Categories

Agriculture, transgenic plants, amino acid sequences, pathogen resistance, Botrytis cinerea, powdery mildew Sphaerotheca fuliginea

Development Stage

Resistance to Botrytis cinerea demonstrated  in a commercial crop

Patent Status

Patent application filed

Market Size

Biopesticides: 1.4% ($380 million) of $28 billion global market

Highlights

  • Demonstrates genetic constructs and amino acid sequences conferring resistance to plant pathogens, especially resistance to Botrytis cinerea, Sphaerotheca fuliginea and the viruses TMV, PVY, YLCV
  • No undesired effects when consumed: Resistance achieved by transfecting plants with sequences naturally occurring in cucumber plants or homologous genes from other plants
  • Facilitates selection of pathogen-resistant plants
  • Research demonstrates that infection on the leaves of plants with increased expression of the hetrologous sequence both in-vitro and in the growth chamber was two- to three-fold higher than in control plants
  • Resistance demonstrated in tomato plants

Our Innovation

  • Transfecting plants with a naturally occurring hetrologous sequence confers resistance to many common plant pathogens and in particular Botrytis cinerea
  • With this innovation, plants will have:
  • A smaller number of infected loci
  • A smaller area of infected loci
  • A shorter infection period
  • Longer delay before infection

 

The Opportunity

  • Plants with increased resistance to common pathogens

Development Milestones

  • To identify target commercial varieties and to generate transgenic plants with the constructs or to isolate homologous sequences and to use them as markers in breeding programs
  • To test rose and banana plants for the resistance to pathogens

Additional Information
