Chitinase coding for a DNA molecule preferentially expressed in cotton fibers during the deposition of the secondary cell wall and the corresponding promoter.

摘要

Molecule isolated nucleic acid cotton plants encoding an endogenous chitinase cotton, wherein the nucleic acid molecule is expressed preferentially in fibers during the deposition of the secondary wall and wherein the nucleic acid molecule: a. It comprises a nucleotide sequence encoding an endogenous cotton chitinase and which hybridizes to a DNA molecule having a sequence according to SEQ. ID. No. 1 under stringent conditions characterized by a hybridization buffer comprising 1 x SSC at a temperature of 61 ° C; b. It has the nucleotide sequence of SEQ. ID. No. 1; or c. encoding the protein or polypeptide having the amino acid sequence of SEQ. ID. Do not.
