New research article in Journal of Ecology
A research article by Tomonori Tsunoda, Sebastian Krosse, and Nicole M. van Dam entitled “Root and shoot glucosinolate allocation patterns follow optimal defence allocation theory” is now published in Journal of Ecology (http://onlinelibrary.wiley.com/doi/10.1111/1365-2745.12793/full).

Optimal defence theory (ODT) is one of the most prominent theoretical frameworks to explain the allocation of defence compounds within plants. The ODT has been well worked out and experimentally tested for shoot defences, but not for root defences. This paper reported that ODT generally applies to glucosinolate allocation in aboveground and belowground organs and may mainly serve to maintain the integrity of the main plant structure. Moreover, it suggests that aboveground and belowground insect herbivores independently exert similar selection pressures on defence allocation patterns in root and shoots.
