1. Using activation tagging to identify genes conferring resistance to feeding insects
Our lab uses genetic mutant populations of poplar to screen for individual trees that display altered resistance to insect herbivores. These genetic screens facilitate an unbiased approach to identify novel plant defense mechanisms and regulatory networks. This strategy is extremely powerful when combined with the emerging datasets describing the insect-induced poplar transcriptome.
