The whole chloroplast genome of wild rice (Oryza australiensis) is characterized in this study. The genome size is 135,224 bp, exhibiting a typical circular structure including a pair of 25,776 bp inverted repeats (IRa,b) separated by a large single-copy region (LSC) of 82,212 bp and a small single-copy region (SSC) of 12,470 bp. The overall GC content of the genome is 38.95%. 110 unique genes were annotated, including 76 protein-coding genes, 4 ribosomal RNA genes, and 30t RNA genes. Among these, 18 are duplicated in the inverted repeat regions, 13 genes contain one intron, and 2 genes (rps12 and ycf3) have two introns.
本研究对野生稻（澳洲野生稻）的完整叶绿体基因组进行了特征分析。基因组大小为135,224 bp，呈现典型的环状结构，包括一对25,776 bp的反向重复序列（IRa、b），它们被一个82,212 bp的大单拷贝区域（LSC）和一个12,470 bp的小单拷贝区域（SSC）隔开。基因组的总体GC含量为38.95%。共注释了110个独特基因，包括76个蛋白质编码基因、4个核糖体RNA基因和30个tRNA基因。其中，18个基因在反向重复区域中重复，13个基因含有一个内含子，2个基因（rps12和ycf3）有两个内含子。
