Host-Plant Resistance in Tomato

© 2018 Elsevier Inc. All rights reserved. Tomato plants are attacked by a diverse assemblage of pests and have served as an important model for the study of plant resistance. A large number of biochemical and morphological traits have been implicated in resistance to tomato pests, including trichomes and trichome-associated compounds, resistance-related proteins, and a diverse assortment of secondary metabolites. Wild tomatoes often possess higher levels of these traits and thus represent important genetic resources for resistance breeding. Various aspects of induced resistance, such as the hormonal pathways and metabolic changes associated with induced resistance and the genes governing vertical resistance, have been well studied in tomato. Host-plant resistance currently plays an important role in disease but not arthropod management programs in tomato. The voluminous literature on resistance in tomato, coupled with the availability of comics tools, makes future successes in developing pest-resistant tomato varieties likely.
