ZmbHLH164 confers mercury tolerance in maize by modulation of mercury accumulation and ROS homeostasis.
Mercury (Hg) is a highly toxic heavy metal that poses a significant threat to crop productivity. Although bHLH transcription factors are known to regulate plant stress responses, their functions in maize (Zea mays) under Hg stress remain largely unexplored. Here, we identify ZmbHLH164, a maize bHLH gene transcriptional...
