Genetic complementation for aphid resistance in susceptible tomato after transformation with Mi-1.2. Comparison of the mean number of aphids per leaflet in independent experiments between two transgenic lines, 143–11 (A) and 143–31 (B), and the control lines Moneymaker (susceptible) and Motelle (resistant). Five plants per genotype were exposed to each of two different isolates of M. euphorbiae WU-3 (black bar) and WU-4 (cross-hatched bar). Significantly different means within each experiment are indicated by different letters according to Tukey HSD test (P < 0.05).
