IntroductionForests in the Mediterranean basin are currently in decline. Their resilience has been eroded as a result of climate change and anthropogenic impacts, making them vulnerable to increasingly frequent episodes of drought, fire and the spread of pests and diseases. The impact of these natural and anthropogenic events on soil biodiversity is of particular concern, as the soil fungal community plays a key role in ecosystem homeostasis.Objectives and methodsIn order to analyse the relationship between soil health status and fungal diversity, soil samples were collected from declining Mediterranean forests of Castanea sativa (chestnut), Quercus ilex (holm oak), Quercus suber (cork oak) and Quercus pyrenaica (Pyrenean oak). A metabarcoding study was carried out by sequencing the ITS genomic region.ResultsA total of 674 fungal genera were found. It has not been possible to explain the differences in health status from the fungal genera found exclusively on declining forest soils, as none of them have been described as pathogenic. Healthy chestnut soils were characterized by a high alpha diversity and a higher abundance of the genus Metarhizium. No differentially abundant genera were found in any of the other forest species tested. Declining chestnut soils harbored more abundance of ectomycorrhizae and soil saprotrophs than healthy samples. Ectomycorrhizae were the dominant lifestyle in all oak species regardless of health status, whereas arbuscular mycorrhizae were preferentially found in declining cork oak soils.DiscussionThis work highlights the resilience of fungal communities of soil against decline and highlights the need to further investigate its relationship with the forest’s ability to cope with the challenges of climate change.

The mycotaxa belonging to Erysiphales reported from Nepal since 1966, are revised based on 20 published papers. The recent moleculer and phyllogenetic analysis have done several changes in the nomenclature of several powdery mildew species reported earlier from Nepal. Some were erroneously reported, while some species have undergone synonyms. Near about eighteen species of Oidium (anamorphic: imperfect stage) reported earlier still need collections, examination and study are not incorporated here. The present checklist provides corrections to misidentified species with their current (authentic) or valid names and some additons have been made based on publications. The list also records three endemic species. So, the revision includes 13 genera and 53 species parasitic on 76 flowering plants gathered from different areas of Nepalese Himalayan belt.

“…Pleurotus ostreatus is the predatory mushroom known to produce nematocidal toxin causing their immobilization and death [7][8][9] . There are several compounds produced by this fungus: trans-2-decenedioic nematocidal toxin that paralyze and kill nematodes, linoleic acid reduces nematodes' head size.…”

Soil phytopathogenic nematodes cause great damage to agricultural plants. Different methods have been used to control them. However, this issue still requires a more effective solution. Caenorhabditis elegans (CGC Strain wild type N2) was applied as a model with E. coli OP50 used as a feeding substrate for nematodes. Our approach was based on the thermodynamically substantiated creation of growth conditions unfavorable for nematodes to suppress them irreversibly. Nematodes control effect was also enhanced via the application of the strain Pleurotus ostreatus Po4. It is based on the study of the impact of key parameters such as pH, redox potential (Eh, mV), and O2 presence as well as P. ostreatus Po4 and bacteria (Escherichia coli OP50 and a native microbial community of compost of plant residues) on nematodes. As a result, the patterns of C. elegans N2 inhibition were studied. The creation of anaerobic conditions via the application of P. ostreatus Po4 and bacteria provided the irreversible suppression of nematodes. This research contributes to the development of the foundations to preserve agricultural plants, and increase crop yield as well as the approach for environmentally friendly control of phytopathogens.
