摘　　要：Gossypium hirsutum,the most widely planted cotton species,its evolution has long been an unsolved puzzle because of its hybrid origin from D-genome and A-genome species.To better understand the genetic component of cotton,Huang et al.recently sequenced and assembled the first A1-genome G.herbaceum,and updated the A2-genome G.arboreum and(AD)1-genome G.hirsutum.On the basis of the three reference genomes,they resolved existing controversial concepts and provided novel evolutionary insights surrounding the A-genome.
