Plant Body Showing Improved Resistance Against Environmental Stress and Method for Producing Same

摘要

[Problem] To impart an improved resistance against environmental stress to a plant body without inducing a delay in the growth or dwarfing of the plant body. [Solution] The present invention clarifies for the first time that Arabidopsis thaliana YC10 interacts with DREB2A. Also, the present invention clarifies for the first time that when a host plant is transformed with Arabidopsis thaliana NF-YC10 gene, the thus obtained transformant has an improved resistance to environmental stress.

主权项

1. A transformed plant showing improved resistance to environmental stress that overexpresses a gene containing a nucleotide sequence selected from the group consisting of:
(1) a nucleotide sequence encoding a protein comprising an amino acid sequence shown by SEQ ID NO: 2, 4, 6, or 8; (2) a nucleotide sequence encoding a protein having 60% or higher sequence homology to the amino acid sequence shown by SEQ ID NO: 2, 4, 6, or 8 and having an ability to bind to DREB2A (dehydration responsive element binding protein 2A) protein; and (3) a nucleotide sequence that hybridizes under stringent conditions with a nucleic acid comprising a nucleotide sequence complementary to a nucleotide sequence shown by SEQ ID NO: 1, 3, 5, 7, 14, 15, 16, or 17 and encodes a protein having the ability to bind to DREB2A protein.
