“…Whether or not a signal sequence such as that derived from GNA is needed for bacterial pesticidal proteins to localize to the sieve element may depend on the protein, with relative size being a primary consideration. Indeed, expression of the 71-kDa pesticidal protein Cry11Aa4 ( 22 ) in Hamlin and Valencia ( Citrus sinensis L. Osbeck) without a signal peptide resulted in <44% D. citri nymph mortality after 5 days ( 23 ). This relatively low level of nymph mortality could result from inefficient transport of Cry11Aa4 from the companion cell into the sieve element in the absence of a signal peptide.…”

Pesticidal proteins derived from bacteria such as Bacillus thuringiensis are valuable tools for management of agricultural insect pests and provide a sustainable alternative to the application of chemical insecticides. However, relatively few bacterial pesticidal proteins have been used for suppression of hemipteran or sap-sucking insects such as the Asian citrus psyllid, Diaphorina citri .
