Fig. 6. Expression of anther and tapetum genes in the wild type and dyt1 mutant. (A) Each of the 11 genes, including the controls UBQ1 and MYB4, show either normal or increased expression in the dyt1 mutant background compared with the wild type. (B,C) Twenty-one genes show significantly decreased expression in the dyt1 mutant background. (D) Real-time PCR of selected anther genes in both wild-type and dyt1 backgrounds. (E) Effects of overexpression of DYT1 on selected anther genes. No significant effects were observed by DYT1 overexpression, even though the DYT1 expression levels were elevated. (F) Expression pattern of selected putative regulatory genes in spl, ems1 and dyt1 background.
