Beschreibung
Zusammenfassung:	The invention belongs to the technical field of genetic engineering, and particularly relates to an NtMYC2a gene mutant for adjusting nicotine content of tobacco leaves and application of the NtMYC2a gene mutant. The nucleotide sequence of the NtMYC2a gene mutant is as shown in SEQ ID NO: 2, and the NtMYC2a gene mutant is obtained by mutating the 490th nucleotide of a tobacco NtMYC2a gene with the nucleotide sequence as shown in SEQ ID NO: 1 from G to T; or the nucleotide sequence of the tobacco NtMYC2a gene is shown as SEQ ID NO: 3, and the tobacco NtMYC2a gene is obtained by mutating the 490th nucleotide of the tobacco NtMYC2a gene with the nucleotide sequence shown as SEQ ID NO: 1 into A from G; or the nucleotide sequence of the tobacco NtMYC2a gene is shown as SEQ ID NO: 4, and the tobacco NtMYC2a gene is obtained by mutating C into T from the 503rd nucleotide of the tobacco NtMYC2a gene with the nucleotide sequence shown as SEQ ID NO: 1. The NtMYC2a gene mutant can adjust the nicotine content in tobacco
