Enhancement of the rootless phenotype of the arf5-2 mutant by dof5.8 mutations. (A) The positions of T-DNA insertions and transcript levels of Dof5.8 in the dof5.8-1 and dof5.8-2 mutant lines. The black box indicates the exon, and the positions of the three amplicons (a–c) are shown below. Nucleotide numbers are given relative to the translation start codon. The transcript levels in wild-type A. thaliana (Col) were set to 1. Data are shown as the means ±SD (n=3). (B) The percentages of the seedlings with the rootless phenotype from segregating populations of arf5-2 single and arf5-2 dof5.8 double mutants. Populations derived from parental plants heterozygous for the arf5-2 allele in the wild-type, dof5.8-1 homozygous or dof5.8-2 homozygous background were analysed.
