High-Throughput Genomic Simple Sequence Repeat (SSR) Marker Development and Construction of a High Resolution Physical Map in Button Mushroom (Agaricus bisporus) Genome

Button mushroom [Agaricus bisporus (J.E. Lange) Imbach], is both a model organism and a worldwide cultivated edible mushroom species. Despite its scientific and economic relevance, efforts to develop molecular markers in A. bisporus genome are scarce and relatively recent. The present research reports the development of 3943 novel simple sequence repeat (SSR) markers specific to the A. bisporus genome. The marker set is well-distributed among the 13 A. bisporus chromosomes, saturating the entire genome with sequence-specific markers. The large number of novel, A. bisporus specific DNA markers introduced in the present work constitute a valuable resource for molecular genetic research in button mushroom, including strain identification and protection, and gene/QTL (Quantitative Trait Locus) mapping
