YieldGard VT^TM Technology

VecTran^TM technology is the next generation of stacked-trait insertion.

YieldGard VT^TM technology combines traits into a single DNA-insertion process, which is more efficient and less time-consuming in developing hotter products containing stacked traits. This process is called VecTran technology, which stands for “Vectorstack Transformation”.

With VecTran technology, two or more genes are inserted together, side-by-side, into the plant chromosome. It is a more-natural insertion process and increases the number of potential products containing the stacked-traits on sites of the chromosomes.

And because it bypasses the traditional breeding process, growers can get elite germplasm with better, higheryielding traits 6 to 12 months faster. The initial products will be YieldGard VT^TM Rootworm/RR2 and YieldGard VT^TM Triple.

YieldGard VT^TM hybrids contain a better promoter.

A huge benefit of YieldGard VT^TM products is that you get stacked-trait hybrids with a highly active and more consistent promoter of the rootworm gene. The promoter is a biotech switch that turns on the gene to produce the insect-control protein and more effectively distribute it throughout the root system.

What makes a VT hybrid better at insect protection?

When comparing the roots of first-generation YieldGard hybrids to new YieldGard VT^TM hybrids, YieldGard VT^TM roots express a more-consistent distribution of insecticidal protein. The accompanying photo shows that the firstgeneration YieldGard roots sufficiently express insecticidal protein. The second photo shows that new YieldGard VT^TM

YieldGard VT products have a more-effective promoter, which delivers a more-consistent level of insecticidal protein expression.
