摘 要：Arsenic(As)is a toxic heavy metal that can accumulate in crops,posing a health threat to *** genetic mechanism of As accumulation is ***,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 *** kernels had the lowest As content among different maize ***-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 *** As content-related QTLs in maize kernels were detected in the 1.07-1.08chromosomal *** the same genomic region,one QTL for Zn content in maize kernels and two QTLs related to drought tolerance were *** the 4.05genomic region,qLAC4a was consistent with one QTL for Hg accumulation from our previous *** results indicated that pleiotropic effects operate for some As content-related QTLs in maize tissues,and the As content in maize tissues could be altered by genetic *** would be possible to maintain the demand for safe com and to decrease the As content in As-contaminated soil simultaneously by selecting and breeding As-pollution-safe cultivars.
