Moshe Schein MD, FACS, FCS (SA)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,

Die postoperative Schmerzbehandlung to prevent the confusion of all organic forms.” With these words Charles Darwin opens his chapter on hybridism in The Origin of Species. Darwin, however, goes on to argue that the degree of sterility in crosses is . a specially endowed quality but is highly variable, arising through the processes o

Das Aufgabengebiet des Chirurgeniability for breeding or basic research. 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. During the approximately 60 ye

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
