Périgord truffles and its genetic secrets
The genome of the nose contains many "jumping genes" and repeated sequences. Epigenetic processes such as DNA methylation, could control the genes of this famous mushroom, so some characters as its aromas and color characteristics.

Especially prized by gourmets, black truffles, also known by their name Perigord truffles are second species most expensive. The fungi that produce them are from the species Tuber melanosporum . They grow on the roots of oak and hazel, with a symbiotic relationship that forms a ectomycorrhizae.
Its genome has 125 million base pairs (Mbp), that is to say, it is comparable to the size of Arabidopsis Arabidopsis thaliana , a plant commonly used in laboratories. It contains a particularly high or transposable "elements number gene jumping "that can move: it would have 6-20 times more than most fungi filamentous sequenced to date and 4 times more than Arabidopsis . Over 58% of the genome of the black truffle is composed of repetitions and jumping genes.
