Abstract:
... We studied the endolichenic fungal communities from saxicolous lichens occupying the cobbles at Nahal Boker, the central Negev Desert, Israel. Overall, 101 species belonging to 64 genera were isolated from 12 lichen species collected in three seasons from the south-facing slope (SFS) and north-facing slope (NFS) of the wadi. The endolichenic communities possessed a set of traits, which helped them ...

Abstract:
... Fungal endophyte community amplicon sequencing can lose a significant number of informative reads due to host-plant co-amplification. Blocking of plant-specific sequences with peptide nucleic acid (PNA) clamps has been shown to improve metrics of detected microbial diversity in studies targeting 16S and 18S regions of rRNA genes. However, PNA clamping has not been applied to the plant ITS region o ...

However, very few studies have investigated the microbial composition of biofilms on newly developed wooden vats and how communities assemble and evolve. In the present study, the microbial communities of biofilms were characterized ...

Abstract:
... In forest ecosystems, fungi are the key actors in wood decay. They have the capability to degrade lignified substrates and the woody biomass of coniferous forests, with brown rot fungi being common colonizers. Brown rots are typically involved in the earliest phase of lignocellulose breakdown, which therefore influences colonization by other microorganisms. However, few studies have focused on the ...
