Gigantus1, A Newly Identified Gene Target for Improved Plant Growth and Yield in Agricultural Applications

Gts1- knockout plants (Gts-1) displayed faster germination and increased growth compared to wild-type (WT) plants.


Invention Summary:

Rutgers scientists discovered a new gene Gigantus1 (Gts1) in Arabidopsis thaliana, which significantly influences seed germination, growth and biomass accumulation in plants.
​​​​​​​
The protein product GIGANTUS1 (GTS1) belongs to the WD40 protein superfamily, whose members are key regulators of plant development. Under the same growth conditions, Gts1 -knockout plants germinated faster and had significantly increased growth compared to WT plants (Fig. A on top). They also flowered 5 days earlier and accumulated higher cell biomass than WT, as shown by a bigger overall rosette leaf area (Fig. B on top). In addition, they yielded more than 5-fold the amount of seeds at harvest time compared to WT. The Arabidopsis Gts1 gene is very similar to that of rice and maize. A method to reduce Gts1 expression in maize was also successfully developed.

 

Market Applications:

Gts1 targeting in plants can be used to improve

  • Crop growth and yield
  • Plant-based biofuel production
  • Landscape restoration


Advantages:

  • Efficient growth and yield promotion
  • Easy modification of Gts1 expression
  • Economical application in rice, maize and other important plants
  • Combination with other beneficial transgenic traits in plants
