Plants have three main phases in their life cycle: juvenile, adult vegetative and reproductive. The transition to the reproductive stage, when flowering occurs, has been widely studied in model species. However, the transition from the juvenile to the adult vegetative stages needs to be better understood, especially at the molecular level. Most of the phase transition studies in the literature were performed with the model species Arabidopsis thaliana, but there is a need to understand how these processes occur in other species. The species of the genus Passiflora are excellent models for studies of plant development, as there are evident morphological differences between plants in the juvenile, vegetative adult and reproductive stages. In Passiflora there are no tendrils in the juvenile stage. In the vegetative adult stage, tendrils appear from the leaf axillary meristems, and in the reproductive stage, flowers appear simultaneous to tendrils, in the leaf axils. It is known that phytohormones directly influence plant development, especially cytokinins and gibberellins. In the present study we had as goals: a) to evaluate the influence of the exogenous application of cytokinin and gibberellin in P. organensis during the transition from the juvenile to the vegetative adult phase; b) identify and characterize possible orthologs of genes involved in metabolism, signaling and response to cytokinins and gibberellins in Passiflora; and c) characterize the expression pattern of genes related to gibberellins. The application of cytokinin repressed the development of tendrils, stimulated the development of vegetative branches from the axillary meristems, in addition to causing morphological changes in the leaves, such as the development of lobes and deformities, when at higher doses. On the other hand, the application of gibberellin stimulated the early development of tendrils, accelerated plant growth and morphological changes in leaves that showed early adult characteristics. Genes related to synthesis, degradation and response to cytokinins and gibberellins were characterized. Most of the P. organensis orthologs showed great sequence similarity with other species, suggesting functional similarity.We analyzed the expression of genes related to synthesis, catabolism and response to gibberellins in P. edulis plants submitted to exogenous gibberellin, GA 3 , and also in plants submitted to paclobutrazol applications. Gene expressions changed in order to balance gibberellin concentrations in plants, as reported in the literature. The results obtained can be applied to future studies of genetic breedingh both in species of the genus Passiflora with commercial interest, as in other species.
