Abstract excerpt
Genetic variation within a species can result in allelic expression for natural selection or breeding efforts. Here, we identified an iron (Fe) deficiency-inducible gene, AP2-like ABA repressor 1 (MdABR1), in apple (Malus domestica). MdABR1 exhibited differential expression at the allelic level (MdABR131A and MdABR131G) in response to Fe deficiency. The W-box insertion in the promoter of MdABR131A is essential...
