Complete chloroplast genome sequence of Coyote tobacco (Nicotiana attenuata, Solanaceae)

摘要

AbstractIn this study, we announce the complete chloroplast genome sequence of Nicotiana attenuata. The genome sequence of 155,941?bp consists of two inverted repeat (IRa and IRb) regions of 25,438?bp each, a large single-copy (LSC) region of 86,513?bp and a small single-copy (SSC) region of 18,524?bp. The overall GC content is 37.9% and the GC contents of LSC, IRs, and SSC are 36%, 43.2%, and 32.1%, respectively. The plastome with 129 annotated unique genes includes 84 protein-coding genes, 37 tRNA genes, and 8 rRNA genes. Using the whole chloroplast genome sequences alignment of 16 Solanaceae species a phylogenetic hypothesis is presented validating the position of N. attenuata within Nicotianeae.
