Transcriptomic and cell wall mechanisms mediating root hair changes in spaceflight

Spaceflight alters Arabidopsis root hair morphology through coordinated changes in peroxidase gene expression and cell wall remodeling, as revealed by transcriptomic and proteomic responses. These modifications may underlie observed differences in root development under microgravity.
