VecTranTM technology is the next generation of stacked-trait insertion.
YieldGard VT® 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® Rootworm/RR2 and YieldGard VT® Triple.
YieldGard VT® hybrids contain a better promoter.
A huge benefit of YieldGard VT® 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® hybrids, YieldGard VT® 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®
YieldGard VT products have a more-effective promoter, which delivers a more-consistent level of insecticidal protein expression.
