摘要： Gossypium hirsutum has proven difficult to sequence owing to its complex allotetraploid (A(t)D(t)) genome. Here we produce a draft genome using 181-fold paired-end sequences assisted by fivefold BAC-to-BAC sequences and a high-resolution genetic map. In our assembly 88.5% of the 2,173-Mb scaffolds, which cover 89.6%similar to 96.7% of the A(t)D(t) genome, are anchored and oriented to 26 pseudochromosomes. Comparison of this Gossypium hirsutum A(t)D(t) genome with the already sequenced diploid Gossypium arboreum (AA) and Gossypium raimondii (DD) genomes revealed conserved gene order. Repeated sequences account for 67.2% of the AtDt genome, and transposable elements (TEs) originating from D-t seem more active than from A(t). Reduction in the A(t)D(t) genome size occurred after allopolyploidization. The A or A(t) genome may have undergone positive selection for fiber traits. Concerted evolution of different regulatory mechanisms for Cellulose synthase (CesA) and 1-Aminocyclopropane-1-carboxylic acid oxidase1 and 3 (ACO1,3) may be important for enhanced fiber production in Gossypium hirsutum.
