To provide a new tomato mutant with an increased lycopene content without a decreased β-carotene content, and a method for producing the same. [Solution] We discovered that by introducing a mutation into the tomato nitrate transporter gene (NPF1 gene) and expressing a mutant protein with a large deletion in the C-terminal region, it is possible to increase the lycopene content in tomatoes without reducing the β-carotene content.

The application discloses application of VvNRT1.1 and VvCNGC15 proteins in improving nitrogen utilization rate of grape, and belongs to the technical field of plant genetic engineering and molecular breeding. The application proves that the VvNRT1.1 and VvCNGC15 proteins directly physically interact, and overexpression of the VvNRT1.1 or VvCNGC15 can improve the absorption and assimilation efficiency of nitrate nitrogen of grape. Therefore, the VvNRT1.1 and VvCNGC15 can be used as key molecular targets for improving nitrogen utilization rate, and have potential application value.

In the present invention, it is found that the content of lycopene can be increased without decreasing the content of β-carotene in tomatoes by introducing a mutation into a nitrate transporter gene (NPF1 gene) of tomatoes to express a mutant protein in which a C-terminal region is largely deleted.
