Forty new genomes shed light on sexual reproduction and the origin of tetraploidy in Microsporidia
Fig 4
Proportion of multi-copy genes which coalesce prior to genomes.
Heatmap showing the fraction of genes that support a more recent homeologue coalescence than between-species coalescence. Fractions greater than 50% are indicated in green, whereas fractions lower than 50% are indicated in purple. The phylogeny is an ASTRAL [75] phylogeny summarizing individual phylogenies of 600 BUSCO genes (microsporidia_odb10) [76] from all publicly available tetraploid assemblies and the tetraploid assemblies generated in this study. The branch lengths were estimated using a concatenated alignment of the individual BUSCOs used, with IQ-TREE [77]. The phylogeny is congruent with the phylogeny in Fig 2. The data underlying this figure can be found in S2 Text. The figure was generated using Matplotlib [92] and ToyTree [73], and manually annotated using InkScape (version 1.2.2).
