Current research interests
- Functional analysis of effectors of plant parasitic nematodes.
- Genomics of the potato cyst nematode Globodera pallida.
- Horizontal gene transfer in plant parasitic nematodes.
John has a joint appointment at the University of St Andrews
John is part of the Dundee Effector Consortium.
- Work in our group is focused on identification and characterisation of secreted effector proteins of plant parasitic nematodes, with a particular focus on effectors that suppress host defences.
- Our work uses genomics tools to identify and characterise effectors. We have been involved in projects sequencing genomes and transcriptomes of a range of plant-parasitic nematodes.
- One unexpected finding that has emerged from this work is that genes important in the parasitic process seem to have been acquired by horizontal gene transfer, from bacteria or fungi, in all groups of plant parasitic nematodes studied to date.
- Current work is aimed at functional characterisation of proteins we suspect are important in generating a susceptible response or suppressing host defences in plants.
