Application of tobacco Ntab0167450 gene and encoded protein thereof in tobacco polyphenol regulation and control

The invention provides an application of a tobacco Ntab0167450 gene and an encoded protein thereof in tobacco polyphenol regulation, after the expression quantity of the gene is reduced, the content of polyphenols in fresh tobacco subjected to gene editing has no significant difference, and the content of polyphenols in flue-cured tobacco subjected to gene editing is reduced. The tobacco Ntab0167450 gene and the encoded protein thereof disclosed by the invention can be used for adjusting the polyphenol content of tobacco leaves and quickly and efficiently improving the tobacco quality. 本发明提供了一种烟草Ntab0167450基因及其编码蛋白在烟叶多酚调控中的应用，该基因表达量降低后，基因发生编辑的新鲜烟叶中的多酚类物质含量无显著差异，基因发生编辑的烤后烟叶中的多酚类物质含量降低。本发明所述烟草Ntab0167450基因及其编码蛋白可以调节烟叶多酚含量，快速、高效地实现烟草品质改良。
