“…SaCS20." Endophytes use several multiple mechanisms to enable the uptake of nutrients in the edible portions of plants (113,114). Zn-solubilizing endophytes may be a better biofortifying agent to increase the Zn localization in the eatable portion of wheat (9,31), rice (108), and chickpea (16), thus presenting an alternative approach into the current strategies for biofortification.…”

A contemporary approach to bacterially mediated zinc (Zn) biofortification offers a new dimension in the crop improvement program with better Zn uptake in plants to curb Zn malnutrition. The implication of Zn solubilizing bacteria (ZSB) represents an inexpensive and optional strategy for Zn biofortification, with an ultimate green solution to enlivening sustainable agriculture. ZSB dwelling in the rhizospheric hub or internal plant tissues shows their competence to solubilize Zn via a variety of strategies. The admirable method is the deposition of organic acids (OAs), which acidify the surrounding soil environment. The secretion of siderophores as a metal chelating molecule, chelating ligands, and the manifestation of an oxidative–reductive system on the bacterial cell membrane are further tactics of bacterially mediated Zn solubilization. The inoculation of plants with ZSB is probably a more effective tactic for enhanced Zn translocation in various comestible plant parts. ZSB with plant growth-enhancing properties can be used as bioelicitors for sustainable plant growth via the different approaches that are crucial for plant health and its productivity. This article provides an overview of the functional properties of ZSB-mediated Zn localization in the edible portions of food crops and provides an impetus to explore such plant probiotics as natural biofortification agents.

“…In addition, it was shown that both Bl1 and Ech4 isolates inhibited the B. cinerea mycelial growth by antibiosis, similar to other endophytic fungi; for example, fungi isolated from Theobroma cacao showed antibiosis against pathogens such as Moniliophthora roreri and Phytophthora palmivora [45], and endophytic fungi isolated from Aloe vera also inhibited by antibiosis the mycelial growth of Fusarium oxysporum [46]. The inhibition halo found in both isolates indicates that the antifungal activity of the obtained endophytic fungi is due to the secretion of diffusible secondary metabolites to the culture medium.…”

Botrytis cinerea is one of the most important phytopathogens in agriculture worldwide, infecting economically important crops. The main control of this fungus is by synthetic fungicides, causing the selection of resistant isolates. Compounds produced by endophytic fungi have been shown to have antifungal activity against this pathogen and can be used as an alternative to synthetic fungicides. The aim of this work was to isolate endophytic fungi from Chilean foothills in the Metropolitan Region. Ten fungi were isolated from Echinopsis chiloensis and Baccharis linearis, however, only two isolates inhibited the mycelial growth of B. cinerea by antibiosis and were identified as Epicoccum sp. and Pleosporales sp. Extracts at 200 mg L−1 from Epicoccum sp. and Pleosporales sp. showed antifungal activity against B. cinerea of 54.6 and 44.6% respectively. Active compounds in the Epicoccum sp. extracts were mainly alkaloids and phenolic compounds; meanwhile, in the Pleosporales sp. extracts, terpenes and/or saponins were responsible for the antifungal activity.

“…Fungal endophytes isolated from Ocimum sanctum were evaluated against Rhizoctonia solani, Fusarium oxysporum, Colletotrichum falcatum, and Helminthosporium maydis. A total of nine fungi were isolated, but none of them showed inhibition of mycelial growth (Yadav et al, 2015).…”

Endophytes are a rich source of secondary metabolites such as tannins, phenolics, and alkaloids. Endophytic fungi have potential as antioxidants, antimicrobials, anticancer agents, antidiabetic agents, hepatoprotectants, growth promoters, and immunomodulators. Recent studies have shown that endophytes are a valuable source of undiscovered biomolecules. As a result, endophytic isolates from medicinal plants can be used in the pharmaceutical, industrial, and agricultural sectors. Ocimum species, for example, have several medicinal properties and are used in traditional medicine. Fungal endophytes have a strong association with Ocimum plants. Previous research has shown that the fungal endophytes of Ocimum sanctum produce phytochemicals such as alkaloids, terpenoids, cardiac glycosides, flavonoids, terpenes, and volatile compounds. Additionally, fungal endophytes have a direct impact on the medicinal value of the genus Ocimum. This review aimed to discuss the pharmacological properties and diversity of endophytic fungi associated with the genus Ocimum.
