Background and objectives: Hippophae rhamnoides L. (sea buckthorn) is a deciduous shrub or tree in the Elaeagnaceae family. Sea buckthorn is one of the native species of the Turani regions of Iran, with limited and scattered habitats in Gachsar, Haraz, Arasbaran, Khoy, and Alamut. An old miraculous plant, it is highly regarded for its richness in bioactive and nutritional substances. Hippophae rhamnoides is one of the valuable precursor species in terms of nitrogen fixation for the soil. It is a storage shrub resistant to cold, drought, and low-cover environments. Sea buckthorn contains nearly 200 nutritional and bioactive compounds. This plant's fruits are rich in lipids, carotenoids, ascorbic acid, and flavonoids. The purpose of the present study, considering the high medicinal and ecological importance of the Sea buckthorn plant and the few studies in Iran, especially in the field of phytochemical compounds of this valuable plant, is to introduce the Sea buckthorn plant, its phytochemical compounds, and some of their uses in the pharmaceutical and food industries. Materials and methods: This article contains scientific papers published between 2001 and 2022 from Google Scholar, Web of Science, Scopus, and PubMed.Results: All parts of sea buckthorn (fruits, leaves, stems, branches, roots, and thorns) have been traditionally used in medicine and food supplements. Sea buckthorn leaves, fruits, and oils are rich in macro and microelements, vitamins A, C, E, lipids, carotenoids, amino acids, unsaturated fatty acids, and phenols. In recent years, there have been several reports on the medicinal activities of sea buckthorn, including its anti-cancer, anti-inflammatory, antimicrobial, and antiviral activities and its ability to protect the heart and blood vessels. The oil obtained from the seeds and fruit includes bioactive compounds such as palmitoleic acid (omega 7), a part of skin lipids, and stimulates epidermis repair and healing wounds. Flavonol glycosides are one of the most abundant phenolic compounds in sea buckthorn. Flavonoids are antioxidants in sea buckthorn that prevent blood platelet accumulation and cancer cell spread. They improve blood circulation and reduce inflammation. As an antioxidant, antimicrobial, and other natural additive, sea buckthorn is used in various food products. In addition, it is used in diverse forms, such as oil, dried powder, fruit juice, pills, drinks, fruit, and tea. Conclusion: Besides its high nutritional value as a food, the genus Hippophae has several economic advantages as a raw material for cosmetics, food, pharmaceutical industries, and environmental protection. Due to its high tolerance to cold, drought, salinity, and alkalinity and the ability to fix nitrogen in the soil, it is an ideal product for protecting soil and water and windbreaks on marginal lands prone to soil erosion.

Piriformospora indica is one of the growth-promoting microorganisms that can stimulate growth and increase plant tolerance in adverse environmental conditions. To evaluate the effects of P. indica inoculation on some vegetative, physiological, biochemical, and nutrient acquisition parameters and essential oil content of Origanum vulgare L. ssp. vulgare, a pot experiment was conducted in a completely randomized design with three replications. Treatments included control (without inoculation) and inoculation with P. indica. The results showed that inoculation with P. indica increased growth parameters, chlorophyll index, total phenols and total flavonoids content, essential oil content, and nutrients uptake of iron, potassium, and phosphorus singnificantly. The highest and lowest amounts for aerial parts fresh yield (3.92 and 3.06 g plant-1), aerial parts dry yield (1.12 and 0.78 g plant-1), chlorophyll index (47 and 42.23), total phenol (4.88 and 2.96 mg GAE g-1 FW), total flavonoids (0.52 and 0.23 mg QE g-1 FW), essential oil content (1.43 and 1.01%), phosphorus (0.41 and 0.35%), potassium (3.8 and 2.6%), and iron (219 and 180 mg kg-1) were obtained in the plants inoculated with fungus and non-inoculated plants, respectively. Inoculation with P. indica decreased the amount of major essential oil compounds such as carvacrol and thymol and increased the amount of ρ-cymene, carvacrol methyl ether, and γ-terpinene compared to the control. Overall, the findings of this study showed that inoculation with growth-promoting microorganisms can improve the morphological and phytochemical traits of oregano by improving nutrients uptake.

To study the influence of arbuscular mycorrhizal (AM) fungi inoculation and drought stress on growth, chlorophyll content and phosphorus uptake of basil (Ocimum basilicum L.), a pot experiment was conducted using a factorial based on randomized complete blocks design with four replications. The factors were mycorrhizal inoculation (non-inoculated and inoculated with Glomus mosseae T.H. Nicolson & Gerd. and Glomus intraradices N.C. Schenck & G.S. Sm) and three irrigation regimes (irrigation intervals were every 4, 8 and 12 days). The results showed that drought stress had significant effects on evaluated characteristics. As with decrease of the soil water content, plant height, stem diameter, number and area of leaves, number of axillary shoot, root dry weight, fresh and dry herb yield, chlorophyll content, P concentration in leaves and root colonization decreased. Also, AM fungi inoculation had significant effects on growth parameters and P uptake. Plants inoculated with AM fungi had higher growth, yield and P uptake than non-inoculated plants under droughtstress and non-stress conditions. G. mosseae was more effective than G. intraradices in alleviation of drought stress. It could be concluded that AM fungi are able to enhance the growth and yield of basil under drought stress condition through enhancing P uptake.
