29566653-3	2018	Transcriptome analysis revealed that genes participating in nicotine anabolism (ADC, PMT, MPO, QPT, AO, QS, QPT, A622, BBLs) and nicotine transport (JAT2, MATE1 and 2, NUP1 and 2) showed an upregulated expression in the hybrid, a majority of which demonstrated an overdominant performance.	Nicotine	60-68	putrescine N-methyltransferase 3	Nicotiana tabacum	85-88	
19165623-2	2009	By down-regulation of PMT through three kinds of RNA silencing approaches, the nicotine levels decreased accordingly.	Nicotine	79-87	putrescine N-methyltransferase 3	Nicotiana tabacum	22-25	
16088399-1	2006	Putrescine N-methyltransferase (PMT, EC 2.1.1.53) catalyses the first specific step in the biosynthesis of tropane and nicotine alkaloids.	Nicotine	119-137	putrescine N-methyltransferase 3	Nicotiana tabacum	32-35	
12885861-1	2003	Putrescine N-methyltransferase (PMT) is the first alkaloid-specific enzyme for nicotine and tropane alkaloid formation.	Nicotine	79-87	putrescine N-methyltransferase 3	Nicotiana tabacum	32-35
