Model of C. campestris resistance response in tomato cultivars. Red-labeled pathway: identified cytosolic CuRLR1, which may receive large signaling molecules from C. campestris or play a role in signal transduction upon Cuscuta perception. This triggers downstream signal transduction and induces a lignin-based resistance response. This resistant response may be an ETI. Pink- and yellow-labeled pathway: SlMYB55 and LIF1 function as positive regulators in the lignin biosynthesis pathway. Yellow- and green-labeled pathway: SlWRKY16- and LIF1-mediated lignin-based resistant responses and with a potential connection to CuRe1. Blue-labeled pathway: previously identified CuRe1-mediated PAMP/MAMP-triggered immunity pathway. ROS, reactive oxygen species.
