Abstract

Nicotiana plumbaginifolia Vivianiis 1802 is an annual herb, native to Mexico and South America. It is one of the most widely distributed tobacco species. As a wild tobacco, N. plumbaginifolia has provided several economically important disease-resistance genes to cultivated tobacco. We assembled the complete chloroplast genome of N. plumbaginifolia. The chloroplast genome is 155,945 bp in length, which includes a large single copy region (86,621 bp), a small single copy region (18,528 bp) and two separated inverted repeat regions (25,398 bp). A total of 117 unique genes were annotated, consisting of 84 protein-coding genes, 29 tRNA genes and 4 rRNA genes. Based on chloroplast genomes of 17 Nicotiana species, phylogenetic analyses indicated that N. plumbaginifolia was closely related to N. suaveolens and N. amplexicaulis.
