To reduce fungicide usage required for potato production worldwide.
We will use “next generation”, high throughput cDNA sequencing to understand disease response pathways in the potato foliage and tuber. Our data will be integrated into large-scale deployment efforts for RB, a gene conferring foliar late blight resistance to potato.
Worldwide, potato is the fourth most important human food crop. Potato has gained major significance in developing nations in recent years. Potato production is heavily chemical dependent. Late blight disease affects both foliage and tubers, causes multibillion dollar losses annually, and requires the use of millions of tons of fungicides for control. The foliar late blight resistance gene RB can reduce fungicide usage and is expected to be deployed in India as soon as 2012. Our project will provide the basic science knowledge needed to effectively deploy RB. Specifically, our research tests the impact RB has on tuber late blight disease and explores the effects reduced (but not eliminated) sporulation on potato foliage will have on stored tubers. Framework recommendations for reduced or eliminated fungicide usage for potato production within the context of RB deployment will result.
