Description
Online Poster PresentationAbstract:
Potato production is significantly reduced by biotic and abiotic threats such as insect attacks, water scarcity, and elevated or low temperatures; thus, research to identify and characterize new sources of resistance and tolerance is imperative. Plant stress responses involve independent mechanisms; hence, identifying common resistance/tolerance traits constitutes a challenge. In this context, trichomes play a pivotal role in plant-insect and plant-environment interactions. These structural traits can act as a physical and chemical barrier affecting insect feeding, oviposition, mobility, reproduction and survival. In addition, their spatial patterns have been associated with tolerance drought, heat, cold and UV overexposure. However, the relation between trichome biogenesis genes, their different morphotypes and plant resistance/ tolerance to multiple biotic and abiotic stresses, as far as we know, have not been investigated in potato species. Therefore, this project aims to characterize the trichomes morphotypes of wild potato accessions, their link with plant responses to insect (whitefly, aphids, and Colorado potato beetle) attack, drought, heat and chilling stresses, and its used as potential breeding targets for combinatorial resistance/tolerance.
