摘要

尽管芒果是一种经济上重要的水果，但其叶绿体基因组序列的可用性仍然有限。在本研究中，我们对芒果（Mangifera indica’Guiqi’）和芒果（M. quadriida）的叶绿体全基因组进行了组装、注释和鉴定。籼稻“桂七”（157,780 bp）和四棱稻（158,979 bp）叶绿体基因组均为四分体结构，含有87个蛋白质编码基因、37个tRNA基因和8个rRNA基因，GC含量分别为37.9%和37.8%。系统发育分析证实了籼稻“贵七”的母系起源，并揭示了四裂稻与相似稻亲缘关系最密切，表明存在广泛的杂交和渐近。

Chloroplast genome characteristics and phylogenetic analysis of Mangifera indica L. 'Guiqi' and M. quadrifida Jack (anacardiaceae).

Despite being an economically significant fruit, the availability of Mangifera chloroplast genome sequences remains limited. In this study, we assembled, annotated, and characterized the complete chloroplast genomes of Mangifera indica 'Guiqi' and M. quadrifida. The chloroplast genomes of M. indica 'Guiqi' (157,780 bp) and M. quadrifida (158,979 bp) both exhibit a quadripartite structure, contain 87 protein-coding, 37 tRNA, and 8 rRNA genes, and have GC contents of 37.9% and 37.8%, respectively. Phylogenetic analysis confirmed the maternal origin of M. indica 'Guiqi' and revealed the closest affinity between M. quadrifida and M. similis, indicating widespread hybridization and introgressions.
