Comparative karyograms of 14 Rhynchospora species based on the barcode oligo-probes Rbv-I (green) and Rbv-II (magenta). For each species, chromosome pairs are ordered from left to right according to their putative R. breviuscula orthologs. Insets illustrate chromosome fusions in R. pubera and R. tenuis, and an inversion in chr1 in R. riparia. Asterisk points to signal duplication in chr2 and chr5 of R. filiformis and R. riparia, respectively, likely due to chromosomal translocations. For species without clear oligo-probe patterns, chromosome pairs were arranged according to their decreasing sizes. CF indicates chromosome fusion events; Inv refers to inversions, LS refers to loss of signal (deletions), while SD refers to signal duplications. WGD denotes whole genome duplication. Clade numbering and phylogenetic relationships are based on Costa et al. (2023). Section assignments (grey bars on the right) are given based on recent phylogenetic and taxonomic revisions (Thomas et al., 2009; Buddenhagen, 2016; Silva Filho et al., 2021). Bar = 5 µm.
