Unlock the potential of plant genes: This study introduces activation tagging as a powerful tool for gene discovery in *Arabidopsis*. By using T-DNA vectors containing multimerized transcriptional enhancers from the cauliflower mosaic virus (CaMV) 35S gene, researchers generated thousands of transformed plants and identified over 30 dominant mutants with diverse phenotypes. Analysis revealed that overexpressed genes are typically located near the CaMV 35S enhancers, suggesting a direct activation mechanism. Interestingly, in some cases, the enhancers primarily enhanced the endogenous expression pattern rather than causing ectopic expression. This method provides a valuable approach for identifying genes involved in various plant processes and understanding the regulatory mechanisms that control gene expression. The findings have important implications for plant biotechnology and crop improvement.
Published in Plant Physiology, this paper is well-suited to the journal's focus on plant biology and biochemistry. By describing a novel method for gene discovery in Arabidopsis, the study provides valuable tools and insights for plant researchers. The findings on activation tagging and its effects on gene expression contribute to the understanding of fundamental processes in plant development and physiology.
