PCT Patent Application Filed

In many countries cotton (Gossypium spp.) is one of the most important fiber producing plants.  The main concerns in growing cotton are the inverse relationship between cotton fiber qualities and high yields. The disclosed technology proposes a way to solve the problem of growing immature and short cotton fibers caused by drought stress. There currently are no known solutions to this problem, other than traditional breeding with the modification of particular genes involved in cotton maturation. The technology shows that RAV genes are indeed important for plant hormone abscisic acid and environmental signaling roles in fiber quality.


Market Applications:

  • Agricultural biotechnology
  • GMO crops


Features, Benefits, & Advantages:

RAV overexpression in cotton increases fiber length and delays flowering via up-regulation of genes involved in fiber initiation and fiber elongation, as well as down-regulation of genes involved in flowering initiation.

  • Drought tolerance
  • No flowering of immature plants
  • No short cotton fibers


Development Stage:

This technology has been tested in the field.


Intellectual Property:

A US provisional application was filed 12/09/2014 and a PCT application was filed 12/09/15.
