Key impact of Vgt1 on flowering time adaptation in maize:: Evidence from association mapping and ecogeographical information

An association study conducted on 375 maize inbred lines indicates a strong relationship between Vgt1 polymorphisms and flowering time, extending former quantitative trait loci (QTL) mapping results. Analysis of allele frequencies in a landrace collection supports, a key role of Vgt1 in maize altilatitudinal adaptation.
