The complete sequence of chloroplast genome of an important medicinal plant, Chamaemelum nobile Linaeus 1785 (Asteraceae).

Chamaemelum nobile L. (Asteraceae), commonly known as Roman chamomile, is a perennial herb with branched rhizomes and multiple leafy stems. The length of the complete cp genome is 149,827 bp, and it comprises 128 genes, including 83 protein-coding genes, 8 ribosomal RNA genes, and 37 transfer RNA genes. By conducting phylogenetic analyses based on chloroplast genomes, we found that C. nobile was more closely related to Matricaria chamomilla var. recutita within the chamomile species. This finding contributes to a better understanding of the phylogenetic relationship between C. nobile and other species.
