FIGURE 4.

A molecular regulatory network of cotton fiber development. In the schematic, arrows indicate positive regulation; symbols of ‘T’ indicate negative regulation; lines indicate receptor or interaction; three tightly connected rectangles indicate tri-molecular complexes; red letters in clouds indicate phytohormones. Et, ethylene; ABA, abscisic acid; GA, gibberellin; JA, jasmonic acid; ROS, reactive oxygen species. “Gh” before gene symbols was omitted for space. The detailed information of the genes and their functions in cotton fiber development is listed in Supplementary Table S8.
