Special Issue Information

Dear Colleagues,

Endophytic fungi colonize inside plant tissue without causing any adverse effects or symptoms in their host. They are thought to provide several benefits to host plants and improve the host’s ability to adapt to abiotic and biotic stresses. Growing research suggests that endophytic fungi deeply affect plant physiology, development, and metabolism, which has become an indispensable subject in plant research. Endophytic fungi were reported to produce the same pharmacologically important compounds as their host, such as paclitaxel, camptothecin, dicatenarin and others, as well as various enzymes, such as acid proteases, fungal lipases, xylanases, and so on. Therefore, endophytic fungi have great potential for industrial applications in medicine, food, and energy. Furthermore, endophytic fungi bioremediate toxic, recalcitrant compounds by extracellular oxidation, intracellular oxidation, methylation, excretion and storage. Although endophytic fungi have so many potential uses, research on their potential applications is in general fundamental and inadequate. Moreover, most endophytic fungi with minor competitive strengths and more specialized requirements remain undiscovered in conventional cultivation-dependent studies, while DNA-based analysis is limited by insufficient sampling sizes, incorrect sequence data, and misinterpretation of analyses. Hence, studies on fungal endophytes are essential.

This Special Issue, entitled "Advances in Fungal Endophytes Research", aims to present recent research on any aspect of fungal endophytes. Some of its focal points include, but are not limited to, the following:

  1. Diversity and trait of fungal endophytes;
  2. Isolation and applications of secondary metabolites from fungal endophytes;
  3. Potential of fungal endophytes in sustainable agriculture, food, medicine, bioremediation and others;
  4. Cultivation technology and identification method of fungal endophytes;
  5. Functional genomics of fungal endophytes and their applications;
  6. Modification strategies and applications of fungal endophytes;
  7. The macromolecular mechanisms of plant–fungal endophyte interactions.

Reviews, original research, and communications are welcome for submission for this Special Issue.

Polygala crotalarioides, a perennial herbaceous plant found in southwest China, has the potential to be used in the treatment of Alzheimer’s disease. Endophytic fungi that reside within medicinal herbs play an important ecological role in their host plants and can serve as a valuable source for identifying active components. However, little is known about the diversity, and structure of endophytic fungi in P. crotalarioides. In this study, we investigated the community structure and diversity of endophytic fungi in the leaves, stems, and roots of P. crotalarioides at both 1- and 2-year-growth stages using a modern culture-independent method using both culture-independent (high-throughput sequencing, HTS) and culture-based methods. Using HTS, our results revealed that the richness and diversity of endophytic fungi in P. crotalarioides varied depending on the organs and growth stages. Specifically, stems and leaves exhibited significantly higher diversity compared to roots. Additionally, the highest diversity of endophytic fungi was observed in the stems of the 2-year-old plants. At the genus level, Fusarium, Colletotrichum, and Phoma were the most abundant endophytic fungi in 1-year-old samples, while Cercospora, Apiotrichum, and Fusarium were prevalent in 2-year-old samples. A total of 55 endophytic fungal strains belonging to two phyla and 24 genera were isolated from 150 plant tissue segments using culture-based methods. The anti-acetylcholinesterase activity of these isolates was evaluated in vitro and five of them, Phialophora mustea PCAM010, Diaporthe nobilis PCBM027, Fusarium oxysporum LP41, F. oxysporum SR60, and Phoma herbarum SM81, showed strong activity (>50% inhibition rate). These findings will serve as a theoretical basis and practical guide for comprehending the structural composition, biological diversity and bioactivity of endophytic fungi in P. crotalarioides.

Chimonanthus praecox is an aromatic plant that flowers in winter. The composition of the floral volatiles of C. praecox is influenced by different blooming stages, circadian rhythms and species. However, the relationship between floral volatiles and plant endophytic fungi has not received much research attention. Here, we used high-throughput sequencing technology to compare and analyze the changes in the structure and diversity of the endophytic fungal communities in C. praecox under different circadian rhythms (7:00 a.m., 1:00 p.m., and 7:00 p.m.) and in different blooming stages (unopened flowers and opened flowers). The endophytic fungi of C. praecox consisted of nine phyla, 34 classes, 79 orders, 181 families, 293 genera, and 397 species, and Ascomycota was the dominant phylum. Under a diurnal rhythm, the diversity (Chao1 and Shannon indices) of endophytic fungi gradually decreased in the unopened flowers, while an increasing and then decreasing trend was found for the opened flowers. In the different blooming stages, the endophytic fungal diversity was significantly higher at 7:00 a.m. in the unopened flowers compared to the opened flowers. Humidity was the key factors that significantly affected the endophytic fungal diversity and community. Moreover, 11 endophytic fungi were significantly positively or negatively correlated with seven floral volatiles. In conclusion, the community structure and diversity of endophytic fungi in C. praecox were affected by the different blooming stages and circadian rhythms, and a correlation effect related to floral volatiles was found, but there are other possible reasons that were not tested. This study provides a theoretical basis for elucidating the interrelationships between endophytic fungi, floral volatiles, and environmental factors in C. praecox. Full article
