Dominant Gene That Delays Flowering
WARF: P01338US

Inventors: Richard Amasino, Scott Michaels, Si-Bum Sung, Fritz Schomburg, Edward Himelblau

The Wisconsin Alumni Research Foundation (WARF) is seeking commercial partners interested in developing a gene from Arabidopsis that affects flowering in plants and can be used to improve production of vegetables and forage crops.
The transition between vegetative growth and flowering (reproduction) represents a major developmental shift in the plant life cycle.
The Invention
UW-Madison researchers have developed a powerful tool for delaying flowering in plants, allowing plant breeders to control the growth and development of agriculturally and horticulturally important species. They isolated a gene from Arabidopsis thaliana that when expressed at higher than normal levels causes a substantial delay in flowering. Overexpression of this gene also appears to render the plant insensitive to factors that normally induce flowering, such as treatment with the hormone gibberellin or exposure to flower-promoting light conditions. Tests are underway to introduce this gene into other species.
  • Production of vegetables and forage crops
Key Benefits
  • Hybrid seed production could be made easier by controlling flowering in one or both parents.
  • Delay of flowering may be used to increase the vegetative growth and yield of vegetables such as lettuce, spinach, potatoes and beets, and of forage crops, such as alfalfa and clover.
  • Because the gene acts dominantly, it should create the desired phenotype in a broad range of plant species without further modification.
