Iron (Fe) is an essential micronutrient for humans, and iron deficiency is the most common micronutrient deficiency worldwide. Research on the genetic basis of iron concentration in maize kernels will provide guidance for the development of iron-rich crops, a major breeding goal to address iron deficiency. The maize Yellow Stripe 1 (ZmYS1) gene encodes a specific transporter that takes up Fe(III)-phytosiderophore complexes into roots. Here, we re-sequenced ZmYS1 gene in 88 elite maize inbred lines and detected the association between the nucleotide polymorphisms and micronutrient concentrations in maize kernels. Our analyses detected a total of 71 sequence variants in ZmYS1, including 61 single nucleotide polymorphisms (SNPs) and 10 insertions and deletions (indels), from the tested population. Fourteen haplotypes, which encode 13 different ZmYS1 proteins, are classified based on the polymorphism in the coding region. Numerous polymorphic sites in maize ZmYS1 locus were found in linkage disequilibrium (LD) that decay with increasing physical distance, and at least 14 recombination events have contributed to the LD and haplotype diversity of this gene. Additionally, our data show that a non-synonymous site in the ZmYS1 gene is associated with the maize kernel Fe concentration, and two other non-synonymous sites with Zinc (Zn) concentration. These findings suggest that the polymorphism in maize ZmYS1 locus may be used for biofortifying kernel mineral concentrations in maize breeding programs.
