Naturally colored cotton (NCC; Gossypium spp.) does not require additional chemical dyeing and is an environmentally friendly textile material with great research potential applications. Our previous study using linkage association mapping identified TRANSPARENT TESTA 2 (Gh_TT2) as acting on the proanthocyanin synthesis pathway. However, limited information available about genetic regulatory network of NCC. Here, we verified effectiveness Gh_TT2 roles red foliated mutant gene (Re) in pigment formation deposition brown fiber (BFC). Variations derived from interspecific hybridization between barbadense acc. Pima 90-53 hirsutum Handan208 resulted expression differences, thereby causing phenotypic variation. Additionally, MYB-bHLH-WD complex was found to be negatively modulated by 16/ARABIDOPSIS BSISTER (TT16/ABS). RNA-seq suggested that differential homologous genes key enzymes pathway strongly contributes color rendering natural dark light cotton. proposes a model BFC, which will provide theoretical guidance for improvement
