CHITINASE ENCODING DNA MOLECULE FROM COTTON EXPRESSED PREFERENTIALLY IN FIBERS DURING SECONDARY CELL WALL DEPOSITION AND THE CORRESPONDING PROMOTER

The present invention relates to an isolated nucleic acid molecule encoding an endogenous cotton chitinase and its promoter, which are preferentially expressed in fibers during secondary wall deposition. The polypeptide encoded by the nucleic acid molecule, a DNA construct linking the isolated nucle...

Beschreibung
Zusammenfassung:	The present invention relates to an isolated nucleic acid molecule encoding an endogenous cotton chitinase and its promoter, which are preferentially expressed in fibers during secondary wall deposition. The polypeptide encoded by the nucleic acid molecule, a DNA construct linking the isolated nucleic acid molecule with a promoter, the DNA construct incorporated in an expression system, a host cell, a plant, or a plant seed are also disclosed. The present invention also relates to a DNA construct linking the isolated promoter with a second DNA as well as expression systems, host cells, plants, or plant seeds containing the DNA construct. Methods of imparting resistance to insects and fungi, regulating the fiber cellulose content, and methods of expressing a gene preferentially in fibers during secondary wall deposition are also disclosed.
