Bioprospecting of endophytes associated with Solanum species: a mini review

Endophytes are considered the repository of bioactive compounds as they contain a wide variety of chemically and structurally diverse secondary metabolites. The endophytes associated with Solanum species have been studied for the last few years. Therefore, the present study aimed to discuss the bioactive compounds produced by endophytes associated with Solanum species and their biological activities. Our study reveals that among the Solanum species, only 13 species have been studied in the context of endophytes so far. Overall, a total number of 98 bioactive compounds have been reported from endophytes associated with Solanum species, of which 64 compounds are from fungi and 34 compounds from bacteria. These bioactive compounds belong to different chemical groups such as sterols, flavonoids, volatiles, and many others and exhibited diverse biological activities including antimicrobial, anticancer, antiparasitic, antioxidants, and plant growth-promoting activity. Moreover, the endophytic fungi were reported to produce two compounds that are often present in the host plants. These condensed data may open the door for further research and provide details on potent endophytes associated with Solanum species.
