GM crops can help reduce greenhouse gas emissions in three main ways: 1) They allow for reduced use of pesticides and fertilizers, which saves on fuel used in farming equipment and leads to less nitrous oxide, a potent greenhouse gas, escaping into the atmosphere from fertilized fields. 2) Crops with improved nitrogen use efficiency traits require less nitrogen fertilizer, reducing associated greenhouse gas emissions from fertilizer production and runoff. 3) Drought tolerant crops in development could help farmers conserve water while maintaining yields, providing an adaptation strategy for climate change.

Editor's Notes
- As mentioned earlier, another yield enhancement research project includes demonstrating technical proof of concept that crop performance in response to nitrogen inputs can be enhanced through biotechnology. As you know, nitrogen is one of the most important nutrients for crop growth, second only to water. Nitrogen is one of the most important and widely used farm inputs, so any product that aids in the efficiency of nitrogen use will have some obvious performance benefits at the farm level. We target to get 10% yield increase over elite varieties at time of launch or equivalent yield with 50% less nitrogen fertilizer
- In Canada, hybrids are also used for weed control. They grow very vigorously early and create canopy closure that makes it difficult for weeds to germinate. These photos show an InVigor hybrid and an open pollinated canola crop after the same herbicide treatment.
- if you grew up in the heartland (ie, Illinois) and watched what happened in years of little rain, you also can’t help be excited about the progress our R&D team is making in drought tolerance. Drought tolerance is one of several approaches in our pipeline to enhancing yield – other approaches look at cold tolerance, salt tolerance and nitrogen uptake. The value in this trait can come in one of three ways – yield insurance, yield enhancement and cost savings in irrigated land. The demand will be there – not only is the need for water inherently understood, but the value of water is soaring, and the resource is one we’ll need to protect. Today, agriculture is, without question, the largest consumer of water. Did you ever think it would be exciting to watch corn grow? I sure do….the video you’re seeing is a time lapsed video of drought tolerance in the field – only last year I would have been showing you pictures from the lab. As you watch, look for how the leaves on the corn on the left curl from lack of water. --------------------------------------------------------- Little picture of movie, click movie, then click to next slide As excited as I am about Omega-3, if you grew up in the heartland and watched what happened in years of little rain, you also can’t help be excited about this trait for drought tolerance.

As you watch, look for how the leaves on the corn on the left curl from lack of water. From a research perspective, there are a few key milestones: One, you’re looking at the first in a multi-generational pipeline of drought tolerant products. Commercially, this will be a major and protracted business opportunity with continued introduction of next generation traits. Two, this year, we’ve advanced two lead products, and we have 30 additional hits in Phase 1 in our gene screening program. Three, next year, we will be stacking the drought tolerant gene with our weed and insect control products – again, the farmer will demand a stacked product from the outset, so you have to prepare for that early in your research. And four, we’re extending this initial research in corn into our other core crops, particularly canola, which is being enhanced by our recently announced canola seed acquisition.
