Model of CAF-1 function in trichome branching. The initiation of branching is regulated by two independent pathways. In the first pathway, Gl3 is a postive regulator and KAK is a negative regulator. In this pathway, endoreduplication triggers trichome branching. In the second pathway, STI is a positive regulator and CAF-1 is a negative regulator. Exogenous sucrose can partly substitute the negative function of CAF-1. CAF-1 is also required for extensive endoreduplication such as in the kak-2 mutant. Images represent trichome phenotypes in the respective mutants.
