| Abstract |
Here, we present a protocol for generating and selecting stable transgenic tomato lines through Agrobacterium tumefaciens-mediated transformation of cotyledon and hypocotyl explants. We describe steps for sterilizing and planting tomato seeds, cotyledon and hypocotyl excision and preculture, Agrobacterium tumefaciens preparation and co-cultivation with explants, and recovering explants and bacterial overgrowth restriction. We then detail procedures for selecting green calli; regenerating explant excision and growth in non-selective media; plant hardening, potting, and growing; and T-DNA insertion confirmation by PCR. For complete details on the use and execution of this protocol, please refer to Mountourakis et al.1,2,3.
