Nucleotide polymorphisms in Ehd1 promoter and its relationship with flowering time. (A) Nucleotide polymorphism in the Ehd1 promoter. The nucleotide sequences in the cultivars were compared with those of Nipponbare (indicated as Type A). Polymorphic nucleotides are indicated in grey. Numbers indicate position from ATG start codon. The number of cultivars containing each type of allele is indicated in the right column. (B) Correlation of flowering time with RNA levels of Ehd1 in leaves. RNA levels were determined by real-time RT-PCR and shown as natural logarithms. The square of Pearson’s product–moment correlation coefficient is indicated (P < 0,05). Color dots indicate cultivars carrying different types of Ehd1 alleles. (C) Ehd1 RNA levels in cultivars with type A, B or C Ehd1 promoters. RNA levels represented the mean and are shown as natural logarithms. Error bands represent standard deviation.
