Abstract
Organogenesis and somatic embryogenesis have been critical to the development of transgenic plants in most major crop plants, and historically empirical studies have been used to develop the regeneration systems used in crop plants. With a greater understanding of the genetic and developmental pathways leading to organogenesis and somatic embryogenesis better methods of producing transgenic plants might be developed. Ultimately non-tissue culture based methods of plant transformation should result from these efforts to deliver transgenic plants more rapidly and economically.
