Hybrid potatoes bearing glandular trichomes from the wile Bolivian potato, Solanum berthaultii, are well defended against infestation and colonization by aphids, leafhoppers, and flea beetles (12). Populations of these damaging pests on elite hybrids are often reduced more than 85%, compared to those on susceptible commercial cultivars (13). Furthermore, many hybrids severely disrupt aphid feeding behavior and host acceptance in a manner comparable to that of their wild parent, an important attribute considering the worldwide importance of aphids as vectors of potato virus pathogens.

Isolation of a cDNA encoding an SCPL protein responsible for the synthesis of glucose polyesters has been reported [120], These compounds are produced in trichomes of Lycopers icon pen-nellii and Solanum berthaultii as a defense against insect attack. An SCPL enzyme responsible for the formation of UV-protecting sinapoyl malate in leaves of the Brassicaceae has also been described [121].

The wild tomato, Lycopersicon pennellii, and the wild potato, Solanum berthaultiif are two species which exhibit insect resistance conferred by glandular trichomes. S, berthaultii and L. pennellii have been the focus of efforts at Cornell University to transfer trichome-based insect resistance traits. This chapter reviews our knowledge of the biochemistry of glandular trichome-based insect resistance in these species.
