QTL mapping for zinc tolerance at the intra-specific level in Arabidopsis halleri using a F2 progeny

Genetic mechanisms of local adaptation are still largely unknown. Our work addressed this question by investigating the genetic architecture of zinc tolerance, as a major trait involved in local adaptation to metal-polluted environments, in Arabidopsis halleri. We assumed that QTLs of local adaptation could be detected in a non-metallicolous x metallicolous F2 progeny.
