Centromere assembly and related annotations from Naish et. al (2021) are now available as new options in JBrowse. In the upper left hand corner of the JBrowse main window, click on ‘Genome’ to switch between the ColCEN genome and the Araport11 Genome to view the different chromosome assemblies. The supporting data files are available from the Genes section in our Downloads. Thank you to the Henderson research group for working with TAIR to make this data widely available
