Abstract: The present disclosure relates generally to nucleic acid constructs comprising a nucleotide sequence comprising one or more pigment producing genes, wherein expression of the nucleotide sequence is under the control of a cotton fibre-specific promoter, and wherein the cotton fibre-specific promoter is capable of driving expression of the nucleotide sequence during two or more fibre development stages, and their use in the production of colour cotton fibre, or for the introduction of one or more pigment producing genes into a cotton plant. The present disclosure further contemplates cotton plants modified to produce cotton fibre, cotton seed, cotton lit, yarn, textiles and associated methods.
