Activation tagging library construction and mutant phenotype analysis
Published online by Cambridge University Press: 03 March 2009
Abstract
Activation tagging plays an important role in plant genomics studies. In this paper, an activation tagging library containing 50 000 Basta-resistant lines was constructed by mediated transformation of the mutant bzr1-D of Aribidopsis thaliana. Among these transformants, 47 lines showed obvious phenotypes, including late flowering time, dwarf growth habit, changed leaf shape, longer leaf petiole, leaves lacking trichomes, sterility and no kink between stem/leaf. Some T-DNA flanking sequences were obtained by TAIL (thermal asymmetric interlaced) and nested PCR. Results showed that the mutants contained one to three T-DNA insertions. The insertions were distributed in the first, fourth and fifth chromosomes of the genome.
