The last eleven linkage groups (LGIX - LGXIX) of the consensus S ₁ linkage map aligned to the poplar physical map. The willow consensus S₁ linkage map aligned to the poplar genomic sequence (prefixed with P) based on SNP, microsatellite and AFLP markers with approximate positions of markers given in base pairs (bp) and centimorgans (cM) respectively. Loci that may indicate syntenic disparities are underlined. Willow linkage groups S₁A to S₁F that could not be aligned to the poplar genome are also shown. Markers showing segregation distortion are indicated by asterisks on the willow map (one asterisk: P < 0.1, two asterisks: P < 0.05, three asterisks: P < 0.01: four asterisks: P < 0.005, five asterisks: P < 0.001, six asterisks: P < 0.0005, seven asterisks: P < 0.0001). Two inversions are indicated by boxes.
