Transposon mediated expansion of histone and folate-related functional genes in Glyptosternon maculatum genome

A: GO functional enrichment for expanded gene families in G. maculatum genome. B: Number of histones and their positional relationship with transposons in G. maculatum genome, compared with their counterparts in P. fulvidraco and I. punetaus. Color represents repetitive types. C: Distribution of insertion times for all LINE/L2 and those with histone genes. D: Expanded and naturally selected genes in folate metabolism. E: Expansion of mthfd1l gene in G. maculatum genome compared to P. fulvidraco and I. punetaus genomes. F: Synteny of repetitive elements around duplicated mthfd1l gene in G. maculatum genome. LINE RTE-BovB (red) and L2 (green) content is shown around genes.
