Hubbard et al 2019 find that root microbes drive a substantial amount of plant defense in Boechera stricta, and that plant and root-microbe pathways to defense are different. I opine here on what separate pathways mean for evolution of plant defense, and what alternate knock-on effects of microbe- and plant- driven defense on insects could mean for tri-trophic interactions.
