Gene encoding for a transcription factor which regulates the expression of defense related genes in rice and method for inducing the systemic acquired resistance by using this gene

摘要

PURPOSE: Provided are gene encoding for a transcription factor which regulates the expression of defense related genes in rice and method for inducing the systemic acquired resistance by using this gene. In particular, provided is Oryza sativa ethylene response element binding protein(OsEREBP), a transcription factor which regulates the expression of defense related genes in rice. CONSTITUTION: The method of selecting OsEREBP comprises: treating the known systemic acquired resistance inducer, benzo-1,2,3-thiadiazole-7-carbothioic acid-S-methyl ether (BTH) to produce mRNA which is related to induction of systemic acquired resistance; transcribing the mRNA to obtain cDNA clone by using a transcriptase; selecting cDNA clone capable of being amplified by BTH treatment using the cDNA as a probe; and confirming a OsEREBP by analyzing nucleotide sequence and homology of cDNA clone. The nucleotide sequence of OsEREBP is represented by SEQ ID NO:1.
