Fig. 4From: Variation in both host defense and prior herbivory can alter plant-vector-virus interactionsPlant volatile emissions as a function of genotype and prior MED infestation. A spr2 plants. B WT plants. C 35S plants. This protocol used 81 (three treatments × three genotypes × nine replicates) plants. Square grid bars: non-infested control plants; open bars: plants infested with virus-free MED; striped bars: plants infested with viruliferous MED. Within each group, bars with different letters are significantly different (P < 0.05)Back to article page
