Podcast: Plant Biochemist is Top Teacher

In this episode of the Three Minute Egghead podcast, meet Judy Callis, professor of molecular and cellular biology, who has just received the UC Davis Prize for Undergraduate Teaching and Scholarly Achievement.

Professor Judy Callis studies the ubiquitin system in plants. She is recipient of the 2018 UC Davis Prize for Undergraduate Teaching and Scholarly Achievement.

Callis teaches biochemistry and her lab studies the ubiquitin system in plants. Once thought to be a way to tag proteins inside cells for “garbage disposal,” ubiquitin turns out to have a ubiquitous role in regulating metabolism.

New Steps in the Meiosis Chromosome Dance

Where would we be without meiosis and recombination? For a start, none of us sexually reproducing organisms would be here, because that’s how sperm and eggs are made. And when meiosis doesn’t work properly, it can lead to infertility, miscarriage, birth defects and developmental disorders.

Neil Hunter’s laboratory at the UC Davis College of Biological Sciences is teasing out the complex details of how meiosis works. In a new paper published online Jan. 6 in the journal Science, Hunter’s group describes new key players in meiosis, proteins called SUMO and ubiquitin and molecular machines called proteasomes. Ubiquitin is already well-known as a small protein that “tags” other proteins to be destroyed by proteasomes (wood chippers for proteins). SUMO is a close relative of ubiquitin.
