Clash between energy landscape theory and foldon-dependent protein folding.

green vine of the parasitic dodder plant (Cuscuta) latching onto a host plant. Christian Hettenhausen et al. found that Cuscuta bridges between host plants facilitate the transfer of herbivoryinduced signals from attacked to unattacked host plants. The authors report that the jasmonic acid biosynthesis pathway is required to generate such interplant signaling, which elevates defensive metabolites in host plants and results in enhanced insect resistance in Cuscuta-connected plants.
