Plant-microbe mutualisms can improve plant defense, but the impact of root
endophytes on below-ground herbivore interactions remains unknown. We
investigated the effects of the root endophyte Piriformospora indica on
interactions between rice (Oryza sativa) plants and its root herbivore rice water
weevil (RWW; Lissorhoptrus oryzophilus), and how plant jasmonic acid (JA) and GA
regulate this tripartite interaction. Glasshouse experiments with wild-type rice
and coi1-18 and Eui1-OX mutants combined with nutrient, jasmonate and gene
expression analyses were used to test: whether RWW adult herbivory above ground
influences subsequent damage caused by larval herbivory below ground; whether
P. indica protects plants against RWW; and whether GA and JA signaling mediate
these interactions. The endophyte induced plant tolerance to root herbivory. RWW
adults and larvae acted synergistically via JA signaling to reduce root growth,
while endophyte-elicited GA biosynthesis suppressed the herbivore-induced JA in
roots and recovered plant growth. Our study shows for the first time the impact
of a root endophyte on plant defense against below-ground herbivores, adds to
growing evidence that induced tolerance may be an important root defense, and
implicates GA as a signal component of inducible plant tolerance against biotic
stress.
