Shakesby AJ, Wallace IS, Isaacs HV, Pritchard J, Roberts DM and Douglas AE, 2009. A water-specific aquaporin involved in aphid osmoregulation. Insect Biochemistry and Molecular Biology 39, 1-10.

Ally Shakesby and Angela collaborated with Dr Dan Roberts and Ian Wallace (Knoxville, Tennessee), Dr Jeremy Pritchard (Birmingham, UK) and Dr Harv Isaacs (York, UK) to study the gut aquaporin in the pea aphid.  We established that the aquaporin gene ApAqp1 is the ortholog of the gene drip (CG9023) expressed in the Malpighian tubules of Drosophila. The aphid gene is expressed in the stomach and distal intestine; and our RNAi studies suggest a role of the aphid gut aquaporin in water cycling.
