“…The study revealed that both the year and season exerted a substantial influence on the abundance of fungal genera in plant leaves. Furthermore, in comparison to species-related factors, the α and β diversity indices were found to be more strongly affected by the year [59]. The microbial community in this coniferous forest was also shown to vary seasonally, and plant photosynthesis appeared to be a major driver of seasonality [60].…”

Microorganisms are an important component of global biodiversity and play an important role in plant growth and development and the protection of host plants from various biotic and abiotic stresses. However, little is known about the identities and communities of endophytic fungi inhabiting cultivated medicinal plants in the farmland ecosystem. The diversity and community composition of the endophytic fungi of cultivated medicinal plants in different hosts, tissue niches, and seasonal effects in the farmland of Northern China were examined using the next-generation sequencing technique. In addition, the ecological functions of the endophytic fungal communities were investigated by combining the sequence classification information and fungal taxonomic function annotation. A total of 1025 operational taxonomic units (OTUs) of endophytic fungi were obtained at a 97% sequence similarity level; they were dominated by Dothideomycetes and Pleosporales. Host factors (species identities and tissue niches) and season had significant effects on the community composition of endophytic fungi, and endophytic fungi assembly was shaped more strongly by host than by season. In summer, endophytic fungal diversity was higher in the root than in the leaf, whereas opposite trends were observed in winter. Network analysis showed that network connectivity was more complex in the leaf than in the root, and the interspecific relationship between endophytic fungal OTUs in the network structure was mainly positive rather than negative. The functional predications of fungi revealed that the pathotrophic types of endophytic fungi decreased and the saprotrophic types increased from summer to winter in the root, while both pathotrophic and saprotrophic types of endophytic fungi increased in the leaf. This study improves our understanding of the community composition and ecological distribution of endophytic fungi inhabiting scattered niches in the farmland ecosystem. In addition, the study provides insight into the biodiversity assessment and management of cultivated medicinal plants.

“…High-throughput amplicon sequencing (HTAS) and bioinformatics tools have been well applied in analyzing fungal diversity and interpreting the results perfectly, breaking through the shortcomings of traditional culture-dependent methods, which are difficult Noteworthily, bioinformatics analysis plays a crucial role in fungal diversity analysis. High-throughput amplicon sequencing (HTAS) and bioinformatics tools have been well applied in analyzing fungal diversity and interpreting the results perfectly, breaking through the shortcomings of traditional culture-dependent methods, which are difficult in application when culturing some micro-organisms [63][64][65]. The Divisive Amplicon Denoising Algorithm (DADA2) and the Quantitative Insights Into Microbial Ecology (QIIME) are helpful for data processing and data analysis [66,67].…”

In a long-term evolution, fungal endophytes have formed a mutually beneficial relationship with host plants. Therefore, what roles do fungal endophytes play in the growth and development of rice, one of the major food crops in the world, and agricultural production? This mini-review aims to highlight the diversity, identification, colonization, function, and mechanism of action of endophytic fungi isolated from rice tissues through a literature review; comprehensively expound the interaction mechanism between rice fungal endophytes and their hosts in stimulating the growth of rice plants and alleviating biological and abiotic stresses on plants; and contribute new ideas for rice production and a sustainable rice industry. Additionally, rice fungal endophytes, as a new resource, have broad prospects in the development of biopesticides, biocontrol agents, and new medicine.

“…Wiehler is a rupicolous species often found growing in rock crevices in highland grasslands of the Brazilian tropical forests, as well as it has been cultivated in vitro, in plants and calli forms, displaying potent antioxidant capacity and the ability to produce secondary metabolites in large quantities. 11,21 Photodynamic therapy (PDT) has aroused growing interest as a therapeutic alternative in some types of cancer, as it is a noninvasive, selective therapy, that can accurately target early diagnosed tumors, has moderate or minimal side effects, does not cause harm to healthy tissue, and improves the quality and longevity of patients in advanced stages of the disease. [23][24][25][26][27] This therapy is based on the administration of a light sensitive (photosensitizer), either systemically or topically substance, followed by low-dose irradiation with visible light of a suitable wavelength.…”

Photodynamic therapy (PDT) has been used for various purposes, including as an antitumor resource in a noninvasive therapy with minimal side effects. Sinningia magnifica (Otto & A. Dietr.) Wiehler is a rupicolous plant found in rock crevices in Brazilian tropical forests. Initial studies indicate the presence of phenolic glycosides and anthraquinones in species of the genus Sinningia (Generiaceae family). It is known that anthraquinones are natural photosensitizers with potential PDT applications. This led us to investigate the potential compounds of S. magnifica for use as a natural photosensitizer against the melanoma (SK‐MEL‐103) and the prostate cancer (PC‐3) cell lines in a bioguided study. Our results showed that singlet oxygen production by the 1,3‐DPBF photodegradation assay greatly increased in the presence of crude extract and fractions. The biological activity evaluation showed photodynamic action against melanoma cell line SK‐MEL‐103 and prostate cell line PC‐3. These results suggest the presence of potential photosensitizing substances, as demonstrated in this in vitro antitumor PDT study by the naphthoquinones Dunniol and 7‐hydroxy‐6‐methoxy‐α‐dunnione for the first time. Naphthoquinones, anthraquinones and phenolic compounds were identified in the crude extract by UHPLC–MS/MS analysis, motivating us to continue with the bioguided phytochemical study aiming to discover more photochemically bioactive substances in Gesneriaceae plants.
