Reference	Yu L et al. (2014) A consensus map for Ug99 stem rust resistance loci in wheat. Theoretical and Applied Genetics 127:1561-1581.
Remark	The location on the 2014 Ug99 Consensus Map is approximate. Curator note, Aug. 2018. The position of Sr40 on 2B is not clear in TAG-127-1561. Table 1 assigns Sr40 to wPt-0100 and wPt-9402 at positions 17.7 and 57.8 resp. Placement on the map on Figure 2 is approx 80cM. Curator note, Aug. 2018. The gene on 2B of the Ug99 2014 Consensus maps is placed on the GrainGenes map to approximate its position on Figure 2 of TAG-127-1851 rather than placed to co-align with the above mentioned DArT markers in Table 1.
