Dependency of resistance traits (defenses and tolerance) and primary metabolism. Primary metabolism is fueled by energy and resources, which the plant gains from its environment. Primary metabolism involves growth, storage, and reproduction. Tolerance depends on primary metabolites and energy, both of which are taken from pools for reproduction, storage, and/or growth, and later reinvested in reproduction. Defenses from secondary metabolism are based on energy and resources from primary metabolism, which can be partially resupplied to primary metabolism. Parts of primary metabolism can function as direct defense.

Figure 2.
Resistance signaling is elicited differently from simple wounding when herbivore-specific elicitors (FACs) are introduced into wounds during caterpillar feeding. Signaling depends on primary metabolites. Herbivory induces a large reorganization of primary metabolism, including altered photosynthesis and altered sink/source relations. These changes are coordinated by a signaling network that is only partially understood. The expression of defense and tolerance traits requires changes both in primary and secondary metabolism.
