Relationship between Acylsugars and Leaf Trichomes: Mediators of Pest Resistance in Tomato
Tomato plants are highly susceptible to pests. Among the control methods, genetic improvement with introgression of resistance genes from wild accessions into commercial tomato lines is the best alternative for an integrated pest management (IPM).

| description | Tomato plants are highly susceptible to pests. Among the control methods, genetic improvement with introgression of resistance genes from wild accessions into commercial tomato lines is the best alternative for an integrated pest management (IPM). Thus, the objective of this study was to select tomato genotypes in advanced populations (F<sub>2</sub>BC<sub>3</sub>), with higher levels of acylsugar content, greater recurrent parent genome recovery, and resistance to <i>Tetranychus urticae</i> and <i>Bemisia tabaci</i> inherited from <i>Solanum pennellii</i>. For pest resistance, bioassays were assessed: nine high-acylsugar genotypes, four low-acylsugar genotypes, and the parents, <i>Solanum lycopersicum</i> or ‘Redenção’, and <i>Solanum pennellii</i> LA-716. Glandular and non-glandular trichomes were quantified. A negative correlation was measured between acylsugar content in the leaflets and pest behavior. Pest resistance was found in the selected F<sub>2</sub>BC<sub>3</sub> genotypes with high-acylsugar content, indicating that this allelochemical was efficient in controlling the arthropod pests. |
