CIRCOS visualization of Iso-Seq data at the genome-wide level. a Karyotype of red clover chromosomes. b Comparison of APA sites mapped to red clover reference genome. c Novel transcript density from Iso-Seq data. The closer to red, the higher density the color represents and the closer to blue, the lower density the color represents. d Novel gene density from Iso-Seq data. e LncRNA density. The closer to the center, the lower density the dot represents. f Linkage of fusion transcripts. Purple, intra-chromosomal; Yellow, inter-chromosomal
