Genome Biology and Evolution 11(4):1152–1165. doi:10.1093/gbe/evz061 https://doi.org/10.1093/gbe/evz061 (Open access) Repetitive satellite DNA (satDNA) sequences are abundant in eukaryote genomes, with a structural and functional role in centromeric function. We analysed the nucleotide…

Repetitive DNA in the edible button mushroom
I have a mental picture of the structure of a typical plant genome and typical animal genome, with their transposons (DNA and RNA), tandemly-repeated satellite sequences, minisatellites, microsatellites and other repeats. From this paper, I have a view of repeats in the second most important edible fungus (after yeast, Saccharomyces cerevisiae), the button mushroom Agaricus bisporus. Its genome, with n=13 chromosomes,…
