Phenotype modification in horticultural crops through hormonal control.

Technological advances in plant molecular genetics, especially in the areas of gene isolation and plant transformation, provide the opportunity to consider strategies which attempt to engineer important crop plants with controlled hormonal responses. Two important agronomic traits which determine crop productivity and which are controlled, at least in part, by plant hormones are postharvest qualities and plant architecture. This paper reviews two approaches for controlling specific physiological and developmental processes in horticultural plants through phytohormone manipulations. One strategy is the manipulation of the biochemistry of synthesis and perception of hormones. Success in controlling ethylene using antisense genes and ACC deaminase is mentioned. This approach is limited to instances where cloned and characterized genes are available. The second method is longer term and uses a genetic approach to define genes which control plant shape, specifically branching and internode elongation. Candidate genes and strategies for isolation are considered.
