Abstract

The study by Zheng et al. (2024) identifies a NAC transcription factor, SOMBRERO (SMB), localized in the root cap of Arabidopsis, which is essential for root halotropism. SMB influences root halotropism by establishing asymmetric auxin distribution in the lateral root cap (LRC) and maintaining the expression of the auxin influx carrier gene AUX1. This mechanism leads to directional root bending away from high salinity areas. The findings reveal the SMB-AUX1-auxin module as a crucial mediator in root cap signaling and root halotropic response.
