Abstract

Xylosma racemosa (Siebold & Zucc.) Miq. which plays an important role in ecology, medicine and economy, is a deciduous species of Salicaceae. In this paper, we sequenced, assembled, and annotated the chloroplast (cp) genome of X. racemosa (Siebold & Zucc.) Miq. by using the sequencing data from Illumina Novaseq platform. The complete cp genome of X. racemosa is 157,262 bp in length, containing a large single-copy (LSC) region of 84,289 bp, and a small single-copy (SSC) region of 17,817 bp. It contains 131 genes, including 8 rRNA genes, 37 tRNAs genes and 86 protein-coding genes. The GC content of X. racemosa cp genome is 36.74%. The phylogenetic analysis suggests that X. racemosa is a sister species to Xylosma congesta in Salicaceae.

摘要

Xylosma racemosa (Siebold & Zucc.) Miq。杨柳属落叶树种，在生态、医学和经济方面具有重要作用。在本文中，我们对X的叶绿体 (cp) 基因组进行了测序、组装和注释。总状花序(Siebold & Zucc.) Miq. 通过使用来自 Illumina Novaseq 平台的测序数据。的完整基因组的cp X.总状的长度是157262个碱基，含84289碱基对的大单拷贝（LSC）区域，和17817碱基对的小的单拷贝（SSC）区域。它包含131个基因，包括8个rRNA基因、37个tRNAs基因和86个蛋白质编码基因。X.racemosa cp基因组的GC含量为36.74%。系统发育分析表明X. racemosa是杨梅科木槿属的姊妹种。
