However, some of these enzymes are conserved among fungi with dissimilar lifestyles. We identified genes from Glycoside Hydrolase family GH131 as commonly expressed during plant\u2010tissue colonisation by saprobic, pathogenic, and symbiotic fungi. By searching all the publicly available genomes, we found that GH131\u2010coding genes were widely distributed in the Dikarya subkingdom, except in Taphrinomycotina and Saccharomycotina, and in phytopathogenic Oomycetes, but no other eukaryotes nor prokaryotes. The presence of GH131 in a species was correlated with its association with plants as symbiont, pathogen, or saprobe. We propose that GH131\u2010family expansions and horizontal\u2010gene transfers contributed to this adaptation. We analysed the biochemical activities of GH131 enzymes whose genes were up\u2010regulated during plant\u2010tissue colonisation in a saprobe (<i>Pycnoporus sanguineus<\/i>), a plant symbiont (<i>Laccaria bicolor<\/i>), and three hemibiotrophic\u2010plant pathogens (<i>Colletotrichum higginsianum<\/i>, <i>C. graminicola<\/i>, <i>Zymoseptoria tritici<\/i>). These enzymes were all active on substrates with \u03b2\u20101,4, \u03b2\u20101,3, and mixed \u03b2\u20101,4\/1,3 glucosidic linkages. Combined with a cellobiohydrolase, GH131 enzymes enhanced cellulose degradation. We propose that secreted GH131 enzymes unlock the PCW barrier and allow further deconstruction by other enzymes during plant tissue colonisation by symbionts, pathogens and saprobes.<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Broad\u2010specificity GH131 \u03b2\u2010glucanases are a hallmark of Fungi and Oomycetes that colonise plants\u00a0GE Anasontzis, MH Lebrun, M Haon, C Champion, A Kohler, N Lenfant, &#8230; Environmental Microbiology Summary Plant\u2010tissue\u2010colonising fungi fine\u2010tune the deconstruction of plant\u2010cell walls (PCW) using different sets &hellip; <a href=\"https:\/\/mycor.iam.inrae.fr\/IAM\/?p=9567\">Continue reading <span class=\"meta-nav\">&rarr;<\/span><\/a><\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[2],"tags":[],"class_list":["post-9567","post","type-post","status-publish","format-standard","hentry","category-academic-productions"],"_links":{"self":[{"href":"https:\/\/mycor.iam.inrae.fr\/IAM\/index.php?rest_route=\/wp\/v2\/posts\/9567","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/mycor.iam.inrae.fr\/IAM\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/mycor.iam.inrae.fr\/IAM\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/mycor.iam.inrae.fr\/IAM\/index.php?rest_route=\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/mycor.iam.inrae.fr\/IAM\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=9567"}],"version-history":[{"count":0,"href":"https:\/\/mycor.iam.inrae.fr\/IAM\/index.php?rest_route=\/wp\/v2\/posts\/9567\/revisions"}],"wp:attachment":[{"href":"https:\/\/mycor.iam.inrae.fr\/IAM\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=9567"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/mycor.iam.inrae.fr\/IAM\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=9567"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/mycor.iam.inrae.fr\/IAM\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=9567"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
