Rate My Professor Paul Jarvis

Jarvis's research centers on the biogenesis and operation of chloroplasts and other plastids in plants, with a particular emphasis on the import of nucleus-encoded proteins and regulation by the ubiquitin-proteasome system. His laboratory employs molecular, genetic, cellular, and biochemical approaches using the model plant Arabidopsis thaliana as well as crop species such as tomato, wheat, and rice. Key discoveries from his group include the direct regulation of chloroplasts by the ubiquitin-proteasome system and the definition of chloroplast-associated protein degradation (CHLORAD), mediated by the outer envelope ubiquitin E3 ligase SP1. These findings influence plastid proteome control, developmental fate, abiotic stress responses, and have applications in crop improvement for yield, fruit ripening, and stress tolerance. Notable publications include "Biogenesis and homeostasis of chloroplasts and other plastids" (Nature Reviews Molecular Cell Biology, 2013, with E. López-Juez), "Chloroplast biogenesis is regulated by direct action of the ubiquitin-proteasome system" (Science, 2012), "Ubiquitin-dependent chloroplast-associated protein degradation in plants" (Science, 2019), and "The chloroplast-associated protein degradation pathway controls chromoplast development and fruit ripening in tomato" (Nature Plants, 2021). He also edited the two-volume "Chloroplast Research in Arabidopsis: Methods and Protocols" (Methods in Molecular Biology, 2011).
