Proposed model for the involvement of TCP15 and other class-I TCPs in the stimulation of stamen filament elongation by GAs. GAs induce expression of TCP15 and activate class-I TCP proteins through GA-dependent DELLA degradation. Class-I TCP proteins induce SAUR63 and related genes by direct interaction with TCP target sites present in their promoters. SAUR63 proteins stimulate stamen filament elongation.
