DESCRIPTION: The current invention involves the use of certain
genes that control floral organ expression. By causing the over expression of
these genes using transgenic technology, the process of floral petal abscission
is blocked down stream of the regulatory point involving ethylene. This abscission
is much sought after in the ornamental flower industry, as well as oil seed
production and in may vegetable crops because chemical retardants and genetic
manipulation of the ethylene pathway have proven only partially successful in
preventing flower wilt and loss and prolonging flowering duration and shelf
life.
ADVANTAGES:
- Trait is genetically engineered into the plant
- No need for external chemical application
- Widely applicable to many species
- Other phenotypic aspects not altered
