Schematic illustrating the model by which ethylene and ABA regulate fruit ripening via EBF1 and ABI5-like. Adapted from Song et al. (2021). Expression of MaEBF1 and MaABI5-like increases during ripening but can be suppressed by chilling. MaEBF1- and MaABI5-like proteins physically interact and MaABI5-like can bind to ABRE elements in promoter regions. The proteins increase transcription of starch and cell wall degradation enzymes to promote fruit ripening.
