Genome sequencing was performed using HiSeqX at Macrogen Inc., Korea, from the extracted DNA of the six C. album. De novo assembly with confirmation was accomplished with Velvet v1.2.10 [40 (link)] after filtering raw reads using Trimmomatic v0.33 [41 (link)]. After obtaining the first draft of the chloroplast genome sequences, gaps were filled with GapCloser v1.12 [42 (link)], and all bases from the assembled sequences were confirmed by checking each base in the alignment (tview mode in SAMtools v1.9 [43 (link)]) against the assembled chloroplast genome generated with BWA v0.7.17 [44 ]. All these processes were conducted under the environment of the Genome Information System (GeIS; http://geis.infoboss.co.kr/; Park et al., in preparation) like other Amaranthaceae chloroplast genomes assembled [38 (link), 39 (link), 45 (link)–49 (link)].
