How black truffles deal with the jumpers in their genome
Date:7/30/2014

y shed light on the relationships between DNA methylation and transposon-mediated genome shaping, intraspecific variability and commercially relevant organoleptic traits such as aroma and color"

Dr Matteo Pellegrini, from UCLA says: "This reversible methylation may increase the plasticity of the truffle genome, allowing it to adapt to its surroundings. Because the truffle lives underground and doesn't have an active spore dispersal system, it might need this plasticity to adapt to sudden environmental changes."

Dr Pao-Yang Chen, from UCLA says: "Instead of the methylated gene body or promoters that we usually see in plants and animals, the black truffle has very little gene body methylation and it appears that the methylation is occurring in the transposon. All this means the truffle has a very unique pattern of DNA methylation which may play a role in the gene regulation."
