The invention belongs to the technical field of tobacco genome gene function analysis, and particularly relates to application of a tobacco NtAAP3 gene in tobacco. The tobacco NtAAP3 is related to amino acid transport, and after the tobacco NtAAP3 is silenced, the contents of tyrosine, proline and asparagine in tobacco are obviously reduced, and the total protein content is obviously reduced; and on the other hand, the tobacco NtAAP3 gene is related to adjustment of the content of pigment substances in tobacco, and after the tobacco NtAAP3 gene is silenced, the content of the pigment substances such as chlorophyll a/b, total chlorophyll and carotenoid in tobacco leaves is obviously increased. According to the application, the relationship between the NtAAP3 gene and amino acid regulation, protein content regulation and pigment content regulation is preliminarily determined, and a theoretical foundation is laid for elaborating the functions of the NtAAP3 gene in the aspects of absorption and transport of amino
