Research Abstract	The outer layer of pollen wall, which is called exine, is made of "sporopollenin" polymer. But its chemical structure remains unknown because it is extremely resistant against nonoxidative degradation. The representative analyzed function of Arabidopsis 3-ketoacyl-CoA synthases and a BAHD acyl transferase for their involvement in exine formation. A BAHD mutant showed a subtle phenotypic change in exine appearance. The BAHD gene, therefore, is suggested to be involved in exine formation.
