A special case in point is that of fungi with a subterranean, light-shielded habitat such as\u00a0<em>Tuber spp<\/em>. Using as reference the genome sequence of the black truffle\u00a0<em>Tuber melanosporum<\/em>, we employed sequence prediction tools and expression data to gain insight on the photoreceptor systems expressed by this hypogeous ectomycorryzal fungus. These include a chromophore-less opsin preferentially expressed in fruiting bodies, a putative red light-sensing phytochrome that is not expressed at detectable levels in any of the examined developmental conditions, and a nearly canonical two-component (WC-1\/WC-2) photoreceptor system similar to the\u00a0<em>Neurospora<\/em>\u00a0white collar complex. The latter is expressed at relatively high levels throughout the different developmental stages of\u00a0<em>T. melanosporum<\/em>, except for sexual stage fruiting bodies where it is down-regulated. Various evidences, including the growth arrest phenotype elicited by blue light and the ability of a chimeric\u00a0<em>Tuber\/Neurospora<\/em>\u00a0WC-1 protein to complement a\u00a0<em>N. crassa wc-1<\/em><sup><em>ko<\/em><\/sup>blind strain suggest that the\u00a0<em>Tuber<\/em>\u00a0white collar complex is likely functional and capable of responding to blue-light. The other putative photoreceptor components we have identified in the\u00a0<em>T. melanosporum<\/em>\u00a0genome, especially the chromophore-less opsin and the likely non-functional phytochrome, may represent the signatures of adaptation to a hypogeous (light-shielded) lifestyle.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Photoreceptors in the dark: a functional white collar-like complex and other putative light-sensing components encoded by the genome of the subterranean fungus Tuber melanosporumR Gerace, B Montanini, M Proietto, E Levati, C De Luca, A Brenna, &#8230;\u00a0Fungal Biology Abstract Light &hellip; <a href=\"https:\/\/mycor.iam.inrae.fr\/IAM\/?p=7798\">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-7798","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\/7798","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=7798"}],"version-history":[{"count":0,"href":"https:\/\/mycor.iam.inrae.fr\/IAM\/index.php?rest_route=\/wp\/v2\/posts\/7798\/revisions"}],"wp:attachment":[{"href":"https:\/\/mycor.iam.inrae.fr\/IAM\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=7798"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/mycor.iam.inrae.fr\/IAM\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=7798"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/mycor.iam.inrae.fr\/IAM\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=7798"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
