Genome size and chromosome structure of Cw. a Distribution plot of k-mer analysis using 17-mers. b Cw chromosome spread stained with DAPI and 5S nrDNA and 45S nrDNA probes. The 5S and 45S nrDNA are represented as green and red signals, respectively. Bar, 10 μm. (Waminal et al.) Eleven chromosome pairs displayed by size and shape. Chromosomes are arbitrarily lined up by size; bar, 10 μm. (Waminal et al.) Relative positions of 45S and 5S nrDNA blocks on chromosome 1. e Schematic diagram of the 45S and 5S transcription units clustered separately. Green boxes represent 5S nrDNA, and red boxes represent 45S nrDNA arrays. The number of copies presumed to be in one cell (Table S2) is listed above. f Sequence information for 5S and 45S nrDNA units. Green rectangles represent 5S; blue triangles indicate interspecific SNPs and InDels (Table S5). Red rectangles represent 18S, 5.8S, and 26S nrRNA, blue triangles indicate interspecific variations between Cw and Ca, and red triangles indicate three interspecific variations that coincide with intraspecific variations found in Cw (Table S5)
