Comprehensive Assembly and Comparative Analysis of Chloroplast Genome and Mitogenome of Prunus salicina var. cordata

Abstract

Background: Prunus plants are widely distributed across Asia and Europe, yet their intricate phylogenetic relationships pose significant challenges for systematic studies and interspecies identification. Objectives: To clarify the mitochondrial and chloroplast genomes of Prunus salicina var. cordata, and to reveal its evolutionary relationship and historical gene flow with domesticated cherries. Methods: In this study, we assembled, annotated, and analyzed the first mitochondrial and chloroplast genomes of P. salicina var. cordata, a species within the Prunus genus. Results: The mitochondrial genome was found to be 484,858 base pairs in length, exhibiting a typical circular conformation. Phylogenetic analysis revealed a close evolutionary relationship between P. domestica and P. salicina, suggesting historical gene flow between these two species last genomes; mitochondrial genomes; phylogeny analysis. Conclusions: To provide a genomic basis for resolving the phylogenetic controversies within the Li-associated plants, elucidating their evolutionary mechanisms, and formulating breeding strategies. Keywords: Prunus salicina var. cordata, chloroplast genomes, mitochondrial genomes, phylogeny analysis
