Abstract

Giant reed () is widely distributed across the globe and is considered an important energy crop. This study presents the first comprehensive analysis of the chloroplast genome of giant reed, revealing detailed characteristics of this species' chloroplast genome. The chloroplast genome has a total length of 137,153 bp, containing 84 protein-coding genes, 38 tRNA genes, and 8 rRNA genes, with a GC content of 39%. Functional analysis indicates that a total of 45 photosynthesis-related genes and 78 self-replication-related genes were identified, which may be closely associated with its adaptability and growth characteristics. Phylogenetic analysis confirmed that cv. Lvzhou No.1 belongs to the Arundionideae clade and occupies a distinct evolutionary position compared to other species. The findings of this study not only enhance our understanding of the giant reed genome but also provide valuable genetic resources for its application in biotechnology, bioenergy crop development, and ecological restoration.

摘要

芦竹（）广泛分布于世界各地，被认为是一种重要的能源作物。本研究首次对芦竹的叶绿体基因组进行了全面分析，揭示了该物种叶绿体基因组的详细特征。叶绿体基因组全长 137153bp，包含 84 个蛋白编码基因、38 个 tRNA 基因和 8 个 rRNA 基因，GC 含量为 39%。功能分析表明，共鉴定出 45 个与光合作用相关的基因和 78 个与自我复制相关的基因，这些基因可能与芦竹的适应性和生长特性密切相关。系统发育分析证实， cv. Lvzhou No.1 属于 Arundionideae 分支，与其他种相比占据独特的进化地位。本研究的结果不仅加深了我们对芦竹基因组的理解，还为其在生物技术、生物能源作物开发和生态恢复中的应用提供了有价值的遗传资源。
