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.

远离盐：SMB-AUX1 的故事

Zheng等人（2024年）的研究发现了一个定位于拟南芥根帽的NAC转录因子SOMBRERO（SMB），它对根的半向性至关重要。SMB 通过在侧根帽（LRC）中建立不对称的辅助素分布和维持辅助素流入载体基因 AUX1 的表达来影响根的半向性。这一机制导致根系定向弯曲，远离高盐度区域。研究结果表明，SMB-AUX1-auxin 模块是根帽信号转导和根系向卤反应的关键中介。

期刊介绍： Transgenic Research focusses on transgenic and genome edited higher organisms. Manuscripts emphasizing biotechnological applications are strongly encouraged. Intellectual property, ethical issues, societal impact and regulatory aspects also fall within the scope of the journal. Transgenic Research aims to bridge the gap between fundamental and applied science in molecular biology and biotechnology for the plant and animal academic and associated industry communities. Transgenic Research publishes -Original Papers -Reviews: Should critically summarize the current state-of-the-art of the subject in a dispassionate way. Authors are requested to contact a Board Member before submission. Reviews should not be descriptive; rather they should present the most up-to-date information on the subject in a dispassionate and critical way. Perspective Reviews which can address new or controversial aspects are encouraged. -Brief Communications: Should report significant developments in methodology and experimental transgenic higher organisms
