a, A neighbour-joining phylogeny of CACTA families. Four major clades with high bootstrap support are marked in different colours. Format of sequence ID: āf number 1ānumber 2ā, where number 1 is the family ID and number 2 is the copy number of that family. For example, āf183 1639ā indicates that family 183 has 1,639 copies. The black clade is the outgroup. The branch length is not proportional to the genetic distance. b, Chromosome-wide distribution of the high-copy-number families (copy-numberāā„ā100) among the four major clades of CACTAs. The colour scheme is the same in a and b.
