Genetic Transformation of Somatic Embryos
Abstract
Although DNA can be introduced into virtually any plant cell, several biological constraints still exist for the regeneration of transformed plants. These biological constraints are linked to the ability of an individual cell to respond to both the introduced DNA and to a regeneration stimulus. For transformation success, the plant cell must have certain attributes which include (1) the competence to express the introduced DNA; (2) the competence for stable integration of introduced DNA; and (3) the competence to regenerate into a whole plant. The competence to express introduced DNA at a high level as well as ability to differentiate plants from single cells has made somatic embryogenesis a useful tool in plant transformation. In fact, somatic embryogenesis has been instrumental in the regeneration of transformed plants from recalcitrant species in such divergent plant groups as monocots and gymnosperms. Examples of somatic embryogenesis used in the regeneration of transformed plants are listed in Table 1.
