulated fruit ripening. This study would provide a foundation for further analysis of the functions and regulatory mechanisms of ERF transcription factors during postharvest fruit ripening.
