Root exudates increased tomato resistance

In this study, the root exudates of potato onion(Allium cepa L. var. agrogatum Don.), greengrocery(Brassica campestris L.), mint(Mentha haplocalyx Briq.) and fennel(Foeniculum vulgare Mill.) were applied to tomato inoculated with root-knot nematodes, and their physiological responses to tomato roots were studied to identify genes and pathways related to tomato resistance, and to explore tomato resistance related regulatory networks.
