Thus, to understand how beta diversity may depend on the conservation status of an area, we aimed to evaluate the structure and diversity (α, β, and γ) of the aquatic fungal community from a subtropical area and how it is distributed in streams from a protected area and from a farmland area. Hence, we compared eight streams inside with eight streams outside of a protected area. This is one of the first studies testing the biotic homogenisation hypothesis for fungi associated with leaf litter in streams. We found new records of fungal species from a global biodiversity hotspot. The gamma diversity of aquatic fungi was surprisingly high. Our analyses indicated a process of environmental homogenisation of streams outside the national park. Intriguingly, neither α nor β diversity differed between areas. Environmental variables presented large differences, especially regarding nutrients, which influence the aquatic fungal community. Altogether, this national park seems to be effective in protecting the environmental heterogeneity of streams to some extent; however, the national park was likely suffering from pollution, which requires further investigation.</p>","PeriodicalId":19111,"journal":{"name":"Mycological Progress","volume":"21 1","pages":""},"PeriodicalIF":2.4,"publicationDate":"2024-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139755288","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since the discovery and description of new species are ongoing, the proportion of undescribed species can be considerable and the taxonomy of the genus goes often through changes. The taxonomy of the genus <em>Tuber</em> would therefore benefit from a periodic review. <em>Tuber</em> species described in Europe in recent decades include <em>Tuber regianum</em>, <em>T. bernardinii</em> and <em>T. magentipunctatum</em>. The common characteristics of these three species are the relatively small-sized spores with alveolate-reticulate ornamentation, a high number of spores per ascus (most frequently 6–8 spores) and small-sized ascomata with a verrucose-papillate or smooth surface. The present study aimed at examining the morphology and ecology of the three species, and providing a detailed taxonomic description of the Regianum clade using a multilocus phylogenetic analysis. In addition to this, we examined whether the apparently plesiomorphic morphological character states of this phylogenetically basal clade are the result of the conservation of ancestral character states. Our results show that in the case of certain morphological traits of the Regianum clade, the apparently plesiomorphic character states are indeed retained ancestral states, while in others, they are convergently reappeared ones. Furthermore, taking an overlook at all <em>Tuber</em> clades, we found that some morphological characters, such as spore length, number of spores per ascus and ascus length, changed together in the same evolutionary patterns, while others transformed in different ways within the genus.</p>","PeriodicalId":19111,"journal":{"name":"Mycological Progress","volume":"89 1","pages":""},"PeriodicalIF":2.4,"publicationDate":"2024-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139755298","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fabaceous plant species host a large number of powdery mildew species belonging to the genus <i>Erysiphe</i>. The affiliation of these species to <i>Erysiphe</i> is readily possible, but they represent a morphologically and taxonomically complicated complex of closely related, morphologically similar species with overlapping traits. Precise morphological examinations along with phylogenetic analyses, including type collections and other representative samples, are needed to solve the complexity of <i>Erysiphe</i> spp. on legumes. In this study, we sequenced a number of collections of powdery mildews on <i>Pisum</i>, <i>Lathyrus</i>, <i>Vicia</i> and <i>Ononis</i> spp., with a special focus on specimens from Iran, to clarify species delimitations within the <i>Erysiphe pisi</i> complex and other <i>Erysiphe</i> species complexes on legumes. Sequences retrieved from powdery mildew on <i>Pisum</i> and <i>Ononis</i> fall into separate, well supported clades.

This study aimed to find out the effectiveness of <i>Trichoderma viride</i> priming on soybean root growth promotion, and enhancement of soil-N and K uptakes under graded fertilization. Soybean seeds were treated with freshly prepared <i>T. viride</i> BHU-2953 talc. Root lignification, indole acetic acid (IAA) production, and activity of 1-aminocyclopropane-1-carboxylate deaminase (ACCD) were determined to observe root growth-promoting activities. A pot experiment was conducted to evaluate root volume, and soil exploration by roots, i.e., the potential volume of influence (PVI), uptakes of N and K, and different physiological attributes at different growth periods of soybean. Results revealed that biopriming enhanced the root lignification, IAA, and ACCD, assisting more soil volume exploration (PVI) for better N and K acquisitions. Biopriming increased the plant biomasses which ultimately, led to more seed yield than untreated soybeans, receiving even higher N-K doses. The PVI correlated well with root volume (<i>r</i>² = 0.95; <i>P</i> &lt; 0.01), explaining good soil-nutrient foraging by bioprimed soybeans.

Substantial doubt has recently been raised concerning the unequivocal suitability of using this sequence information for inferring inter- and intraspecific relationships, as especially the ITS locus was repeatedly shown to harbor high intragenomic plasticity. The evolutionary mechanisms leading to this phenomenon are poorly understood, but this is about to change, owing to the availability of third generation sequencing techniques. The current study attempts a comprehensive analysis of rDNA cistrons in the genomes of over 40 selected species of <i>Hypoxylaceae</i> (<i>Xylariales</i>), using a combination of 2nd generation (Illumina) and 3rd generation sequencing technologies (Oxford Nanopore), along with extensive usage of bioinformatic tools to obtain high-quality genomes. Our findings revealed high intragenomic polymorphisms in distinct <i>Hypoxylaceae</i> species, indicating the presence of deep rDNA paralogs. Phylogenetic inference of the ITS rDNA showed low support for the primary clades within <i>Hypoxylaceae</i>, while inference using the protein encoding gene <i>RPB2</i> showed better support. We also found that proteinogenic genes are not prone to intraspecific and intragenomic polymorphisms as much as the rDNA loci. Our study highlights the limitations of solely relying on the rDNA cistron as a barcode for fungi. We propose <i>TUB2</i> as a new primary barcoding marker for <i>Hypoxylaceae</i> and other <i>Xylariales</i>.
