GENE FOR INCREASING THE PRODUCTION OF PLANT BIOMASS AND/OR SEEDS AND METHOD FOR USE THEREOF

摘要

A technique by which the production of plant biomass can be significantly increased is provided. A protein phosphatase 2C gene having 3 consensus sequences comprising the amino acid sequences shown in SEQ ID NOS: 1-3 from the N-terminal side in such order is over-expressed.

主权项

1. A method for increasing the production of biomass comprising overexpressing in a plant a gene encoding protein phosphatase 2C comprising a protein (a) or (b)′
(a) a protein comprising an amino acid sequence selected from the group consisting of SEQ ID NOS: 7, 36, 42, 48 and 59-65; and (b) a protein comprising an amino acid sequence that has a deletion of one to five amino acids, a substitution of one to five amino acids, an addition of one to five amino acids, or an insertion of one to five amino acids with respect to an amino acid sequence selected from the group consisting of SEQ ID NOS: 7, 36, 42, 48 and 59-65 and having protein phosphatase 2C activity; and thereby increasing the production of biomass as compared to a wild-type plant.
