Table 2 Size distribution of AT-rich blocks in different well-sequenced fungal genomes

From: Trichoderma reesei complete genome sequence, repeat-induced point mutation, and partitioning of CAZyme gene clusters

  1. aThe interspersed AT-rich blocks were identified by having AT contents ≥6% higher than that of average DNA in each fungal genome
  2. bIn Saccharomyces cerevisiae, AT-rich blocks (almost all ≤3 kb) are known to be well correlated with the intergenic regions that bind to the sister chromatin cohesion complexes. There are no or only a few longer AT-rich blocks (≥3 kb) in the genomes of Saccharomyces cerevisiae, Schizosaccharomyces pombe, Candida glabrata, Ustilago maydis, Cryptococcus neoformans, and Coprinopsis cinerea
