Aphid mother and nymphs
Claire Drurey, John Innes Centre
Myzus persicae adult and two nymphs feeding on Arabidopsis. Aphids possess mouthparts composed of stylets that navigate to the plant vascular system, predominantly the phloem, for long-term feeding. The saliva of aphids and other insect herbivores contain virulence proteins (effectors) that modulate plant processes to the benefit of these insects. Scientists at the John Innes Centre on the Norwich Research Park are studying the molecular mechanisms involved in the establishment of interactions of plants with insect pests and insect-vectored pathogens.
