John Carr

John Carr is a Fellow at the University of Cambridge, affiliated with the School of Biological Sciences. His research focuses on Plant-Virus interactions, Defence and signal transduction, and Virus-induced effects on host-insect and host-insect interactions. Carr's work explores how virus infection influences interactions of plants with other organisms and their ability to withstand environmental stresses. His research also involves techniques such as Plant molecular viral and cellular biology, Viral metagenomics, Insect behavioural and performance assays, Liquid and gas chromatography. He is engaged in on-going collaborations with partners in sub-Saharan Africa to develop sustainable methods for controlling the transmission of crop-infecting viruses.

John P Carr is a researcher in Plant Biology, Plant Pathology, Virology, and Defensive Signals. His work focuses on the role of salicylic acid in plant defense mechanisms against viral infections, including its involvement in gene regulation, RNA silencing, and antiviral resistance. Carr investigates how viral proteins, such as the 2b protein of Cucumber mosaic virus, disrupt plant defense pathways and influence virus transmission. His research also explores the interaction between plant signaling molecules and environmental stressors like ultraviolet-B radiation. Carr's studies contribute to understanding the molecular basis of induced resistance and the complex signaling networks that govern plant immunity.
