The mechanisms and the gene networks involved in this adaptation could be mainly due to extension\/contraction of gene families in particular those involved in stress response. Among these gene families, our preliminary data on the GSTome performed on the wood decaying fungus Phanerochaete chrysosporium revealed that duplications have been followed in all investigated cases (>15 isoforms) by neo-functionnalisation processes leading to different specificities\/activities in the various investigated enzymes. Furthermore, beside the classical genes involved in stress responses, we have highlighted the induction of genes coding for small secreted proteins (SSP) in response to oak extractives. These small proteins do not exhibit any homology with sequences available in the databases. A clear relationship has been observed between wood specificity and secretion of such proteins.<\/p>\n Besides these examples, comparative genomic analyses at inter and intra species level are underway to identify expanded new detoxification or signalling families involved in the adaptation to the degradation of various recalcitrant compounds.<\/p>\n <\/p>\n","protected":false},"excerpt":{"rendered":" Ma\u00eetre de Conf\u00e9rences Section CNU : 66 (english see below) Profil de publication: Physiologie\/Biologie cellulaire Vacant au 02\/09\/2014 Profil enseignement\u00a0: Fili\u00e8res de formation concern\u00e9es\u00a0: UFR STB- D\u00e9partement Biologie V\u00e9g\u00e9tale- G\u00e9n\u00e9tique et Microbiologie – Licence Sciences du Vivant, Master (For\u00eat, Agronomie, … Continue reading
