Extended Data Fig. 6: The structure of sucrose synthase (Sus) gene in Pima90 and NDM8, and expression analysis of different stages in cotton fiber development.

a, Comparison of Sus gene sequences among ancestral diploid species and cultivated tetraploid cottons. b, The conservative structures of the Sus in Pima90 and NDM8, respectively. The blue shadow rectangle indicated transmembrane region within GbM_D13G2394. c, The transcriptome of Sus gene in cotton varieties with different fiber quality during fiber developmental stages. The Sus in Pima90 with super fiber quality showed higher expression level than that in NDM8 (good fiber quality) and ND601 (common fiber quality).
