Genetic Manipulation of Forest Trees: Implications for Physiological Processes

  • Don J. Durzan
Part of the NATO ASI Series book series (NSSA, volume 186)


With the recent advances in biotechnology of woody perennials (Durzan, 1988ab, 1989, 1990; Hällgren, 1988; Haissig et al, 1987; Torrey, 1988), considerable interest has developed in gene expression, particularly as transgenic trees are being regenerated. Progress in physiological aspects of biotechnology is evaluated against current schemes for domestication and tree improvement (Haissig et al., 1987; Timmis et al., 1986). An attempt is made to illustrate how elite or foreign genes may be expressed in quantitative terms against different genetic backgrounds. Notions from metabolic control theory involving preconditioning factors become useful, especially when examining the rejuvenation of cells for clonal propagation and gene insertion. The general area involving gene manifestation, penetrance and expressivity has been termed molecular phenogenetics (Durzan, 1990).
