Arabidopsis PIEZO Regulates Root Growth in Response to Magnetic Field and Blue Light Signaling.

ABSTRACT: The mechanosensitive ion channel PIEZO plays an important role in root growth. Magnetic fields (MF) and blue light are both known to have broad influence on plant growth as physical environmental factors; however, whether the PIEZO gene responds to MF and blue light to regulate root growth remains unclear. Here, we demonstrate that Arabidopsis PIEZO regulates root growth in response to both MF and blue light. Mutation of PIEZO led to a significantly shorter root length under MF and blue light. Moreover, PIEZO expression in root tips was up-regulated by a leaf-derived blue light signal in the presence of MF, and PIEZO affected calcium ion influx and auxin transport related to PIN-FORMED3 (PIN3), PIN6, and PIN7 under combined MF and blue light conditions. Genetic analyses revealed that the b
