In the published article, there were errors in the Results and Discussion sections, as well as Data Sheet 1. These errors became apparent when the seed stock of the doubled-haploid (DH) line WW28450 was subsequently found to be a mixture of two DH lines. These comprised one line that was Drysdale-type non-recombinant for chromosome arm 2BS, and a recombinant line that was Waagan-type for the 2BS WtmsDW interval and Drysdale-type proximally. The authors wrongly interpreted the marker calls to indicate that WW28450 had a deletion of the WtmsDW interval when in fact there was no such deletion.
The following text, located in Results, Further Mapping in the WtmsDW Region and Relationships to Other Fertility Loci, Paragraph two, has been removed:
“The DH line WW28450 carried a spontaneous deletion on chromosome 2B from 104.24 Mb upwards (Supplementary Figure 1), essentially covering the whole of the short arm, including the WtmsDW locus (Figure 3). This line was phenotypically intolerant to heat stress but fully fertile under control conditions (Supplementary Figure 1).”
The following text located in Discussion, WtmsDW Significance and Potential Applications, paragraph five, has been removed:
“The DH line WW28450 carried a deletion of the whole of the short arm of chromosome 2B and was heat intolerant. This suggested that tolerance from 2BS derives from positive gene function(s) (as opposed to absence/reduction of a tolerance suppressor), which is missing/reduced in the intolerance allele. However, 2BS carries additional male fertility loci, including Wptms2 that conditions sterility under high temperatures and/or long days (Figure 3; Guo et al., 2006a), so the implications for WtmsDW are not entirely clear.”
The following text, located in Data Sheet 1, Supplementary Figure 1, Drysdale × Waagan DH mapping line information has also been removed: “Line WW28450 (column CK) was inferred to be a deletion mutant from 104.24 Mb upwards based on 9K SNP marker calls”.
