Abstract

The present application discloses a chimeric gene comprising a promoter region consisting of the nucleotide sequence of SEQ ID NO: 1 from nucleotide 1 to nucleotide 1437 operably linked to a nucleic acid coding for an expression product of interest, and a transcription termination and polyadenylation sequence. Also disclosed herein are a vector, a transgenic plant cell, a transgenic plant and a seed comprising such a chimeric gene. Methods disclosed herein relate to the production of a transgenic plant, growing cotton, producing a seed, effecting fiber-preferential expression of a product in cotton and of altering fiber properties in a cotton plant using the chimeric gene described.
