Absolutely. My colleagues and I have had some really promising results in creating varieties that grow productively in drought-affected soil. Just recently I've been assisting with a variety of wheat which produces a pheromone that repels aphids and attracts non-destructive insect predators. We've just started trials.

If it's successful then it'll still be a few years before it reaches the commercial market, but it could let farmers in the developing world save huge amounts of money they'd otherwise be spending on dangerous insecticides.
