“…Halophytes can naturally grow in or even depend on high NaCl environment. For example, species of Atriplex and Salicornia can grow in an environment of up to 1000 mM NaCl [10]. Most crops are glycophytes, their growth may be severely inhibited by the low Na + concentration, which means they need fresh water.…”

Background The molecular mechanism of forest trees responding to salt stress remains poorly understood. As a fast-growing and widely adapted tree species, Populus alba is planted in the world. Understanding the molecular mechanism of P. alba responding to salt stress is helpful to improve the yield of P. alba artificial forest in salinized land. Results This study investigated the phenotypic and physiological characteristics of P. alba seedlings under 300 mM NaCl stress. After seven days of salt stress, the leaves of P. alba turned yellow and fell off. Whether under normal growth conditions or salt stress, CAT activities in roots were significantly higher than that in leaves. The root viability of P. alba decreased significantly within 2 h of salt treatment, but gradually increased after 2 h of salt treatment. Intercellular CO2 concentration of leaves of P. alba increased significantly after 72 h of salt treatment, while other photosynthetic parameters decreased significantly after 72 h of salt stress. Chlorophyll a and chlorophyll b in leaves of P. alba decreased gradually after 9 h of salt stress. The ratio of Na+/K+ in roots and leaves of P. alba gradually increased after 1 and 2 h of salt stress, respectively. ABA and cytokinin contents in roots and leaves of P. alba under salt stress were increased significantly. Time-series transcriptomes of roots, stems, leaves, and apical buds of P. alba under NaCl stress were analyzed. Based on gene expression, physiological and biochemical data in P. alba under salt stress, we performed weighted gene co-expression network analysis. Thirty-two candidate key genes of P. alba responding to salt stress were identified. Twenty-four candidate key genes showed salt tolerance in Saccharomyces cerevisiae. Especially for the four genes (Poalb01G005590, Poalb16G007310, Poalb01G036340, and Poalb06G010440), each exhibited strong tolerance to different kinds of salt stress. Conclusion The results of this study provide a new insight into the molecular mechanism of trees responding to salt stress.

Relevance. Sphallerocarpus gracilis (Besser ex Trevir.) Koso-Pol. (Umbelliferae) is a biennial pubescent plant widely used in the practice of Oriental medicine. Research on S. gracilis is attracting increasing attentiom due to its potential biological zctivities: antioxidant, hepatoprotective effects, anticancer properties, essential oils exhibit significant antimicrobial properties. Material and methods. Essential oils of the aerial part and roots of the Sphallerocarpus gracilis from Mukhorshibirsky district of the Republic of Buryatia, collected during the period of mass flowering (August, 2022), were studied. Essential oils from the herbs and roots were isolated by hydrodistillation method. The content of essential oils was found by volumetric method. The qualitative composition and quantitative content of essential oils components were determined by gas chromatography-mass spectrometry method. Results. The qualitative composition and quantitative content of essential oils components of the aerial part and roots of Sphallerocarpus gracilis from Buryatian flora studied for the first time. The main components of the essential oils of the aerial part are geranyl tiglate (7.56%) and apiol (71.83%); the roots are γ-terpinene (45.17%), p-cymene (9.38%) and trans-asarone (13.29%). Conclusion. It has been shown that the aerial part of S. gracilis is a rich source of apiol, while the roots – compounds of monoterpene nature.
