BEAR1, a bHLH Transcription Factor, Controls Salt Response Genes to Regulate Rice Salt Response

Abstract Transcription factors play important roles in plant abiotic stresses. However, there are a large number of TF functions rice salt response need to be characterized. Our study identified new transcription factor, BEAR1, acts as regulator response. We used artificial microRNA generate BEAR1 knockdown transgenic rice, and CRISPR gene editing mutant lines. Both lines showed sensitive phenotypes, compared NIP. Transient expression protoplast was confirm the subcellular localization BEAR1. The activity detected by yeast system. induced stress dominantly expressed root at seedling stage spikelet mature stage. regulating controlling levels many salt-related genes, including marker genes ion transporter genes. revealed that
