Characterization of the complete plastid genome of fireweed, Epilobium angustifolium, Shaanxi, China

Abstract

In this article, we studied the complete chloroplast genome of Fireweed, Epilobium angustifolium, an essential herbaceous perennial species of the genus Epilobium (Onagraceae), we used Illumina sequencing platform to characterize its whole plastid genome sequence. The results showed that its whole plastid genome is a typical qudaripartite circular molecule with 161,199 bp in total length, which contains a large single-copy region of 89,076 bp, a small single-copy region of 17,321 bp, and two inverted repeat regions of 27,401 bp. We identified 130 genes, 85 protein-coding genes, 37 tRNA, and 8 rRNA genes within this genome. The GC content in the chloroplast genome, LSC region, SSC region, and IR region were 38.1, 36.3, 33.1, and 42.7%, respectively. Phylogenetic analysis indicated that this plant was placed as a sister to the congeneric Epilobium ulleungensis, the two species were clustered into a clade with high bootstrap support.
