Arsenic (As) is a toxic heavy metal that can accumulate in crops,posing a health threat to humans.The genetic mechanism of As accumulation is unclear.Here,quantitative trait locus (QTL) mapping was used to unravel the genetic basis of As accumulation in maize using a recombinant inbred line population derived from the Chinese crossbred variety Yuyu22.The kernels had the lowest As content among different maize tissues.Twenty-eight QTLs were identified at two locations,mostly clustered in chromosomal bins 1.02-1.03,1.07-1.08,4.05,5.03,7.00,and 7.02-7.03.
