Cotton gene expression profile after feeding by Acyrthosiphon gossypii (Acy) and/or Aphis gossypii (A). FPKM, reads per kilobase million mapped reads. Different letters on the column indicate significant differences between treatment groups (P < 0.05). There were differences in each treatment when FPKM interval was 15–60 and >60 (P < 0.05), and there was no significant difference when FPKM interval was 0–1, 1–3, and 3–15 (P > 0.05).
