TLDR CNGC14 is crucial for calcium entry needed for root hair growth in plants.
The study identified the Arabidopsis CNGC14 channel as essential for calcium influx necessary for the tip growth of root hairs, with its high expression in root hairs and localization to the plasma membrane facilitating an apical calcium gradient. Mutants lacking CNGC14 had shorter root hairs, highlighting its role in elongation. The research also suggested a potential involvement of CNGC14 in auxin-dependent gravitropism, linking calcium signaling with auxin response, although other channels might also contribute to calcium influx for root-hair growth.
