Targeting Genes for Genetic Manipulation in Crop Species,llelic variation within the species, or by the introduction of novel alleles or ‘new’ genes from outside of the species. In essence, the technologies to achieve this are already developed or are, presently, in an advanced state of development. First, the technologies for interplant, within species,

Genetic Transformation of Maize Cells by Particle Bombardment and the Influence of Methylation on Flts from these studies of the structure of plant gene regulatory regions have been reviewed recently (Schell, 1987; Willmitser, 1988). Additionally, the development of techniques for transferring genes into crop plants allows new agronomic traits to be introduced (Goodman et al., 1987). Recently, re
