Additional file 3 of Contrasting genetic variation and positive selection followed the divergence of NBS-encoding genes in Asian and European pears

Additional file 3. NBS-encoding genes in pear disease resistance QTL regions. A total of 18 QTL were detected from previous study [13, 16, 17, 22, 33–35]. The primers of SSR markers in QTL were used to detect the marker location on the reference genome [1, 32]. Markers upstream and downstream 500 kbp were selected to identify the presence of NBS genes related to these QTL.
