Comparative analysis of plastid genomes reveals rearrangements, repetitive sequence features, and phylogeny in the Annonaceae.

ABSTRACT: The Annonaceae stands as the most species rich family in the Magnoliales, a basal group of angiosperms. Widely distributed in tropical and subtropical regions, it holds significant ecological and economic value. The plastid genome (plastome) is often employed in studies related to plant phylogenetics, comparative genomics, evolutionary biology, and genetic engineering. Nonetheless, research progress on plastid genomics in the Annonaceae has been relatively slow. In this study, we analyzed the structure and repetitive sequence features of plastomes from 28 Annonaceae species. Among them, Mitrephora tomentosa and Desmos chinensis were newly sequenced, with sizes of 160,157 bp and 192,167 bp, and GC contents of 38.3% and 38.4%, respectively. The plastome size in the Annonaceae r
