Inbreeding drives maize centromere evolution
WebAug 24, 2016 · Recent cenH3-binding experiments revealed that the maize centromere 5 of the B73 inbred has shifted from its ancestral location enriched in CentC satellite repeats (Schneider et al., 2016). We found that Helitrons are less abundant in CentC-rich regions and are interspersed with all types of CRM elements (Figure S3). WebThe diversity of centromere-specific DNA repeats in different species (centromere paradox) and the seemingly parallel rapid evolution of the cenH3 histone protein have previously …
