Advances in Tissue Culture and Transformation Studies in Non-model Species: Passiflora spp. (Passifloraceae)

Methods Mol Biol. 2024:2827:207-222. doi: 10.1007/978-1-0716-3954-2_15.

Abstract

In this chapter, we report advances in tissue culture applied to Passiflora. We present reproducible protocols for somatic embryogenesis, endosperm-derived triploid production, and genetic transformation for such species knowledge generated by our research team and collaborators in the last 20 years. Our research group has pioneered the work on passion fruit somatic embryogenesis, and we directed efforts to characterize several aspects of this morphogenic pathway. Furthermore, we expanded the possibilities of understanding the molecular mechanism related to developmental phase transitions of Passiflora edulis Sims. and P. cincinnata Mast., and a transformation protocol is presented for the overexpression of microRNA156.

Keywords: Developmental phase transitions; Endosperm culture; Genetic transformation; In vitro morphogenesis; MicroRNAs; Passiflora; Somatic embryogenesis; Triploids.
