“…However, the issue of complete mitogenome assembly is gradually being addressed with the use of long-read sequencing methods. Although many organellar genomes have been published from the Asteraceae, most studies have been limited to phylogenetic research, without further exploring the evolutionary patterns within a species or how organellar genome evolution correlates with changes in nuclear genome ploidy (Xia et al, 2016;Kim et al, 2018;Won et al, 2018;Feng et al, 2020;Xia et al, 2021a;Xia et al, 2021b;Yu et al, 2021;Masuda et al, 2022).…”

Chrysanthemum indicum, a species native to Eastern Asia is well known as one of the progenitor species of the cultivated Chrysanthemum which is grown for its ornamental and medicinal value. Previous genomic studies on Chrysanthemum have largely ignored the dynamics of plastid genome (plastome) and mitochondria genome (mitogenome) evolution when analyzing this plant lineage. In this study, we sequenced and assembled the plastomes and mitogenomes of diploid and tetraploid C. indicum as well as the morphologically divergent variety C. indicum var. aromaticum. We used published data from 27 species with both plastome and mitogenome complete sequences to explore differences in sequence evolution between the organellar genomes. The size and structure of organellar genome between diploid and tetraploid C. indicum were generally similar but the tetraploid C. indicum and C. indicum var. aromaticum were found to contain unique sequences in the mitogenomes which also contained previously undescribed open reading frames (ORFs). Across Chrysanthemum mitogenome structure varied greatly but sequences transferred from plastomes in to the mitogenomes were conserved. Finally, differences observed between mitogenome and plastome gene trees may be the result of the difference in the rate of sequence evolution between genes in these two genomes. In total the findings presented here greatly expand the resources for studying Chrysanthemum organellar genome evolution with possible applications to conservation, breeding, and gene banking in the future.

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.
