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
