Direct transcriptional activator of some late fatty acid biosynthetic genes and lipogenic genes; significant decreases in the amount of major cutin monomers produced by triple mutant wri1wri3wri4 flowers. the main flower cutin monomer (10,16-dihydroxypalmitate) was decreased by more than 50%. Significant decrease in 18:2 DCA in inflorescence stem cutin of triple mutant. wax production was not affected by the triple mutant.
