We work on genes and signals in plant defence and development, that allow plants to function in an integrated manner. Functional genomics enables us to address these questions directly. In particular, we can exploit proteomics and transcriptomics in combination with the widespread availability of mutants and transgenics. For plant defence against aphids, we are particularly interested in genomics and species-wide diversity of both pest virulence and host resistance (Kanvil et al. 2014a), in genetics of aphid virulence (Kanvil et al. 2014b) and in phloem defences against aphids (Kanvil et al. 2017). We have also invested time in developing tools for studying systemic signalling, especially micro-grafting and sap sampling in Arabidopsis. We have published on both phloem (Corbesier et al. 2007; Truman et al. 2007; Zhang et al. 2010; Lopez-Cobollo et al. 2016) and xylem (Foo et al. 2007) systems.
