“…One of these showed high homology to mannose-6-phosphate isomerase, a protein involved in mannose synthesis and a known pathogenicity factor in Cryptococcus neoformans [ 41 ]. Several genes were found with a potential link to degradation of plant material, for example, those encoding L-threo-3-deoxy-hexulosonate aldolase, an enzyme involved in catabolism of D-galacturonate, a principal component of pectin [ 42 ], and catechol dioxygenase and 3-carboxy-cis,cis-muconate cyclase, both involved in metabolism of low-molecular weight aromatic compounds, such as protocatechuate and catechol, degradation products of lignin [ 43 - 46 ]. Also in this class, succinate-semialdehyde dehydrogenase [NADP + ], an enzyme involved in the GABA-shunt and found to be up-regulated in F. graminearum when grown on hop cell wall [ 47 ], was identified as a potential pathogenicity factor.…”

Background: Fusarium oxysporum f. sp. lycopersici is the causal agent of vascular wilt disease in tomato. In order to gain more insight into the molecular processes in F. oxysporum necessary for pathogenesis and to uncover the genes involved, we used Agrobacterium-mediated insertional mutagenesis to generate 10,290 transformants and screened the transformants for loss or reduction of pathogenicity.

“…Magnaporthales' such as Pyricularia penniseti were the converters of isoamylalcohol into isovaleraldehyde while other Magnaporthales' species converted fumaryl-acetoacetate into fumarate and acetoacetate [178,179]. Other roles played by the Sordariomycete's species were aromatic compounds metabolism, in which, phenolics and aryl alcohols/aldehydes were converted into acetate, formate and ethanol [180,181]. Similarity the Sordariomycete's community's abundances were also affected by the substrates and theenvironmental conditions ( Table 1 and 2).…”

The obstacle to optimal utilization of biogas technology is poor understanding of biogas' microbiome diversities over a wide geographical coverage. We performed random shotgun sequencing on twelve environmental samples. Randomized complete block design was utilized to assign the twelve treatments to four blocks, within eastern and central regions of Kenya. We obtained 42 million paired-end reads that were annotated against sixteen reference databases using two ENVO ontologies, prior to β-diversities studies. We identified 37 phyla, 65 classes and 132 orders. Bacteria richness dominated and composed 28 phyla, 42 classes and 92 orders, conveying substrate's versatility in the treatments. Though, fungi and Archaea composed 5 phyla, the fungi were richer; suggesting importance of hydrolysis and fermentation in biogas production. High β-diversity within the taxa was largely linked to communities' metabolic capabilities. Synergistales to mention but few, also catabolized macromolecules into smaller substrates to conserve energy. Furthermore, δ-Proteobacteria, Gloeobacteria and Clostridia affiliates syntrophically regulated PH2 and reduced metal to provide reducing equivalents. Methanomicrobiales and other Methanomicrobia species were the most prevalence Archaea, converting formate, CO2(g), acetate and methylated substrates into CH4(g). Thermococci, Thermoplasmata and Thermoprotei were among the sulfur and other metal reducing Archaea that contributed to redox balancing and other metabolism within treatments. Eukaryotes, mainly fungi were the least abundant guild, conveying largely Ascomycota and Basidiomycota species. Chytridiomycetes, Blastocladiomycetes and Mortierellomycetes were among the rare species, suggesting their metabolic and substrates limitations. Generally, we observed that environmental and treatment perturbations influenced communities' abundance, β-diversity and reactor performance largely through stochastic effect. Understanding diversity of biogas' microbiomes over wide environmental conditions and its productivity provides insights into better management and other effective strategies that ameliorate existing biochemical issues.

“…Its occurrence in this habitat could have resulted from its saprotrophic, pathogenic or antagonistic properties, contributing to the multifaceted community structure. As a saprotroph, C. hoffmannii has been categorized as a soft-rot fungus capable of decaying wood (Bugos, Sutherland, & Adler, 1988). Its pathogenicity towards woody hosts was observed by Damm et al (2010).…”

Abundance and diversity of fungi in naturally formed knots of Pinus sylvestris affected by Porodaedalea pini were investigated. Samples were taken from trees that were (i) affected, with internal heartwood decay and no conks, (ii) affected, with internal heartwood decay and conks and (iii) controls. The Illumina sequencing technology was used for amplification of DNA, sequencing and analysis. In total, 566,279 raw sequences were obtained from six samples. Sequences included 74% of culturable and 8.4% of non‐culturable fungi and 17.6% of organisms with no reference sequences in NCBI. Abundance of organisms in knotwood, measured as number of OTUs, ranged from 36,272 (29,506 for fungi) to 178,535 (177,484 for fungi) and differed significantly between two trees in a stand and between stands. The highest and lowest average number of fungal OTUs occurred in infected trees with no conks and in trees with conks, respectively. Number of taxa ranged from 171 to 415 and often differed significantly between two trees in one stand and between stands. Greatest diversity occurred in control trees. The number of fungal taxa shared by two trees in one stand was 67–152 and that shared by two stands was 51–141. The majority of fungi were Ascomycota. Those most common in pines affected by P. pini were Coniochaeta hoffmannii and C. fodinicola (19.65%–59.92%). Infundichalara microchona, Leotiomycetes spp. and Rhinocladiella atrovirens were also present. Another common species, Lecanora conizaeoides, occurred most often in control trees (0.30%–8.82%). Porodaedalea pini was detected only sporadically. Non‐culturable fungi were most frequent in the control trees. The greater average abundance and smaller average diversity of fungi in knots of trees infected by P. pini suggest that the pathogen successfully competes with some fungal species and does not inhibit the growth of survivors. Some fungi detected may contribute to production of natural biocides.
