COLD STRESS-RESPONSIVE CRTINTP GENE AND USE THEREOF

摘要

An objective of the present invention is to isolate and identify a gene encoding the polypeptide that interacts with calreticulin (CRT), and to provide the gene and the use thereof. Specifically, an objective of the present invention is to provide the CRTintP gene, the transformed plants comprising the CRTintP gene, and a method of producing these transformed plants. The present inventors successfully detected a group of CRT-interacting genes using the yeast two-hybrid method. As a result, the present inventors detected the polynucleotide encoding the CRT-interacting polypeptide (named as CRTintP). Furthermore, the present inventors isolated the full-length cDNA encoding the CRTintP and revealed that the gene encoding the cDNA was novel. It was found that the expression of the CRT and CRTintP genes was significantly increased following application of cold stress in rice leaves.
