Congratulations to Ivan Kulich from IPMB, Biology Centre CAS for his new paper in Science looking at calcium, ROS and root growth @MOLIPEC www.science.org/doi/10.1126/...

New Editorial: "Photorespiration benefits" rdcu.be/e9W3h Photorespiration was long considered a futile cycle leading to a net carbon loss. However, evidence is accumulating that substantial metabolic benefits exist. #PlantScience

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. 🌱 www.biorxiv.org/content/10.6...
