Presumed functions of KNS genes. Schematic diagram of exine formation, which is based on previous models (Scott 1994, Paxon-Sowders et al. 1997), and predicted functions of the 12 KNS genes identified in this screening. The diagram indicates where expression of the genes is expected. Note that tapetal cells and pollen mother cells are diploid cells whereas microspores are haploid cells.
