Abstract excerpt
KEY MESSAGE: We found that mutations in a Ca2+-permeable mechanosensitive channel MCA1, an ethylene-regulated microtubule-associated protein WDL5, and a versatile co-receptor BAK1 affect root growth response to mechanical stress. Plant root tips exposed to mechanical impedance show a temporal reduction in the elongation growth. The process involves a transient Ca2+ increase in the cytoplasm followed by ethylene...
