Comment
Allelic variation at the promoter of Almt-D1 is associated with differences in Al tolerance. Molecular and pedigree analysis suggest that Al resistance in modern wheat germplasm is derived from several independent sources (Raman et al., 2008)
QTL: Atlas 66/Century: A QTL in the region Xdgm125-4DL - Xwmc331-4DL accounted for nearly 50% of the phenotypic variation in root growth rate in hydroponic solution (Ma et al, 2005) An Al-activated malate transporter (LMT1) was earlier mapped to the same location (Sasaki et al., 2004)
Atlas 66 (insensitive)/Chisholm (sensitive) RILs: One QTL, located in chromosome 4DL, corresponded to ALMT1 and accounted for 50% of the phenotypic variation. A second QTL was located on 3BL(R2 = 0.11); nearest marker Xbarc164-3B. Both QTLs were verified in Atlas/Century (Zhou et al., 2007)
FSW (A1 tolerant) / ND35 (A1 sensitive): 3 QTLs for tolerance, Qalt.pser-4DL co-segregating with Xups4, a marker for the promoter of the ALMT1 gene, Qalt.pser-3BL (Xbarc164-3B - Xbarc344-3B) and Qalt.pser-2A (Xgwm515-2A - Xgwm296-2A) (Cai et al., 2008)
In D genome introgression lines of Chinese Spring a major QTL was located in the interval Xgwm125-4D - Xgwm976-4D, R2=0.31, probably coinciding with Alt2. A second QTL from CS, Qaltcsipk-3B, R2=0.49, occurred in interval Xgwm1029-3BL - Xgwm1005-3BL in a CS / CS (Synthetic 3B) population (Navakode et al., 2009)
