Special Issue Information

Dear Colleagues,

Basidiomycetes, the second most abundant group of fungi on Earth, include human and plant pathogens, ecologically essential fungi such as ectomycorrhizas, and lignocellulose degraders. A good number of basidiomycetes are especially relevant as edible fungi, and some of them are agro-industrially produced for food, proteins, or secondary metabolites with pharmacological applications. Additionally, some basidiomycetes have been extensively studied as model systems of fungal development and mating control. In the last decade, the advances in genome sequencing and analysis have produced a wealth of data covering genome organization and structure, whole-genome transcription in different organisms, developmental stages and culture conditions, epigenetic modifications including methylation and transposon-mediated gene regulation, and proteomic information. All this information can be assembled to produce a corpus of basic knowledge permitting the design of fungal breeding programs aimed at enlarging the number of cultivable species, improving the production of biomass and fungal-derived products, understanding and manipulating pathogenic and mycorrhizal interactions, and exploring the dikaryotic lifestyle that is unique to this type of organism.

This Special Issue in the Journal of Fungi puts together the state of the art on these topics associated with the Genetics and Breeding of Basidiomycetes.

Strain Degeneration in Pleurotus ostreatus: A Genotype Dependent Oxidative Stress Process Which Triggers Oxidative Stress, Cellular Detoxifying and Cell Wall Reshaping Genes

Strain degeneration has been defined as a decrease or loss in the yield of important commercial traits resulting from subsequent culture, which ultimately leads to Reactive Oxygen Species (ROS) production. Pleurotus ostreatus is a lignin-producing nematophagous edible mushroom. Mycelia for mushroom production are usually maintained in subsequent culture in solid media and frequently show symptoms of strain degeneration. The dikaryotic strain P. ostreatus (DkN001) has been used in our lab as a model organism for different purposes. Hence, different tools have been developed to uncover genetic and molecular aspects of this fungus. In this work, strain degeneration was studied in a full-sib monokaryotic progeny of the DkN001 strain with fast (F) and slow (S) growth rates by using different experimental approaches (light microscopy, malondialdehyde levels, whole-genome transcriptome analysis, and chitosan effect on monokaryotic mycelia). The results obtained showed that: (i) strain degeneration in P. ostreatus is linked to oxidative stress, (ii) the oxidative stress response in monokaryons is genotype dependent, (iii) stress and detoxifying genes are highly expressed in S monokaryons with symptoms of strain degeneration, (iv) chitosan addition to F and S monokaryons uncovered the constitutive expression of both oxidative stress and cellular detoxifying genes in S monokaryon strains which suggest their adaptation to oxidative stress, and (v) the overexpression of the cell wall genes, Uap1 and Cda1, in S monokaryons with strain degeneration phenotype indicates cell wall reshaping and the activation of High Osmolarity Glycerol (HOG) and Cell Wall Integrity (CWI) pathways. These results could constitute a hallmark for mushroom producers to distinguish strain degeneration in commercial mushrooms. Full article

Sanghuangporus is a medicinal macrofungal genus typified by S. sanghuang, the very species utilized in traditional Chinese medicines by Chinese ancient people. To facilitate the medicinal application of S. sanghuang, we, for the first time, perform its genome sequencing and analyses from a monokaryon strain. A 33.34 Mb genome sequence was assembled to 26 contigs, which lead to the prediction of 8278 protein-coding genes. From these genes, the potential biosynthesis pathway of sesquiterpenoids was, for the first time, identified from Sanghuangporus, besides that of triterpenoids. While polysaccharides are the main medicinal metabolites in S. sanghuang, flavonoids are especially abundant medicinal metabolites comparing with other medicinal macrofungal groups. From the genomic perspective, S. sanghuang has a tetrapolar heterothallic mating system, and has its special nutritional strategy and advantageous medicinal properties compared with S. baumii and S. vaninii. A phylogenomics analysis indicates that Sanghuangporus emerged 15.39 million years ago and S. sanghuang has a closer phylogenetic relationship with S. baumii than S. vaninii. However, S. sanghuang shares a higher region of synteny and more orthologous genes, including carbohydrate-active enzymes with S. vaninii than S. baumii. A comparative genomics analysis with S. baumii and S. vaninii indicates that species diversification within Sanghuangporus may be driven by the translocation and translocation plus inversion of genome sequences, while the expansion and contraction of gene families may contribute to the host specificity of Sanghuangporus species. In general, the genome sequence of S. sanghuang provides insights into its medicinal application and evolution. Full article
