Fellow of Corpus and Professor of Plant Virology at Cambridge University’s Department of Plant Sciences, John Carr, has been recognised with an Honorary Membership by the British Society of Plant Pathology.

The Society said in its announcement, “His career has significantly advanced our understanding of plant interactions and defensive signalling in plants.

After completing a Biochemistry degree at the University of Liverpool, John’s early research focused on pathogenesis-related proteins during a formative period in plant defence research. This work built upon pioneering discoveries demonstrating that salicylic acid could induce resistance responses in plants, research that helped shape today’s understanding of plant immune signalling.

Subsequent postdoctoral research in the laboratories of Dan Klessig and Milt Zaitlin further explored gene expression in response to virus infection. It contributed to early insights into salicylic acid as a natural endogenous defence signal. His later work at the University of Cambridge investigated defensive signal transduction pathways, virus–plant interactions, and the complex relationships between plants, viruses and insect vectors such as aphids, alongside beneficial insects including pollinators.”

John has also been a gifted teacher and supervisor at Corpus. Recent PhD graduate and now postdoc Dr Satish Viswanathan says, “I am very glad to hear that John has been made an Honorary Member of BSPP. He truly deserves the honour. Over my five years as a PhD student and a postdoc, he has been an excellent supervisor, guiding me well through all situations. The best thing about him is that he genuinely cares about your well-being and wants you to do well on all fronts. I am very lucky to have him as my mentor. And of course, anyone who has met him would attest to his excellent sense of humour.”

 Throughout John’s career, collaboration and mentorship have played a central role, alongside long-standing contributions to the BSPP community. In accepting the Honorary Membership, He expressed gratitude for the Society’s continued support and for fostering a strong and welcoming network of plant pathologists, saying, “To echo my fellow Liverpool FC supporter Gary Foster (2004), who is one of many very hard acts to follow in the list of previous honourees, I am truly humbled and honoured that the British Society for Plant Pathology has awarded me an Honorary Membership.”

Many congratulations to John for this recognition of his work.
