Nucleotide sequence encoding the homeobox-leucine zipper protein HAT22 (HD-ZIP protein 22) derived from Japanese pine and juvenile and methods of use

摘要

The present invention relates to isolated polynucleotides encoding the homeobox-leucine zipper protein HAT22 (HD-ZIP protein 22) derived from the plants Shimatsuna and Couma, and corresponding polypeptides derived therefrom. The present invention provides a regulated nucleic acid encoding a homeobox-leucine zipper HAT22 polypeptide or homologue thereof having the ability to modify, preferably increase / enhance fiber length, plant height, and / or plant biomass. It also relates to a plant having expression. More specifically, the present invention relates to polypeptides having homeobox-leucine zipper protein HAT22 activity, polynucleotides encoding these polypeptides, and methods of making and using these polynucleotides and polypeptides. The present invention further provides vectors, expression constructs, and host cells comprising and / or consisting of the nucleotide sequence of homeobox-leucine zipper protein HAT22 (HD-ZIP protein 22). The invention also provides methods for producing the proteins and methods for modifying the proteins to improve their desired characteristics. The proteins of the invention can be used in a variety of ways, including increasing / enhancing fiber length, plant height, and biomass of plants, and fiber yield. [Selection figure] None
