| Research Abstract |
By screening an activation tagging library, we isolated an Arabidopsis mutant,chestnut, which has a severe bushy phenotype resulting from the formation ofextra-axillary meristems. Compared to the Col-0 wild type, chestnut showed a 10-30-fold increase in the expression of a transcription factor gene than. The mutation in chestnut leads to the upregulation of PR1 genes, which are required for plant defense responses. This result suggests that the defense responses of plants and the formation of axillary meristems might share some common factors.
