Fungal endophytes have been found to exist in many plant species and appear to be important to their plant hosts. However, the diversity and biological activities of these fungi remain largely unknown. Zanthoxylum simulans Hance, a popular natural spice and medicinal plant, commonly known as Szechuan pepper or Chinese-pepper, grows on Kinmen Island, Taiwan. In this study, leaf and stem samples of Z. simulans, collected in summer and winter, were screened for antimicrobial and anti-inflammatory metabolite-producing endophytic fungi. A total of 113 endophytic strains were isolated and cultured from Z. simulans, among which 23 were found to possess antimicrobial activity, belonging to six fungal genera: Penicillium (26.09%, 6), Colletotrichum (21.74%, 5), Diaporthe (21.74%, 5), Daldinia (17.39%, 4), Alternaria (8.70%, 2), and Didymella (4.34%, 1). We also found that the number of species with antimicrobial activity and their compositions differed between summer and winter. Our study demonstrated that Z. simulans might contain large and diverse communities of endophytic fungi, and its community composition varies seasonally. In addition, fungal endophytes produce antimicrobial agents, which may protect their hosts against pathogens and could be a potential source of natural antibiotics.

Introduction Oral verrucous carcinoma (OVC), a low-grade variation of oral squamous cell carcinoma (OSCC), is distinguished by endophytic development and a pebbly, mammillated surface. OVC, often referred to as Ackerman's tumor, has been known to involve lymph nodes but rarely spreads to regional and distant locations; when the primary tumor grows, it frequently involves surrounding tissues. Histopathologically, it has a thicker basement membrane, many reduplications, and a large area of inflammatory infiltration that resembles OSCC.

Zea mays L. (Maize) is one of the most crucial world's crops, for their nutritional values, however, the water scarcity and consequent soil salinization are the major challenges that limit the growth and productivity of this plant, particularly in the semi-arid regions in Egypt. Recently, biopriming has been recognized as one of the most efficient natural-ecofriendly approaches to mitigate the abiotic salt stress on plants.

The rapid decline of significant plant species due to deforestation and slow regrowth has endangered many trees that are crucial for producing life-saving medications. This dual crisis of conserving plant biodiversity while meeting pharmaceutical demands necessitates innovative solutions. Endophytic fungi, naturally occurring symbionts within plants, present an eco-friendly and economically viable alternative.

Root nodule symbiosis is traditionally recognized in the Fabales, Fagales, Cucurbitales, and Rosales orders within the Rosid I clade of angiosperms. However, ambiguous root nodule formation has been reported in Zygophyllaceae and Roystonea regia (Arecaceae), although a detailed analysis has yet to be conducted. We aimed to perform morphological analyses of root structures in these plants and utilize metagenomic techniques to identify and characterize the bacterial populations within the nodule-like structures.

This study investigates a novel antimicrobial peptide AtR905 derived from the endophytic fungus , which was successfully expressed in , purified, and characterized, and highlighted as a promising potential biocontrol agent against various plant pathogens. The results indicated AtR905 exhibited broad-spectrum antimicrobial activities against key pathogens such as and with very low minimal inhibitory concentrations (MICs). Stability tests confirmed that AtR905 retains its antimicrobial properties under varying thermal, pH, and UV conditions.
