Tecia solanivora infestation increases tuber starch accumulation in Pastusa Suprema potatoes
Journal of Integrative Plant Biology, 2018 AbstractIn response to infestation with larvae of the Guatemalan tuber moth (Tecia solanivora), some Solanum tuberosum (potato) varieties exhibit an overcompensation response, whereby the total dry mass of uninfested tubers is increased. Here, we describe early responses, within the first few days, of T.
