New preprint out! Zhoubo Hu et al "A redox-regulated RCC1-like protein controls catalase activity in Arabidopsis". We identify CAIR1, a UVR8-interacting protein, as a redox-responsive regulator of catalase localization and activity, maintaining cellular ROS balance. 🌱

A+ advice
Advice I now give to grad students and postdocs in the sciences: Don’t just try to meet and impress senior scientists. They’ll retire soon. Get to know your fellow students - make friends where possible, be colleagues at least. These are the people you’ll be sharing the field with for decades.
