“…The presence of a large amount of biologically active substances in species of the genus Cornus not only makes them a valuable medicinal raw material but also increases their resistance to many stress factors (Ma et al, 2014;Biaggi et al, 2018;Bayram and Ozturkcan, 2020;Demir et al, 2020;Levon and Klymenko, 2021).…”

The genetic fund of the cornelian cherry (Cornus mas L.) cultivars at the M.M. Gryshko National Botanical Garden (NBG), National Academy of Sciences of Ukraine includes more than 100 genotypes collected from wild and cultivated plants in Ukraine, and cultivars of Bulgarian, Slovak, English, Austrian and Georgian selection. The genetic fund of the cornelian cherry of the NBG presents a rich variety of biological and economic properties. The fruits of C. mas are valued in the food industry and medicine mainly due to their high content of bioactive compounds such as vitamin C, carotenoids, and anthocyanins. C. mas fruits also have antioxidant activity. We have given the pomological characteristics of 21 studied cultivars of C. mas, and also determined the content of iridoids. Cultivars of C. mas with early, middle, and late fruit ripening periods were studied. To determine the content of iridoids, a spectrophotometric method was used, which consists of the interaction of an iridoid compound with hydroxylamine to form an oxime. The resulting oxime is capable of forming a coordination compound with ferric iron cations. As a result of the study, it was found that the content of iridoids in the fruits of C. mas has a significant difference in cultivars. Among the early ripening cultivars of C. mas, the most promising as a source of iridoids are Pervenets and Samofertylnyi, among the cultivars of C. mas with an average fruit ripening period is Yevgenia, and among the cultivars of C. mas with a late ripening period of fruits, the most promising cultivars are Sokoline and Yuvileinyi Klymenko. These most promising cultivars should be noted for use in the food and medical sectors of the national economy.

Salinity stress, a significant global abiotic stress, is caused by various factors such as irrigation with saline water, fertilizer overuse, and drought conditions, resulting in reduced agricultural production and sustainability. In this study, we investigated the use of halotolerant bacteria from coastal regions characterized by high salinity as a solution to address the major environmental challenge of salinity stress. To identify effective microbial strains, we isolated and characterized 81 halophilic bacteria from various sources, such as plants, rhizosphere, algae, lichen, sea sediments, and sea water. We screened these bacterial strains for their plant growth-promoting activities, such as indole acetic acid (IAA), phosphate solubilization, and siderophore production. Similarly, the evaluation of bacterial isolates through bioassay revealed that approximately 22% of the endophytic isolates and 14% of rhizospheric isolates exhibited a favorable influence on seed germination and seedling growth. Among the tested isolates, GREB3, GRRB3, and SPSB2 displayed a significant improvement in all growth parameters compared to the control. As a result, these three isolates were utilized to evaluate their efficacy in alleviating the negative impacts of salt stress (150 mM, 300 mM, and seawater (SW)) on the growth of wheat plants. The result showed that shoot length significantly increased in plants inoculated with bacterial isolates up to 15% (GREB3), 16% (GRRB3), and 24% (SPSB2), respectively, compared to the control. The SPSB2 strain was particularly effective in promoting plant growth and alleviating salt stress. All the isolates exhibited a more promotory effect on root length than shoot length. Under salt stress conditions, the GRRB3 strain significantly impacted root length, leading to a boost of up to 6%, 5%, and 3.8% at 150 mM, 300 mM, and seawater stress levels, respectively. The bacterial isolates also positively impacted the plant’s secondary metabolites and antioxidant enzymes. The study also identified the WDREB2 gene as highly upregulated under salt stress, whereas DREB6 was downregulated. These findings demonstrate the potential of beneficial microbes as a sustainable approach to mitigate salinity stress in agriculture.

Licorice (Glycyrrhiza glabra L.) is an industrial medicinal plant that is potentially threatened by extinction. In this study, the effects of salinity (0 and 200 mM sodium chloride (NaCl)) and Azotobacter inoculation were evaluated on 16 licorice accessions. The results showed that salinity significantly reduced the fresh and dry biomass (FW and DW, respectively) of roots, compared to plants of the control group (a decrease of 15.92% and 17.26%, respectively). As a result of bacterial inoculation, the total sugar content of roots increased by 21.56% when salinity was applied, but increased by 14.01% without salinity. Salinity stress increased the content of glycyrrhizic acid (GA), phenols, and flavonoids in licorice roots by 104.6%, 117.2%, and 56.3%, respectively. Integrated bacterial inoculation and salt stress significantly increased the GA content in the accessions. Bajgah and Sepidan accessions had the highest GA contents (96.26 and 83.17 mg/g DW, respectively), while Eghlid accession had the lowest (41.98 mg/g DW). With the bacterial application, the maximum amounts of glabridin were obtained in Kashmar and Kermanshah accessions (2.04 and 1.98 mg/g DW, respectively). Bajgah and Kashmar accessions had higher amounts of rutin in their aerial parts (6.11 and 9.48 mg/g DW, respectively) when their roots were uninoculated. In conclusion, these results can assist in selecting promising licorice accessions for cultivation in harsh environments.
