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,

The wide use of model plant mutants, in studies of molecular organization of genomes or of metabolic pathways, has stimulated interest to utilize these techniques in crop improvement by conventional or molecular genetic methods.

Because of the importance of rice production, extensive research efforts and progress have been made during the last 30 years to improve yields. Most of this research ha

Marco Kesting,Rainer Lutz,Manuel Weberlts 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
