Rust spore harvesting went well today! Thanks to our summer student Michael :)

This work will also allow the exploration of resistance genes diversity and their gene flow between wild populations and to assess the impact of proximity with cultivated beets. Excited to discover genetic diversity for wild sea beet resistance to pathogens!

My association analysis is based on 3 large-scale rust inoculation experiments with 2 English and 1 Danish rust isolates, on ~600 wild European sea beets, in controlled conditions. I am then selecting the most and least resistant plants to include them in the association study.

There is also the adaptation of wild hosts to consider (@HeleneYvanne) in addition to lots of other areas such as modelling invasions. I'd be really keen to chat to people thinking along these lines or just interested in next steps. Thanks.

Until recently all agricultural pathogens lived on a wild host. We developed the beet system to explore pathogen genetic reservoirs to explain how crop pathogens quickly adapt to new resistance. Here, we identify a signal of adaptation in a rust pathogen. Photo by @GreyMj 1/
