The paper shows that cytosolic Ca2+ acts as a universal signal for rapid root growth regulation in response to various stimuli.

The paper uses optogenetics to show that Ca2+ signals regulate early auxin signaling in Arabidopsis roots, affecting growth and transcriptional responses.

This study develops and applies expansion microscopy to Arabidopsis root tissues, achieving improved resolution and visualizing subcellular structures.

The paper shows that calcium-triggered apoplastic ROS bursts balance gravity and mechanical signals to regulate root bending during soil navigation.
