Water hyacinth ( Mart.) is a monocotyledonous aquatic plant renowned for its rapid growth, extensive proliferation, biological invasiveness, and ecological resilience to variations in pH, nutrients, and temperature. The International Union for Conservation of Nature (IUCN) has listed among the top 100 invasive species. However, comprehensive genomic information, particularly concerning its mitochondrial genome (mitogenome), remains surprisingly limited. In this study, the complete mitogenome of was analyzed using bioinformatics approaches. The mitogenome is 399,263 bp long and contains 38 protein-coding genes (PCGs), 24 tRNA genes, and 3 rRNA genes. Sequence analysis revealed that the complete mitogenome of the species contains 3,289 dispersed repeats, and 765 RNA editing sites in protein-coding genes. The mitogenome possessed un-conserved structures, including extensive sequence transfer between its chloroplasts and mitochondria. Our study on the mitogenome of offers critical insights into its evolutionary patterns and phylogenetic relationships with related taxa. This research enhances our understanding of this invasive species, known for its significant biomass and rapid overgrowth in aquatic environments.
凤眼蓝(凤眼蓝属)是一种单子叶水生植物,以其生长迅速、大量繁殖、生物入侵性以及对pH值、养分和温度变化的生态适应能力而闻名。国际自然保护联盟(IUCN)已将其列为100种最具入侵性的物种之一。然而,全面的基因组信息,尤其是关于其线粒体基因组(有丝分裂基因组)的信息,仍然极其有限。在本研究中,我们使用生物信息学方法分析了凤眼蓝的完整线粒体基因组。该线粒体基因组长度为399,263 bp,包含38个蛋白质编码基因(PCGs)、24个tRNA基因和3个rRNA基因。序列分析表明,该物种的完整线粒体基因组包含3289个分散重复序列,以及蛋白质编码基因中的765个RNA编辑位点。凤眼蓝的线粒体基因组具有不保守的结构,包括叶绿体和线粒体之间广泛的序列转移。我们对凤眼蓝线粒体基因组的研究为其进化模式以及与相关分类群的系统发育关系提供了关键见解。这项研究加深了我们对这种以在水生环境中显著的生物量和快速过度生长而闻名的入侵物种的理解。
