Fig. 2

The identified polycistronic transcriptional units (PTUs) in the C. lentillifera chloroplast. The protein-coding genes, ORFs, rRNA and tRNA genes are indicated in pink, yellow, green or blue, respectively; atpA and ORF12 are shown in gray because the Iso-seq reads did not cover the entire gene. Genes in the dotted boxes are related to the conserved gene clusters across all Bryopsidales identified by Cremen et al. [13]. The gene order, including intronic ORFs within each PTU, is based on the physical genome location
