Special Issue Information

Dear Colleagues,

Plants have an outstanding ability to establish relationships with a vast array of microbes, either horizontally or vertically acquired. Fungi are prominent, diversified members of the plant microbiome, and the establishment of fungal endophytism in plant roots is dated back to 450 million years ago. Endophytic fungi are asymptomatic colonizers of plant tissues and can be found intracellularly or in the intercellular space, a niche that is reserved for them for a part or the totality of the plant life cycle. This ubiquitous, mutualistic interaction is supported by the fungal ability to increase plant growth and stress resistance, mainly through direct nutrient exchange, the production of hormone-like molecules, effector-mediated priming of immune responses, and the production of secondary metabolites that mimic host-derived metabolites. Molecular tools fueled the current knowledge about endophytic fungi, some of which cannot be reproduced axenically. The description of fungal endophytes is fundamental from an evolutionary perspective to detect common patterns across the plant kingdom, for application in agriculture and medicine, but also because mutualistic strains are often close relatives of pathogenic or mycotoxigenic ones. In this Special Issue, we welcome original and review papers regarding the characterization of fungal endophytes, with a focus on molecular approaches.

Many orchid species are endangered due to anthropogenic pressures such as habitat destruction and overharvesting, meanwhile, all orchids rely on orchid mycorrhizal fungi (OMF) for seed germination and seedling growth. Therefore, a better understanding of this intimate association is crucial for orchid conservation. Isolation and identification of OMF remain challenging as many fungi are unculturable. In our study, we tested the efficiency of both culture-dependent and culture-independent methods to describe OMF diversity in multiple temperate orchids and assessed any phylogenetic patterns in cultivability. The culture-dependent method involved the cultivation and identification of single pelotons (intracellular hyphal coils), while the culture-independent method used next-generation sequencing (NGS) to identify root-associated fungal communities. We found that most orchid species were associated with multiple fungi, and the orchid host had a greater impact than locality on the variability in fungal communities. The culture-independent method revealed greater fungal diversity than the culture-dependent one, but despite the lower detection, the isolated fungal strains were the most abundant OMF in adult roots. Additionally, the abundance of NGS reads of cultured OTUs was correlated with the extent of mycorrhizal root colonization in orchid plants. Finally, this limited-scale study tentatively suggests that the cultivability character of OMF may be randomly distributed along the phylogenetic trees of the rhizoctonian families. Full article

Round spot is a destructive disease that limits of Panax notoginseng production in China. However, the genetic diversity of its etiological agent Mycocentrospora acerina has yet to be studied. In this work, firstly, we developed 32 M. acerina polymorphic microsatellite markers using MISA and CERVUS 3.0 and selected 14 for further analysis. Then, we studied the genetic diversity of 187 isolates collected from P. notoginseng round spot using simple sequence repeat markers and polyacrylamide gel electrophoresis. The genetic diversity ranged from 0.813 to 0.946, with 264 alleles detected at the 14 microsatellite loci. The expected average heterozygosity was 0.897. Full article

The study examines the intricate relationship between plants and the endophytic fungi inhabiting their tissues. These fungi harmoniously coexist with plants, forming a distinct symbiotic connection that has caught scientific attention due to its potential implications for plant health and growth. The diverse range of bioactive compounds produced by these fungi holds significant promise for human health. The review covers various aspects of this topic, starting by introducing endophytic microorganisms, explaining their colonization of different plant parts, and illuminating their potential roles in enhancing plant defense against diseases and promoting growth. The review emphasizes the widespread occurrence and diversity of these microorganisms among plant species while highlighting the complexities and significance of isolating and extracting bioactive compounds from them. It focuses on the health benefits of these bioactive compounds, including their capacity to exhibit antioxidant, anti-inflammatory, antimicrobial, and anticancer effects. The review delves into the mechanisms behind these health-promoting effects, spotlighting how the compounds interact with cellular receptors, signaling pathways, and gene expression. In conclusion, the review provides a comprehensive overview of health-promoting bioactive compounds from plant endophytic fungi. It outlines their multifaceted impact, potential applications, and future research avenues in health and medicine. Full article
