Untargeted metabolomic and molecular network approaches to reveal tomato root secondary metabolites

Introduction The tomato plant, Solanum lycopersicum L. (Solanaceae), is one of the most widely consumed vegetables in the world and plays an important role in human diet. Tomato cultivars are hosts for diverse types of pests, implying diverse chemical defence strategies. Glycoalkaloids are the main specialised metabolites produced by tomato leaves and fruits to protect against pests. However, the roots have received little attention, leading to...
