SEED-SPECIFIC PROMOTER IN COTTON

摘要

The present application discloses a(n) (isolated) nucleic acid sequence comprising a nucleotide sequence selected from (a) SEQ ID NO: 1 or a fragment thereof, wherein said fragment comprises at least 400 consecutive nucleotides of SEQ ID NO: 1 and has seed-specific promoter activity; (b) a nucleotide sequence with at least 80% sequence identity with SEQ ID NO: 1 and having seed-specific promoter activity; (c) a nucleotide sequence hybridizing under stringent conditions to the nucleotide sequence of (a) or (b); and (d) a nucleotide sequence complementary to the nucleotide sequence of any one of (a) to (c). Further disclosed herein is a chimeric gene comprising the (isolated) nucleic acid described herein operably linked to a nucleic acid coding for an expression product of interest, and optionally a transcription termination and polyadenylation sequence. Also disclosed herein are a vector, a transgenic plant cell, a transgenic plant and a seed as characterized in the claims. Methods disclosed herein relate to the production of a transgenic plant, growing cotton, producing a seed, effecting seed-specific expression of a product in cotton and of altering fiber properties in a cotton plant as characterized in the claims.
