Figure 4

Integrated physical map of the short arm of wheat chromosome 1BS. The anchored 1BS scaffolds are shown as colored rectangles, with the rectangle length corresponding to the estimated scaffold length scaled to the total length of 1BS. Each color corresponds to one of the five bins (I to V) established based on the synteny of 1BS and Brachypodium Bd2, rice Os5 and sorghum Sb9 orthologous regions. The black segments correspond to the heterochromatic regions identified by C-bending. The fraction lengths from the centromere or the Nor are indicated on the left of the chromosome arm. Four black vertical lines (on the right) correspond to 1S GenomeZipper (from 0 at the bottom to 10 Mb at the top, scaled according to Brachypodium Bd2), rice Os5 (from 0 at the top to 8.8 Mb at the bottom), sorghum Sb9 (from 0 at the top to 15.5 Mb at the bottom) and Brachypodium Bd2 (from 30 Mb at the bottom to 40 Mb at the top). Each gray line starting in a wheat scaffold and ending on the 1S GenomeZipper represents a gene assigned to the scaffold for which an orthologous gene on 1S GenomeZipper was identified. The homologous relationships between Os5, Sb9 and Bd2 are also shown by gray lines. Mb, megabase; Nor, nucleolar organizing region.
