Trees cope with drought through avoidance mechanisms or tolerance. Drought can result in changes in colonization by ectomycorrhizal fungi and in the structure of ectomycorrhizal communities. Survival of tree seedlings is supported through common mycelium networks. In moderate drought, there is greater colonization by ectomycorrhizal fungi compared to severe drought, resulting in several beneficial effects to the tree. Under drought, the frequency of ectomycorrhizal fungus Cenococcum geophilum Fr. often increases. C. geophilum sustains tree fine roots function and therefore roots are able to absorb water as soon as the drought period is over. Under drought, synthesis of recalcitrant organic compounds in roots, e.g. lignine, is increased. Recalcitrant compounds such as melanine are also found in C. geophilum, contributing to the accumulation of recalcitrant soil organic matter</dc:description><dc:description xml:lang="sl">Sušni stres sproži tako pri drobnih koreninah dreves kot pri ektomikoriznih glivah številne spremembe na različnih nivojih. Drevesa se branijo pred sušo z mehanizmi izogibanja in tolerance. Suša lahko vpliva na kolonizacijo z ektomikoriznimi glivami in na strukturo ektomikorizne združbe. Pomembno vlogo pri preživetju mladja ob suši imajo skupne micelijske mreže. Ob zmerni suši je kolonizacija z ektomikoriznimi glivami večja kot ob ekstremni suši, kar ima za drevo številne pozitivne učinke. V sušnih razmerah se pogosto še posebej poveča pogostnost ektomikorizne vrste Cenococcum geophilum Fr., ki omogoča, da drobne korenine ostanejo funkcionalne in takoj po končanem sušnem obdobju pričnejo z absorpcijo vode. V sušnih razmerah se poveča tvorba težko razgradljivih molekul v koreninah (lignin), prav tako pa se težko razgradljive molekule (melanin) tvorijo tudi pri ektomikorizni vrsti C. geophilum, kar prispeva h kopičenju težko razgradljivih organskih snovi v tleh</dc:description><edm:type>TEXT</edm:type><dc:type xml:lang="sl">znanstveno časopisje</dc:type><dc:type xml:lang="en">journals</dc:type><dc:type rdf:resource="http://www.wikidata.org/entity/Q361785" /></edm:ProvidedCHO><ore:Aggregation rdf:about="http://www.dlib.si/?URN=URN:NBN:SI:DOC-A6B4HSEA"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:DOC-A6B4HSEA" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:DOC-A6B4HSEA/fbeb8d9b-1613-4536-ba09-bcfd85a635fa/PDF" /><edm:rights rdf:resource="http://rightsstatements.org/vocab/InC/1.0/" /><edm:provider>Slovenian National E-content Aggregator</edm:provider><edm:intermediateProvider xml:lang="en">National and University Library of Slovenia</edm:intermediateProvider><edm:dataProvider xml:lang="sl">Gozdarski inštitut Slovenije</edm:dataProvider><edm:object rdf:resource="http://www.dlib.si/streamdb/URN:NBN:SI:DOC-A6B4HSEA/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:DOC-A6B4HSEA" /></ore:Aggregation></rdf:RDF>
