Conserved Function of FLOWERING LOCUS T (FT) Homologues As Signals for Storage Organ Differentiation

•FT-like proteins trigger storage organ formation in different species.•Allelic variants of the StCDF1 gene are involved in potato domestication.•miR156 and miR172 are regulators of tuber formation and development.•Cytokinins, auxins and gibberellins play a crucial role in tuberization.•Similar hormonal balances control axillary meristem activation and tuber induction.
