In this study, we have analysed the spatial genetic structure of\u00a0<em>Tuber melanosporum<\/em>\u00a0populations, a heterothallic ascomycete that produces edible fruit bodies.<\/li>\n<li style=\"text-align: justify;\">Ectomycorrhizas from oaks and hazels from two orchards were mapped and genotyped using simple sequence repeat markers and the mating type locus. The distribution of the two\u00a0<em>T.\u00a0melanosporum<\/em>\u00a0mating types was also monitored in the soil. In one orchard, the genetic profiles of the ascocarps were compared with those of the underlying mycorrhizas.<\/li>\n<li style=\"text-align: justify;\">A pronounced spatial genetic structure was found. The maximum genet sizes were 2.35 and 4.70\u00a0m in the two orchards, with most manifesting a size &lt;\u00a01\u00a0m. Few genets persisted throughout two seasons. A nonrandom distribution pattern of the\u00a0<em>T.\u00a0melanosporum<\/em>was observed, resulting in field patches colonized by genets that shared the same mating types.<\/li>\n<li style=\"text-align: justify;\">Our findings suggest that competition occurs between genets and provide basic information on\u00a0<em>T.\u00a0melanosporum<\/em>\u00a0propagation patterns that are relevant for the management of productive truffle orchards.<\/li>\n<\/ul>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Fine\u2010scale spatial genetic structure of the black truffle (Tuber melanosporum) investigated with neutral microsatellites and functional mating type genes C Murat, A Rubini, C Riccioni, H la Varga, E Akroume, B Belfiori, M Guaragno \u2026 New Phytologist Keywords: ectomycorrhizas; genets; &hellip; <a href=\"https:\/\/mycor.iam.inrae.fr\/IAM\/?p=832\">Continue reading <span class=\"meta-nav\">&rarr;<\/span><\/a><\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[2],"tags":[],"class_list":["post-832","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\/832","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=832"}],"version-history":[{"count":0,"href":"https:\/\/mycor.iam.inrae.fr\/IAM\/index.php?rest_route=\/wp\/v2\/posts\/832\/revisions"}],"wp:attachment":[{"href":"https:\/\/mycor.iam.inrae.fr\/IAM\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=832"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/mycor.iam.inrae.fr\/IAM\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=832"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/mycor.iam.inrae.fr\/IAM\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=832"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
