摘要
Dear Editor,Gene regulation in model organisms is critical for gene function analysis and is thus essential for human health and agricultural production. Therefore, several molecular tools have been developed to regulate gene expression at the transcriptional and post-transcriptional levels. In recent years, the transcription activator-like effector （TALE）, which is predominantly found in Xanthomonas.
