四射银杏是世界许多地区的一种入侵杂草，对当地生物多样性和农业造成严重破坏。在本研究中，其完整的叶绿体基因组是根据灯盏花全基因组测序数据组装而成的。环状基因组全长151,917个碱基，由一对反向重复序列(IRS，每个25,041个碱基)、一个大的单复制区(LSC，83,620个碱基)和一个小的单复制区(SSC，18,215个碱基)组成。该基因共编码111种基因(80种蛋白质、27种tRNA和4种rRNA)，其中21种为双拷贝。在10个PCG和6个tRNA物种中检测到内含子。核苷酸组成不对称(A占31.07%，C占18.58%，G占19.08%，T占31.27%)，A、 + 、T的总含量为62.34%。
Galinsoga quadriradiata is an invasive weed in many parts of the world, and are causing serious damages to local biodiversity and agriculture. In this study, its complete chloroplast genome was assembled from the whole-genome Illumina sequencing data. The circular genome is 151,917 bp long, and comprises a pair of inverted repeat regions (IRs, 25,041 bp each), a large single-copy region (LSC, 83,620 bp) and a small single-copy region (SSC, 18,215 bp). It encodes a total of 111 gene species (80 protein-coding, 27 tRNA and four rRNA species), with 21 of them occurring in double copies. Introns were detected in ten PCG and six tRNA species. The nucleotide composition is asymmetric (31.07% A, 18.58% C, 19.08% G & 31.27% T) with an overall A + T content of 62.34%.
