Intraspecific Variation in Plant Defense Alters Effects of Root Herbivores on Leaf Chemistry and Aboveground Herbivore Damage [PDF]
, 2008 Root herbivores can indirectly affect aboveground herbivores by altering the food quality of the plant. However, it is largely unknown whether plant genotypes differ in their response to root herbivores, leading to variable defensive phenotypes.

Microorganisms and nematodes increase levels of secondary metabolites in roots and root exudates of Plantago lanceolata [PDF]
, 2010 Plant secondary metabolites play an important role in constitutive and inducible direct defense of plants against their natural enemies. While induction of defense by aboveground pathogens and herbivores is well-studied, induction by belowground ...

Host Plant Effects on Immune Response Across Development of a Specialist Caterpillar
Frontiers in Ecology and Evolution, 2019 Some herbivorous insects sequester chemicals from their host plants, which can serve as a defense against predators. However, sequestration can also be costly, impacting immunological responses important for other types of natural enemies, such as ...
