  • To enable the generation of transgenic tomato lines for diverse applications, including pharmaceuticals and agriculture.
  • To provide methods for molecular characterization and fruit processing of transgenic lines.

Main Methods:

  • Agrobacterium-mediated transformation utilizing tomato cotyledons as explants.
  • Generation of transgenic lines expressing genes of interest and selectable markers.
  • Molecular characterization techniques for verifying transgene integration and expression.
  • Protocols for batch processing of tomato fruit from transgenic lines.

Main Results:

  • Successful generation of transgenic tomato lines from multiple cultivars.
  • Demonstration of effective gene expression and selectable marker activity in transgenic plants.
  • Established protocols for molecular confirmation and fruit processing.

Conclusions:

  • Agrobacterium-mediated transformation of tomato cotyledons is an efficient method for generating transgenic lines.
  • This protocol supports the development of genetically modified tomatoes for pharmaceutical and agricultural advancements.
  • The described methods facilitate comprehensive analysis and utilization of transgenic tomato resources.
