Periodic Reporting for period 1 - DARES (Associational resistance and neighbor recognition of in common dandelion roots)
Reporting period: 2016-03-01 to 2018-02-28
Basically, I have fully reached objective (1) and (2) and made significant progress towards three over last two years from March 1, 2016 to September 30, 2017. I found that neighboring plant significantly affected T. officinale root defenses, which in turn influenced the performance of M. melolontha larvae feeding on T. officinale. This associational effect was triggered by both root volatile and exudates released by neighboring plant. Terpenes were identified as major active singles. So far, one paper entitled “Neighbourhood effects determine plant-herbivore interactions below-ground” has been published in Journal of Ecology in 2017 and also presented as a poster in 16th Symposium on Insect-Plant Relationships in France, one manuscript is being under review in Functional Ecology, and some raw data is being processed.
