a Light micrographs of two Bracteacoccaceae, B. bullatus (top) and B. minor (bottom). Inset shows the typical bulbous extensions of the cell wall in B. bullatus. b Circos plot of genome features for B. bullatus and B. minor genomes. a–j Concentric circles from outermost to innermost include: pseudochromosome, GC content, gene number, LTR number, Repeat number, Copia number, Gypsy number, SNP distribution, Indel distribution, and synteny regions in the genomes of B. bullatus and B. minor. c Maximum-likelihood phylogeny of Bracteacoccaceae and related algae based on the concatenated sequences of 589 single-copy genes. The bootstrap values of all branches were 100% (n = 500). Divergence time of two Bracteacoccus species is highlighted in bold. The red circle represents the time point chosen as calibrator. The proportion of expanded, contracted, gained, and lost gene families are shown in pie charts with different colors. d The Venn diagram shows the number of gene families shared and unique between B. bullatus and B. minor genomes. e A Venn diagram depicting the shared and unique gene families of the two Bracteacoccaceae in comparison with representatives from four other families of Sphaeropleales.
