Evolutionary, genetic, environmental and hormonal-induced plasticity in the fate of organs arising from axillary meristems in Passiflora spp.

► Formation of tendrils and flowers in Passiflora share common ontogenetic programs. ► Plasticity constraints the number of flowers and their distribution in relation to the tendril. ► This plasticity can be modulated by Cytokinins. ► This modulation allows changing the number of flowers in passion fruit.
