The impact of insect egg deposition on Pinus sylvestris transcriptomic and phytohormonal responses to larval herbivory

ABSTRACT: Plants activate defensive responses to insect herbivory, but also to the initial step of infestation by many insect species, i.e. the egg deposition. They can even improve their defenses against herbivory by responding to previous insect egg deposition. Molecular analysis of these egg-mediated defenses against herbivory focused so far on angiosperm species. Yet, it is unknown how the transcriptome of a gymnosperm species is responding to insect eggs and subsequent larval feeding. Scots pine (Pinus sylvestris) is known to improve its defenses against herbivorous sawfly larvae when previously having received sawfly eggs. Here, we analyzed the transcriptomic and phytohormonal responses of Scots pine needles to eggs and larvae of the sawfly Diprion pini. Pine showed strong transcriptomic respo
