For Nicotiana, with 75 naturally occurring species (40 diploids and 35 allopolyploids), we produced 4656bp of plastid DNA sequence for 87 accessions and various outgroups. The loci sequenced were trnL intron and trnL-F spacer, trnS-G spacer and two genes, ndhF and matK. Parsimony and Bayesian analyses yielded identical relationships for the diploids, and these are consistent with other data, producing the best-supported phylogenetic assessment currently available for the genus. For the allopolyploids, the line of maternal inheritance is traced via the plastid tree. Nicotiana and the Australian endemic tribe Anthocercideae form a sister pair. Symonanthus is sister to the rest of Anthocercideae. Nicotiana sect. Tomentosae is sister to the rest of the genus. The maternal parent of the allopolyploid species of N. sect. Polydicliae were ancestors of the same species, but the allopolyploids were produced at different times, thus making such sections paraphyletic to their extant diploid relatives. Nicotiana is likely to have evolved in southern South America east of the Andes and later dispersed to Africa, Australia, and southwestern North America.

从多个质体 DNA 区域推断烟草(茄科)的系统发育关系。
对于烟草属,有 75 个天然物种(40 个二倍体和 35 个异源多倍体),我们为 87 个种质和各种外类产生了 4656bp 的质体 DNA 序列。测序的基因座是 trnL 内含子和 trnL-F 间隔区、trnS-G 间隔区和两个基因 ndhF 和 matK。简约性和贝叶斯分析得出了二倍体的相同关系,并且这些关系与其他数据一致,从而产生了目前对该属最有支持的系统发育评估。对于异源多倍体,母系遗传线是通过质体树追踪的。烟草和澳大利亚特有部落花尾科形成姐妹对。 Symonanthus 是花尾科其他植物的姐妹。烟草属。绒毛科是该属其他物种的姐妹。 N. sect 异源多倍体物种的母本。 Polydicliae 是同一物种的祖先,但异源多倍体是在不同时间产生的,因此使这些部分与其现存的二倍体亲戚并系。烟草很可能在安第斯山脉以东的南美洲南部进化,后来传播到非洲、澳大利亚和北美西南部。
