NUCLEOTIDE SEQUENCES AND POLYPEPTIDES ENCODED THEREBY USEFUL FOR MODIFYING PLANT CHARACTERISTICS IN RESPONSE TO COLD

摘要

Methods and materials for modulating cold tolerance levels in plants are disclosed. For example, nucleic acids encoding cold tolerance-modulating polypeptides are disclosed as well as methods for using such nucleic acids to transform plant cells. Also disclosed are plants having increased cold tolerance levels and plant products produced from plants having increased cold tolerance levels.

主权项

1. A method of producing a plant and/or plant tissue, said method comprising growing a plant cell comprising an exogenous nucleic acid, said exogenous nucleic acid comprising a regulatory region operably linked to a nucleotide sequence encoding a polypeptide, wherein the HMM bit score of the amino acid sequence of said polypeptide is greater than about 130, said HMM based on the amino acid sequences depicted in one of FIG. 1, 2, 3, 4, or 5 and wherein said plant and/or plant tissue has a difference in the level of cold tolerance as compared to the corresponding level of cold tolerance of a control plant that does not comprise said nucleic acid.
