Research Overview

Plants and insects interact with one another at various scales of space and time. Herbivory is often stressful for plants, reducing growth, development and consequently, plant productivity. Potato, the third most important crop and a major food source of developing countries, is impacted by a variety of aboveground and belowground herbivores. However, limited tuber damage by Tecia solanivora (Lepidoptera; see figure)commonly known as the Guatemalan tuber moth, increases the mass of undamaged tubers on the same plants (potato variety Pastusa Suprema), a response known as overcompensation. As a postdoctoral researcher in the Jander lab at the Boyce Thompson Institute, I am investigating: (i) the mechanisms of potato overcompensation responses, (ii) whether and how potato plants initiate defense responses against the Guatemalan tuber moth damage, and (iii) the interactions of belowground (Guatemalan tuber moth) and aboveground (Spodoptera spp.) herbivores of potato plants using a combination of molecular biology (RNAseq, real-time PCR, etc.) and analytical chemistry (U-HPLC, GC-MS) tools.
