Activation tagging is a T-DNA-based approach in. which a series of strong enhancers are positioned next to. the right- or left-hand T-DNA border. Insertion of the. vector near a gene causes up-regulation and dominant. gain-of-function mutations. Several attributes of activation. tagging make it an attractive tool for functional genomics. studies and leading to development of large collections. predominantly in Arabidopsis (Ichikawa et al.
