From: Genetic dissection of Al tolerance QTLs in the maize genome by high density SNP scan
Near-isogenic lines introgressed with qALT6 , using Cateto Al237 and L53 as the donor and recurrent parents, respectively. A) Aluminum tolerance measured as relative seminal root growth after five days under {39} μM Al3+. B) ZmMATE1 relative expression evaluated in root tips after 6 hours of treatment with {39} μM Al3+ (dark gray) and under control condition (light gray). Expression of L53 under controlled condition (−Al) was used as calibrator. C) ZmMATE1 copy-number estimated based on qPCR. Error bars indicate standard deviation.
