AP3 and PI regulate the expression of sugar-sensing genes. A, Expression levels of HXK1, HXK2, AIPLT6, and AISTP13 by RT-PCR in 35S∷AP3 and 35S∷PI and ap3-3 and pi-1 mutant flowers. B, Quantified expression levels in 35S∷AP3 and 35S∷PI flowers by RT-PCR. Average expression levels from three replicates were normalized to actin with the wild type scaled to 1. C, Quantified expression levels in ap3-3 and pi-1 mutant flowers by RT-PCR. Average expression levels from three replicates were normalized to actin with the wild type scaled to 1.
