In this study, we determined the complete chloroplast genome of (Cycadaceae, ) using the Illumina sequencing data. The genome is 162,083 bp in length, including a pair of inverted repeats (IRs) of 25,003 bp each, which are separated by a large single-copy region (LSC) and a small single-copy region (SSC) with the size of 88,970 and 23,108 bp, respectively. The genome comprises 131 encoded genes in total, including 86 protein-coding genes (82 PCG species), 8 ribosomal RNA genes (4 rRNA species), and 37 transfer RNA genes (30 tRNA species). The overall GC content of the chloroplast genome is 39.42%, while the LSC, SSC, and IRs occupy 38.70, 42.03 and 36.52%, respectively. Based on complete chloroplast genome sequences from 13 species, we reconstructed the phylogenetic relationship of the 13 species and found that is closely related to .
在本研究中,我们利用Illumina测序数据测定了(苏铁科,)的完整叶绿体基因组。该基因组长度为162,083 bp,包括一对各长25,003 bp的反向重复序列(IRs),它们被大小分别为88,970 bp和23,108 bp的大单拷贝区域(LSC)和小单拷贝区域(SSC)隔开。该基因组总共包含131个编码基因,包括86个蛋白质编码基因(82种PCG)、8个核糖体RNA基因(4种rRNA)和37个转运RNA基因(30种tRNA)。叶绿体基因组的总体GC含量为39.42%,而LSC、SSC和IRs分别占38.70%、42.03%和36.52%。基于13个物种的完整叶绿体基因组序列,我们重建了这13个物种的系统发育关系,发现与密切相关。
