Centromere protein evolution and chromosome count variation in Drosera (Droseraceae), a group with holocentromeres.

Over the past century, many scholars have carried out cytological studies in Drosera resulting in over 600 chromosome counts for 125 species. These studies have observed high chromosome count variation both within and among species and hypothesized the presence of holocentromeres being associated with the high level of variation. We cleaned and reanalyzed previous chromosome count data and examined their evolutionary pattern across the phylogeny. In addition, we carried out phylotranscriptomic analysis using 18 transcriptomes in Drosera to examine patterns of centromere protein evolution.
