1. Optimize conditions that give high fecundity of soybean aphids on soybean hairy roots
2. Identify and evaluate aphid resistance in hairy roots, using genes from soybean and other plants, and through the silencing of native aphid and bacterial endosymbiont genes
3. Identify and characterize resistance and biotype adaptation mechanisms using molecular, bioinformatic and metabolomic approaches
4. Introduce resistance genes into whole plants
