To better understand the links between EM fungi and saprotrophic fungi, we investigated the potential capacities of the EM fungus <i>Paxillus involutus<\/i> to mobilize nutrients from necromass of <i>Postia placenta<\/i>, a wood rot fungus, and to transfer these elements to its host tree. In this aim, we used pure cultures of <i>P. involutus<\/i> in the presence of labelled <i>Postia<\/i> necromass (<sup>15<\/sup>N\/<sup>13<\/sup>C) as nutrient source, and a monoxenic mycorrhized pine experiment also, composed of labelled <i>Postia<\/i>necromass and <i>P. involutus<\/i> culture in interaction with pine seedlings. The isotopic labelling was measured in both experiments. In pure culture, <i>P. involutus<\/i> was able to mobilize N, but C as well, from the <i>Postia<\/i> necromass. In the symbiotic interaction experiment, we measured high <sup>15<\/sup>N enrichments in all plant and fungal compartments. Interestingly, <sup>13<\/sup>C remains mainly in the mycelium and mycorrhizas, demonstrating that the EM fungus transferred essentially N from the necromass to the tree. These observations reveal that fungal organic matter could represent a significant N source for EM fungi and trees, but also a C source for mycorrhizal fungi, including in symbiotic lifestyle.<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>First evidences that the ectomycorrhizal fungus Paxillus involutus mobilizes nitrogen and carbon from saprotrophic fungus necromass\u00a0E Akroume, F Maillard, C Bach, C Hossann, C Brechet, N Angeli, B Zeller, &#8230;\u00a0Environmental microbiology Summary Fungal succession in rotting wood shows a surprising &hellip; <a href=\"https:\/\/mycor.iam.inrae.fr\/IAM\/?p=9273\">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-9273","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\/9273","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=9273"}],"version-history":[{"count":0,"href":"https:\/\/mycor.iam.inrae.fr\/IAM\/index.php?rest_route=\/wp\/v2\/posts\/9273\/revisions"}],"wp:attachment":[{"href":"https:\/\/mycor.iam.inrae.fr\/IAM\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=9273"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/mycor.iam.inrae.fr\/IAM\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=9273"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/mycor.iam.inrae.fr\/IAM\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=9273"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
