20.500.12556/RUL-137539 Original leaf colonisers shape fungal decomposer communities of Phragmites australis in intermittent habitats Common reed (Phragmites australis) has high biomass production and is primarily subjected to decomposition processes affected by multiple factors. To predict litter decomposition dynamics in intermittent lakes, it is critical to understand how communities of fungi, as the primary decomposers, form under different habitat conditions. This study reports the shotgun metagenomic sequencing of the initial fungal communities on common reed leaves decomposing under different environmental conditions. We demonstrate that a complex network of fungi forms already on the plant persists into the decomposition phase. Phragmites australis leaves contained at least five fungal phyla, with abundant Ascomycota (95.7%) and Basidiomycota (4.1%), identified as saprotrophs (48.6%), pathotrophs (22.5%), and symbiotrophs (12.6%). Most of the correlations between fungi in fresh and decomposing leaves were identified as co-occurrences (positive correlations). The geographic source of litter and leaf age did not affect the structure and diversity of fungal communities. Keystone taxa were mostly moisture-sensitive. Our results suggest that habitat has a strong effect on the formation of the fungal communities through keystone taxa. Nevertheless, it can also alter the proportions of individual fungal groups in the community through indirect effects on competition between the fungal taxa and their exploitation of favourable conditions. community networks fungal communities keystone species litter decomposition Phragmites australis water regime omrežja združb glivne združbe ključne vrste razgradnja opada vodni režim Phragmites australis true false true Angleški jezik Slovenski jezik Članek v reviji 2022-06-21 12:15:16 2022-06-21 12:15:17 2022-09-15 04:15:21 0000-00-00 00:00:00 2022 0 0 14 str. iss. 3, art. 284 Vol. 8 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 574 2309-608X 10.3390/jof8030284 101081859 jof-08-00284-v2.pdf jof-08-00284-v2.pdf 1 8D601F398E38FE41E31196C716907F62 cdaaf83e7ddc3ec2593d7f7a8a7def25c424f73ac31575f5c09c31954c611124 38d76fd4-f14b-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=157526 https://www.mdpi.com/2309-608X/8/3/284 0 dce85f4c-f14a-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=157525 Biotehniška fakulteta 0 0 0
