The only species in the genus Passiflora (Passifloraceae) known to produce resin glands is P. foetida. These glands are secretory trichomes mainly present on the floral bracts and leaf stipules. The secretion produced by these glands has received attention recently due to the presence of substances with pharmacological properties. Attempts to apply in vitro cell culture methods for the large scale production of highly valuable metabolites has been rather limited due to the fact that these compounds are produced by highly differentiated secretory cells in trichomes which are seldom obtained or because differentiation is inhibited by in vitro conditions. Here we describe the in vitro plant regeneration of P. foetida obtained via organogenesis, using mature zygotic embryos as explants. Differentiated plantlets and, more important, the de novo differentiation of secretory trichomes in vitro could be observed in less than 30 days. There was a clear effect of the concentration of 2,4-dichlorophenoxyacetic acid in the culture media on the regeneration of plants and on the differentiation of glandular trichomes. Our results should be useful for the micropropagation of P. foetida, as well as for studies of the process of secretory trichome differentiation and the implemention of biotechnological methodologies for in vitro mass production of passifloricin and/or other substances present in the P. foetida resin. © 2011 Springer Science+Business Media B.V.10819199Agrawal, A.A., Induced responses to herbivory and increased plant performance (1998) Science, 279, pp. 1201-1202Bandyopadhyay, T., Gangopadhyay, G., Poddar, R., Mukherjee, K.K., Trichomes: their diversity distribution and density in acclimatization of teak (Tectona grandis L.) plants grown in vitro (2004) Plant Cell Tiss Organ Cult, 78, pp. 113-121Becerra, D.C., Forero, A.P., Góngora, G.A., Age and physiological condition of donor plants affect in vitro morphogenesis in leaf explants of Passiflora edulis f. flavicarpa (2004) Plant Cell Tissue Organ Cult, 79, pp. 87-90Bonfill, M., Mangas, S., Moyano, E., Cusido, R.M., Palazón, J., Production of centellosides and phytosterols in cell suspension cultures of Centella asiatica (2011) Plant Cell Tiss Organ Cult, 104, pp. 61-67Braglia, L., de Benedetti, L., Giovannini, A., Nicoletti, F., Bianchini, C., Pepino, L., Mercuri, A., In vitro plant regeneration as a tool to improve ornamental characters in Passiflora species (2010) Acta Hortic, 855, pp. 47-52Dawan, S., Shasany, A.K., Naqvi, A.A., Kumar, S., Khanuja, S.P.S., Menthol tolerant clones of Mentha arvensis: approach for in vitro selection of menthol rich genotypes (2003) Plant Cell Tiss Organ Cult, 75, pp. 87-94Delbarre, A., Muller, P., Imhoff, V., Guern, J., Comparison of mechanisms controlling uptake and accumulation of 2, 4-dichlorophenoxy acetic acid, naphthalene-1-acetic acid, and indole-3-acetic acid in suspension-cultured tobacco cells (1996) Planta, 198, pp. 532-541Dodsworth, S., A diverse and intricate signalling network regulates stem cell fate in the shoot apical meristem (2009) Dev Biol, 336, pp. 1-9Dornelas, M.C., Vieira, M.L.C., Plant regeneration from protoplast cultures of Passiflora edulis var. flavicarpa Deg. and P. cincinnata Mast (1993) Plant Cell Rep, 13, pp. 103-106Dornelas, M.C., Vieira, M.L.C., Tissue culture on species of Passiflora (1994) Plant Cell Tissue Organ Cult, 36, pp. 211-217Dornelas, M.C., Vieira, M.L.C., Appezzato-da-Gloria, B., Histological analysis of organogenesis and somatic embryogenesis induced in immature tissues of Stylosanthes scabra (1992) Ann Bot, 70, pp. 477-482Durkee, L.T., Baird, C.W., Cohen, P.F., Light and electron microscopy of the resin glands of Passiflora foetida (Passifloraceae) (1984) Am J Bot, 71, pp. 596-602Echeverri, F., Arango, V., Quiñones, W., Torres, F., Escobar, G., Rosero, Y., Archbold, R., Passifloricins, polyketides alpha-pyrones from Passiflora foetida (2001) Phytochemistry, 56, pp. 881-885Fernando, J.A., Vieira, M.L., Machado, S.R., Appezzato-da-Glória, B., New insight into the in vitro organogenesis process: the case of Passiflora (2007) Plant Cell Tiss Organ Cult, 91, pp. 37-44Gamborg, O.L., Miller, R.A., Ojima, K., Nutrient requirements of suspension cultures of soybean root cells (1968) Exp Cell Res, 50, pp. 151-158Garcia, R., Pacheco, G., Falcão, E., Borges, G., Mansur, E., Influence of type of explants, plant growth regulators, salt composition of basal medium, and light on callogenesis and regeneration in Passiflora suberosa L.
