The isolated polypeptide, construction of recombinant host cell nucleic acid, methods of producing the polypeptide to produce a mutant of a precursor cell.To inhibit the expression of a polypeptide having the activity of xylanase in a cell, to produce a protein and a cotendo material to degrade xylan, cell mutant, transgenic plant.Part of the plant or plant cell, and RNA molecule inhibiting double filament

摘要

The present invention relates to isolated polypeptides having xylanase activity and isolated polynucleotides encoding the polypeptides. The invention also relates to nucleic acid constructs, vectors, and host cells comprising the polynucleotides as well as methods of producing and using the polypeptides.
