Dwarfism Genes and Dwarf Plants


Richard Amasino, Fritz Schomburg, Scott Michaels, Colleen Marion

The Wisconsin Alumni Research Foundation (WARF) is seeking commercial partners interested in developing a gene that may be used to alter the height of a plant or the size of a specific plant organ.
OVERVIEWCompact or dwarf crop plants have many advantages in agriculture, including denser growth, increased resistance to storm damage and reduced loss during harvesting. In horticulture, dwarf varieties are often more desirable as bedding plants. Levels of gibberellins (GAs), a group of tetracyclic, diterpene carboxylic acids involved in a variety of developmental processes, are commonly modified to alter plant size.
THE INVENTIONUW-Madison researchers have identified the function, cDNA sequences and expressed amino acid sequences of a gene that affects gibberellic acid levels in plants. This dominant gene may be used to alter the height of a plant or to alter the size of a specific plant organ. When over-expressed in a plant, this gene reduced the level of bioactive GA, resulting in a plant that produced the same amount of seed as a wild-type plant, but was more compact.
  • Creation of dwarf transgenic plants, which are more resistant to storm damage and easier to harvest
  • Creation of transgenic plants with a specific dwarf organ
  • Gene can be easily introduced into plants due to its dominant nature.
  • Different promoters may be used to fine-tune gene expression to produce specific alterations to plant structure.
  • Useful in a variety of plants, including both monocots and dicots
