Fig. 7. The figure demonstrates accumulation of aphid population after 40 d on a transgenic plant ACA #8 expressing Allium cepa agglutinin (ACA) lectin peptide versus an untransformed plant. On the 40th day, the flowering twig shows (A) only a few aphids are present in the transgenic ACA #8; (B) the twig is fully infested with aphids on the untransformed control plant parts.
