The first complete chloroplast genome for the species-rich genus Anthemis (Asteraceae)

Abstract

Anthemis L. 1753 is a species-rich genus of Asteraceae. It includes species of economic value as ornamental, edible and medicinal plants. We report here the complete chloroplast genome of Anthemis cretica subsp. calabrica (Arcang.) R. Fern. 1975, the first chloroplast genome of any Anthemis species. For the scope, we have used long reads obtained with Oxford Nanopore technology. The assembled plastome is 149,509 bp long and is subdivided in a large single-copy region (LSC, 82,317 bp), a small single-copy region (SSC, 18,212 bp) and two inverted repeat regions (IR: 24,490 bp). It comprehends 136 predicted genes, of which 92 protein-coding genes, 35 tRNAs, and 8 rRNAs. The overall GC content is 37.54%. The position of A. cretica subsp. calabrica in the phylogenetic tree is congruent with those of previous analyses based on a few chloroplast or nuclear regions.
