Schematic model of TALE superfamily genes involved in the regulation of cotton growth and development. In plants, TALE proteins always form heterodimers (BEL1-like proteins binding KNOX proteins) to regulate plant growth and development. KNAT7 plays a central role in regulating cotton fiber SCW biosynthesis and can interact with BEL1-like members (including BEL1, BLH1, BLH5, and BLH6) and other TFs (including OFP1, OFP4 and MYB75) to form a complex. Moreover, the TALE heterodimers are often directly targeted by GhMYB46 and GhFSN1 genes. Downstream of this pathway, TALE heterodimers directly bind the promoters of some lignin and cellulose biosynthesis genes to regulate the thickening of fiber secondary cell walls. The solid lines represent the findings of this study and the dashed lines represent the discoveries of previous studies
