Fig. 2

Cladosporium fulvum has a low number of accessory genes. A Upset plot showing the number of hierarchical orthogroups (HOGs) containing genes from one or more isolates. The figure shows that almost all HOGs are shared by all isolates. B Scatterplot showing the estimated sizes of pan- and core genome of C. fulvum. The five genomes were sampled in all possible combinations of size x, with 1 ≤  ×  ≤ 5. Points represent the number of all HOGs (pangenome) and HOGs containing genes from all sampled genomes (core genome). The curves were fitted by linear regressions of the log-transformed median values of the pan- and core genome. The figure shows that the pangenome size grows slowly as more genomes are included, suggesting that the five sequenced genomes already capture most of the gene space in C. fulvum
