“…The diversity, species composition, and relative abundance of endophytic fungal communities vary significantly among different tissues and exhibit tissue specificity [ 52 , 53 ]. The distribution of endophytic fungi within plant tissues is influenced by several factors, such as nutrients, salinity, chemical composition, and environmental conditions of the host plants [ 54 ]. In our study, it was found that the diversity of endophytic fungi in the underground parts of A. speciosum and A. aureum was significantly higher than that in the aboveground parts.…”

Microbial communities are an important component of mangrove ecosystems. In order to reveal the diversity of endophytic fungi in the mangrove ferns Acrostichum speciosum and A. aureum in China, the internal transcribed spacer (ITS) regions of endophytic fungi in four plant tissues (leaves, petioles, roots, and rhizomes) from three locations (Zhanjiang, Haikou, and Wenchang) were sequenced. The richness, species composition, and community similarity were analyzed. The main results are as follows: the dominant fungi in A. speciosum and A. aureum belonged to the phyla Ascomycota and Basidiomycota, accounting for more than 75% of the total identified fungi; in terms of species composition at the operational taxonomic unit (OTU) level, the endophytic fungi in A. aureum were more diverse than those in A. speciosum, and the endophytic fungi in rhizomes were more diverse than in other tissues. In Zhanjiang, both A. speciosum and A. aureum showed the richest diversity of endophytic fungi, both at the OTU classification level and in terms of species composition. Conversely, the richness of endophytic fungi in the samples of A. speciosum from Wenchang and Haikou is extremely low. The regional differences in dominant fungi increase with the degrading of taxonomic levels, and there were also significant differences in the number of unique fungi among different origins, with Zhanjiang samples having a larger number of unique fungi than the other locations. There were significant differences in the dominant fungi among different tissues, with Xylariales being the dominant fungi in rhizomes of A. speciosum and Hypocreales being the dominant fungi in the petioles, roots, and rhizomes of A. aureum. Overall, the community similarity of endophytic fungi among locations is moderately dissimilar (26–50%), while the similarity between tissues is moderately similar (51–75%). The low diversity of endophytic fungi could be one of the main reasons for the endangerment of A. speciosum. The protection of the diversity of endophytic fungi in the underground parts of A. speciosum is essential for the conservation of this critically endangered mangrove fern.

Fungi are a distinguished category of microorganisms that belong to a distinct kingdom. Biotechnological methods have significant contributions in several domains and shown generosity in manufacturing diverse metabolites that belong to distinct chemical classes and possess varying bioactivity and/or industrial applications. The mentioned advantages have fostered the habit of screening for fungus from unexplored origins. In this study, we conducted a screening to identify fungus from a distant bat cave in Assiut governorate, Egypt. Specifically, we focused on endophytic fungi found in flower petals and endolichenic fungi found in lichen. As a consequence, 17 distinct fungal species were isolated, which can be classified into 12 different fungal genera. Furthermore, the morphological and microscopic identification of the 4 isolates was unattainable due to their sterile mycelia appearance. Therefore, four individual specimens were genetically identified by sequencing their ITS regions as Rhizomucor miehei NRCWA, Penicillium chrysogenum NRCWA, P. polonicum NRCWA, and P. crustosum NRCWA. The corresponding accession codes for these identifications are PP422033, PP422038, PP422039, and PP422040, respectively. This study is the initial documentation of the extraction of endophytic and endolichenic fungi from Chrysothrix candelaris specimens obtained from Egypt. Exploring and identifying fungi from unexplored sources can help uncover powerful metabolites that have potential applications in several biotechnological and industrial sectors.

The genus Trichoderma is multicultural soil-borne fungi found in different ecosystems. They are highly successful colonizers of their habitats. Genus Trichoderma is capable of dealing with various environments such as compost, agricultural soils, rhizosphere, and waste material. Therefore, different strains of Trichoderma have been applied in agriculture, bioremediation, waste management, and biotechnology. Many Trichoderma species act as biological control agents and plant growth promoters. Additionally, the genus Trichoderma is a new fungal source for the production of cyclosporin A as well as various hydrolytic enzymes with industrial importance.
