Figure 3From: Building a model: developing genomic resources for common milkweed (Asclepias syriaca) with low coverage genome sequencingThe rDNA cistron of Asclepias syriaca. Blue boxes represent genes. Thick black lines represent additional transcribed sequence. The gray and dashed lines represent non-transcribed and unassembled sequence respectively. Only partial sequences of the non-transcribed spacer (NTS) and external transcribed spacer (ETS) were able to be assembled due to repeats, so the length of the intergenic spacer (IGS) remains unknown.Back to article page
