A NOVEL NICOTINE BIOSYNTHETIC GENE AND USE THEREOF

摘要

It relates to a novel Putrescine N-methyltransferase 1b (PMT1b) gene consisting of the nucleotide sequence of SEQ ID NO: 1 and its use. When the expression of the gene is suppressed together with the PMT1a, PMT2, PMT3 and PMT4 genes, nicotine biosynthesis of plants may be suppressed, and thus plant cells with no or low nicotine content may be produced.
