Abstract
\n<\/span>Esca is one of the most devastating of the grapevine trunk diseases, that affect vineyards around the world.
\nOne of its main symptoms is white rot, also called <\/span>amadou<\/span>. In white rot, <\/span>Fomitiporia mediterranea <\/span><\/em>(M.
\nFischer) is the major species identified in Europe. White-rot fungi have evolved with their substrates and
\nmay have developed specifically adapted degradation and detoxification mechanisms.
\nThe main objective of this thesis is to understand how <\/span>F. mediterranea <\/span><\/em>is adapted to its substrate, grapevine
\nwood. The behavior of <\/span>F. mediterranea <\/span><\/em>during wood degradation on different wood species was monitored.
\nCarbon mineralization rate, wood mass loss, chemical composition in structural compounds and extractives,
\nfungal biomass production and protein secretion (secretome) upon cultures on sawdust were measured. In
\na second step, the colonization of <\/span>F. mediterranea <\/span><\/em>on wood blocks was followed. In addition to the
\nphysiological approach, a non-targeted metabolomic approach, with molecular networking, was used to
\ndescribe fungal and wood metabolomes during colonization.
\n<\/span>F. mediterranea<\/em> <\/span>is able to degrade several wood species, including grapevine cv. \u2018Gewurztraminer\u2019 and
\n\u2018Riesling\u2019, beech and oak, in sawdust or blocks, using a simultaneous degradation pattern. Parallely, the
\nfungus regulates its secretome in relation with its substrate: a larger number of oxidoreductases were
\nsecreted on grapevine sawdust. This could be correlated with the observed degradation of grapevine lignin
\nand specialized metabolites, mainly stilbenes. Other factors than the structural and chemical composition
\nof the substrate, which could be involved in the adaptation of <\/span>F. mediterranea<\/span><\/em>,<\/em> are discussed.
\nThis work contributes to a better knowledge of the physiology of <\/span>F. mediterranea<\/span><\/em>,<\/em> one of the key fungal
\nspecies in Esca complexe disease<\/span><\/p>\n
