Title: Amplification and adaptation of centromeric repeats in polyploid switchgrass species

Abstract

Centromeres in most higher eukaryotes are composed of long arrays of satellite repeats (Henikoff et al., 2001; Jiang et al., 2003). In addition, centromeres in the same plant or animal species are often dominated by a single satellite repeat family. For example, human centromeres are composed exclusively of the c. 171‐bp alpha satellite repeats (Willard & Waye, 1987; Miga et al., 2014). Similarly, each of the five centromeres of the model plant Arabidopsis thaliana (2n = 2x = 10) contains several megabases (Mb) of a 178‐bp satellite repeat (Maluszynska & Heslop‐Harrison, 1991; Murata et al., 1994; Jackson et al., 1998; Nagaki et al., 2003). Nucleosomes in centromeres are defined by the presence of cenH3 (CENP‐A in mammalian species), a centromere‐specific H3 variant. The satellite repeats in a single centromere often expand to several megabases and are associated with both cenH3 nucleosomes and pericentromeric H3 nucleosomes (Schueler et al., 2001; Jin et al., 2004; Shibata & Murata, 2004; Zhang et al., 2008). Nevertheless, such satellite repeats are intriguingly restricted to the centromeric regions and do not spread to interstitial or telomeric regions of the chromosomes.
