ecological significance of wood rotting fungi

[Ecological function of wood-inhabiting fungi in forest ecosystem].

forest ecosystem have symbiosis relationship with wood-decaying fungi. Wood-inhabiting fungi could offer the nutrition for many insects and birds, and spores of many wood-rotting species are spread by some insects. The high biodiversity of wood-decaying fungi is one of the important factors for the health of forest ecosystem.

Based on decay stages of wood, decay stage III harbored the highest number of wood-rotting fungi (32 species). The number of species occurring on the sapwood and on bark was equal (23 each) and 10 were common to both. The pH and percentage moisture content of the hosts ranged from 2.88 to 6.57 and 10 to 58, respectively.

A trait-based understanding of wood decomposition by fungi ...

Fungi play a key role in the global carbon cycle as the main decomposers of litter and wood. Although current climate models reflect limited functional variation in microbial groups, fungi differ vastly in their decomposing ability. Here, we examine which traits explain fungal-mediated wood decomposition. In a laboratory study of 34 fungal isolates, we found that decomposing ability varies ...

A Review of the Role of Fungi in Wood Decay of Forest ...

Fungi play a number of ecological roles in forest ecosystems that affect the health, diversity, productivity, and development of their biotic communities. Such roles include mycorrhizal associations with vascular plants, pathogens of commercial tree species, decomposers of coarse organic material, and food resources for wildlife. 2

Breaking down wood decomposition by fungi

Slow growing, stress-tolerant fungi with poor intrinsic wood decaying abilities are more likely to exist in drier forests with high precipitation seasonality. In contrast, fast-growing, highly...

A Review of the Role of Fungi in Wood Decay of Forest ...

Fungi most associated with wood 64 decay are the filamentous species of Basidiomycota and Ascomycota (Arnstadt et al. 2016, Swift 65 1982). 66 More casually, fungialso can include the fungus-like slime molds and water molds. 67 Although not discussed here, these nonetheless can be important ecologically and economically, 68 and are more often considered in forest management under pathogen and disease programs.

Evolutionary dynamics of host specialization in wood-decay fungi

The majority of wood decomposing fungi are mushroom-forming Agaricomycetes, which exhibit two main modes of plant cell wall decomposition: white rot, in which all plant cell wall components are degraded, including lignin, and brown rot, in which lignin is modified but not appreciably removed. Previous studies suggested that brown rot fungi tend to be specialists of gymnosperm hosts and that ...

Biocontrol of wood-rotting fungi - NISCAIR

It has been established that wood-rotting fungi, particularly basidiomycetes, damage forest wood even more than insects, marine animals or bacteria3. These basidiomycetes are categorized as either white- or brown-rot fungi. Brown-rot fungi (BRF) decompose primarily the carbohydrate component of the wood.

Identification of the specific genes and enzymes involved in the fungal degradation of lignocellulosic biomass derived from feedstocks with various compositions is essential to the development of improved bioenergy processes. In order to elucidate the effect of substrate composition on gene expression in wood-rotting fungi, we employed microarrays based on the annotated genomes of the brown ...

Fungal ecology - introduction

Fungi get their nutrients from existing organic matter and there are many sources of organic matter in the world - leaf litter, dung, soil, animals, dead wood and living plants - to name just a few. Fungi use them all.

THE ROLE OF WOOD DECAY FUNGI IN CONIFEROUS ...

In general, wood-rotting fungi can metabolize wood only if its moisture content is above approximately 25%. At 25 % water content and above, free water is available on the surface of the wood cell wall where it acts as a medium for two diffusion processes: that of fungal enzymes to wood s, and the products of

The most important organisms in the decomposition of wood are the white- and brown-rot fungi, whose activities result in a tremendous loss of resources in, for example, the timber industry. White-rot fungi degrade all components of lignocellulose, while brown-rot fungi mineralize polysaccharides but are unable to de ize lignin [ 1 ].

Ecological and functional effects of fungal endophytes on ...

However, the ecological relevance of those results remains unclear, as microcosm settings strongly limit the diversity of fungi colonizing wood. We also predicted that the niche pre‐emption caused by the presence of endophytes would have a stronger effect on community taxonomic composition than functioning, but that this effect would attenuate through time (Fukami, 2015 ).
