A zygote is formed after an egg has been fertilized by a sperm. The zygote then develops into an embryo (zygotic embryo). In vitro tissue culture techniques may be used to induce the formation of embryos from somatic tissue (non‐zygotic embryo or somatic embryogenesis) using growth regulators. Somatic embryos arise from a single cell rather than budding from a cell mass as in zygotic embryos. This option is very important in biotechnology since transgenesis in plants may involve the manipulation of single somatic cells. However, without successful regeneration, plant transformation cannot be undertaken. Somatic embryogenesis has been extensively studied in Apiaceae, Fabaceae, and Solanaceae.
