Figure 1

Integrated genetic, physical and transcript map of chromosome 12 (top part). Note: Three columns are displayed in the figure (left, middle and right). Left column shows the fiber EST unigenes anchored to the chromosome 12; Middle column shows the genetic map, and right column shows the contigs assembled from the positive clones to the genetic markers. The markers in black were used as backbone markers that were derived from an F₂ mapping population (G. hirsutum race "palmeri" and G. barbadense acc. "K101); markers in red (MUSB) were from BAC-end sequence and genetic distance was from the RIL mapping population (G. hirsutum TM-1 × G. barbadense 3–79); markers in green (TMB) were from BAC subcloned sequence and mapped by the TM-1 × 3–79 RIL population; the blue markers were from BC₁ mapping population ('Guazuncho 2' × 'VH8-4602'). Markers in pink at the bottom of the figure were from BC₁ mapping population (TM-1 × (TM-1 × Hai7124). CUN stand for Cotton Unigene Number that was used in the original paper [16]. This figure shows the upper part of the whole figure, for the full image please see additional file 7.
