Abstract
The complete chloroplast (cp) genome sequence of Eustrephus latifolius was firstly determined in subfamily Lomandriodeae of family Asparagaceae. It was 159,736 bp and contained a large single copy region (82,403 bp) and a small single copy region (13,607 bp) which were separated by two inverted repeat regions (31,863 bp). In total, 132 genes were identified and they were consisted of 83 coding genes, 8 rRNA genes, 38 tRNA genes, 3 pseudogenes. rpl23 and clpP were pseudogenes due to sequence deletions. Among 23 genes containing introns, rps12 and ycf3 contained two introns and the rest had just one intron. The intact ycf68 was identified within an intron of trnI-GAU. The amino acid sequence was almost identical with Phoenix dactylifera in Aracales. Ycf1 of E. latifolius was completely located in IR. It was similar to cp genome structure of Lemna minor, Spirodela polyrhiza, Wolffiella lingulata, Wolffia australiana in Alismatales.
