Variations in Hd1 and its relationship with Hd3a expression levels. (A) Nucleotide polymorphism in the Hd1 coding region. The nucleotide sequences in the cultivars were compared with those of Nipponbare (indicated as Type 1). Polymorphic nucleotides are indicated in black or grey. Amino acid substitutions caused by nucleotide polymorphism are indicated, frame shift is indicated as F.S. Polymorphisms labeled in black caused loss of function alleles. Numbers indicate position from ATG start codon. The number of cultivars containing each type of allele is indicated in the right column. Shaded boxes represent the Hd1 zinc finger domain and CCT domain. (B) Correlation of flowering time with RFT1 and Hd3a RNA levels of cultivars carrying functional (blue dots) or non-functional Hd1 alleles (red dots). RNA levels were determined by real-time RT-PCR and shown as natural logarithms.
