Emerging function for a glutathione transferase in response to wood extractives toxicity
2014 - IRG/WP 14-10824
The first steps of wood degradation by fungi lead to the release of toxic compounds known as extractives. To better understand how lignolytic fungi cope with these products, a transcriptomic analysis of Phanerochaete chrysosporium genes was performed in presence of oak acetonic extractives. The most up-regulated genes relate to nutrition, nucleic acid modification, gene regulation, signalling and ...

Glutathione transferases and wood extracts
2015 - IRG/WP 15-10845
Wood rotting fungi have developed an efficient detoxification system allowing them to be well adapted to their way of life, these fungi generating and encountering potential toxic compounds during wood degradation. Belonging to this detoxification network, glutathione transferases are particularly extended in these fungi and their presence could reflect the chemical environments encountered by the...

Exudate production: a detoxification strategy of wood decaying fungi
2016 - IRG/WP 16-10868
Even often observed, the exudate production in fungi remains mainly unstudied. During growth on oak wood, the white-rot fungus Trametes versicolor produces droplets of a red-brown liquid, this phenomenom being observed with nine studied strains. One of these strains secretes a similar exudate on rich medium even in the absence of wood. This secretion seems to be linked to the formation of special...
