Abstract
The GL1 gene is required for the initiation of differentiation of hair cells (trichomes) on the crucifer, Arabidopsis thaliana. This gene has been localized to a 4.5 kb DNA fragment by molecular complementation of gl1 mutants. DNA sequence analysis has shown that the protein encoded by GL1 contains a Myb DNA-binding motif. Southern analysis and subsequence analysis of isolated lambda clones has established that GL1 is a member of an extensive myb gene family in Arabidopsis. The putative GL1 promoter directs the expression of the GUS reporter gene in non-trichome-bearing structures that appear to be stipules. This pattern of expression suggests that GL1 may control the synthesis of a diffusible signal that activates the developmental pathway for trichome differentiation.
