Here, we systematically evaluate the combined effects of nitrogen, phosphorous, and potassium with different doses of each element, applied to either foliage or roots, on plant growth parameters and the mycorrhizal status of outplanted 3-year-old seedlings in five experimental Quercus ilex-T. melanosporum orchards. Fertilization did not significantly improve seedling aboveground growth, but the plants treated with the fertilizer 12-7-7 applied to the roots (HNr) displayed longer field-developed roots. Only the fertilizer with the highest dose of K (10-6-28) applied to the foliage (HKf) increased the probability of fine root tip colonization by T. melanosporum in field-developed roots. However, the plants treated with the same fertilizer applied to the soil (HKr) presented the highest probability for colonization by other competing mycorrhizal soil fungi. Potassium seems to have an important role in mycorrhizal development in these soils. Apart from T. melanosporum, we found 14 ectomycorrhizal morphotypes, from which seven were identified to species level, three to genus, two to family, and two remained unidentified by their morphological characteristics and DNA analyses.</style></abstract><accession-num><style face="normal" font="default" size="100%">20033737</style></accession-num></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Iotti, Mirco</style></author><author><style face="normal" font="default" size="100%">Lancellotti, Enrico</style></author><author><style face="normal" font="default" size="100%">Hall, Ian</style></author><author><style face="normal" font="default" size="100%">Zambonelli, Alessandra</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">The ectomycorrhizal community in natural Tuber borchii grounds</style></title><secondary-title><style face="normal" font="default" size="100%">FEMS MICROBIOLOGY ECOLOGY</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">bianchetto</style></keyword><keyword><style  face="normal" font="default" size="100%">ectomycorrhizal diversity</style></keyword><keyword><style  face="normal" font="default" size="100%">ITS-rDNA</style></keyword><keyword><style  face="normal" font="default" size="100%">mixed forest</style></keyword><keyword><style  face="normal" font="default" size="100%">morphotyping</style></keyword><keyword><style  face="normal" font="default" size="100%">truffiere</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2010</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2010///</style></date></pub-dates></dates><volume><style face="normal" font="default" size="100%">72</style></volume><pages><style face="normal" font="default" size="100%">250 - 260</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Although Tuber borchii is a commercially valuable truffle, its habitat has been virtually ignored. Here, we examine the ectomycorrhizal fungal communities in natural T. borchii grounds. Ectomycorrhizas under T. borchii ascomata and up to 1 m away were collected and morphologically assigned to pine or oak host plants. They were then morphotyped and molecular typed using internal transcribed spacer regions. Seventy ectomycorrhizal taxa were identified, many of which were rare. Tuber borchii dominated, forming 20% of ectomycorrhizas, with Thelephoraceae, Inocybaceae and Sebacinaceae being the other main species. Species composition was markedly affected by the host plant, although community structure and composition was also influenced by the location from which the soil cores were collected. Tuber dryophilum, an edible truffle, but without commercial value, shared the habitat with T. borchii. Its mycorrhizas were never found together with those of T. borchii. Tuber borchii was present on both oaks and pines, but was more abundant in soil cores where the roots of both hosts were present. It is suggested that the presence of young oaks contributed to the maintenance of T. borchii colonization on pines.</style></abstract><issue><style face="normal" font="default" size="100%">2</style></issue><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;pub-location: COMMERCE PLACE, 350 MAIN ST, MALDEN 02148, MA USA&lt;br/&gt;publisher: WILEY-BLACKWELL</style></notes></record></records></xml>
