Transgenesis refers to the introduction of heterologous or homologous DNA into a plant genome, resulting in a stable integration and expression (Dixon et al., 2007). The technology offers the opportunity to generate novel genetic variation because it allows the introduction of foreign genes from unrelated species and the down-regulation or up-regulation of endogenous genes. Thus, it is expected to accelerate or complement conventional breeding efforts (see Chapter 19). In the last 15 yr, methodology pertaining to cell culture and genetic transformation has been developed for tall fescue, one of the most intensively studied forage and turf grasses in the area of genetic transformation. Transgenic approaches are being explored to develop novel germplasm in this species (Spangenberg et al., 1998; Wang and Ge, 2006).
