The complete chloroplast sequence of the Chikusichloa aquatica was determined in this study. The genome consists of 136 563 bp containing a pair of inverted repeats (IRs) of 20 837 bp, which was separated by a large single-copy region and a small single-copy region of 82 315 bp and 33 411 bp, respectively. The C. aquatica cp genome encodes 111 functional genes (71 protein-coding genes, four rRNA genes, and 36 tRNA genes): 92 are unique, while 19 are duplicated in the IR regions. The genic regions account for 58.9% of whole cp genome, and the GC content of the plastome is 39.0%. A phylogenomic analysis showed that C. aquatica is closely related to Rhynchoryza subulata that belongs to the tribe Oryzeae.
本研究测定了水生千金子的完整叶绿体序列。该基因组由136563bp组成，包含一对20837bp的反向重复序列（IRs），它们被一个82315bp的大单拷贝区域和一个33411bp的小单拷贝区域隔开。水生千金子叶绿体基因组编码111个功能基因（71个蛋白质编码基因、4个rRNA基因和36个tRNA基因）：92个是独特的，而19个在IR区域重复。基因区域占整个叶绿体基因组的58.9%，质体基因组的GC含量为39.0%。系统发育基因组分析表明，水生千金子与稻族的尖颖落芒草关系密切。
