“…Blue light was reported to be involved in the regulation of GS-related gene (GS) expression at the transcriptional and translational levels via phytochromes [74]. Therefore, when combined with other light spectra, blue light may enhance nitrate assimilation by upregulating NR and GS transcriptions and concomitantly enhancing NR and GS activities through all or part of the phytochrome-mediated signaling pathway [59,74]. However, until now, the molecular mechanisms by which blue light is involved in the regulation of nitrate assimilation are still not fully understood.…”

Excessive accumulation of nitrates in vegetables is a common issue that poses a potential threat to human health. The absorption, translocation, and assimilation of nitrates in vegetables are tightly regulated by the interaction of internal cues (expression of related genes and enzyme activities) and external environmental factors. In addition to global food security, food nutritional quality is recognized as being of strategic importance by most governments and other agencies. Therefore, the identification and development of sustainable, innovative, and inexpensive approaches for increasing vegetable production and concomitantly reducing nitrate concentration are extremely important. Under controlled environmental conditions, optimal fertilizer/nutrient element management and environmental regulation play vital roles in producing vegetables with low nitrate content. In this review, we present some of the recent findings concerning the effects of environmental factors (e.g., light, temperature, and CO2) and fertilizer/nutrient solution management strategies on nitrate reduction in vegetables grown under controlled environments and discuss the possible molecular mechanisms. We also highlight several perspectives for future research to optimize the yield and nutrition quality of leafy vegetables grown in controlled environments.

“…exposure resulting in enhanced NO 3 absorption and translocation in leaves (Stuiver et al 2014). Plants have well-developed S and N pathways, which are functionally convergent as the availability of one nutrient regulates the other (Kaur et al 2013). A marked increment in P uptake was observed in plants treated with S-fertilizers.…”

The present study involved two pot experiments to investigate the response of mung bean to the individual or combined SO42− and selenate application under drought stress. A marked increment in biomass and NPK accumulation was recorded in mung bean seedlings fertilized with various SO42− sources, except for CuSO4. Compared to other SO42− fertilizers, ZnSO4 application resulted in the highest increase in growth attributes and shoot nutrient content. Further, the combined S and Se application (S + Se) significantly enhanced relative water content (16%), SPAD value (72%), photosynthetic rate (80%) and activities of catalase (79%), guaiacol peroxidase (53%) and superoxide dismutase (58%) in the leaves of water-stressed mung bean plants. Consequently, the grain yield of mung bean was markedly increased by 105% under water stress conditions. Furthermore, S + Se application considerably increased the concentrations of P (47%), K (75%), S (80%), Zn (160%), and Fe (15%) in mung bean seeds under drought stress conditions. These findings indicate that S + Se application potentially increases the nutritional quality of grain legumes by stimulating photosynthetic apparatus and antioxidative machinery under water deficit conditions. Our results could provide the basis for further experiments on cross-talk between S and Se regulatory pathways to improve the nutritional quality of food crops.

Against the background of global climate change, drought stress has become one of the environmental limiting factors that can significantly influence the growth and development of crop plants. Drought stress conditions also cause changes in plant physiological and metabolic processes. The influence of soil drought on the mineral composition of the leaves of two Actinidia species with С3-type photosynthesis, namely, Actinidia argutа (Siebold & Zucc.) Planch. ex Miq. cultivar ‘Taezhny Dar’ and Actinidia kolomikta (Maxim. & Rupr.) Maxim. cultivar ‘Narodnaya’, was studied through energy dispersive spectrometry. The investigations were carried out during 2020 to 2021 at the Department of Genofonde and Bioresources of Plants, Federal Scientific Center for Horticulture, Moscow. The present research revealed that actinidia leaves contained the following major elements: K (11.19 mass% to 13.84 mass%), Ca (7.83% to 12.08 mass%), Cl (6.20 mass% to 7.33 mass%), and Mg (2.98 mass% to 3.44 mass%). Low values were recorded for Mo (1.19 mass% to 4.49 mass%) and P (0.83 mass% to 1.25 mass%). In both species, the mineral elements K and Ca were present at high levels. A positive correlation was observed between Mg–P, K–Mn, Mn–Se, Cu-Se, P–Si, Na–Mo, and Si–Mn in the leaves of A. argutа and between Cl–Ca, Mo; P–Si, Mo; and K–Ca in the leaves of A. kolomikta. Under stress conditions, the ratios of K/Ca and K/P declined to 0.9 and 6.3, respectively, whereas those of K/Cl, K/Mg, and K/Mo increased to 3.8, 4.4, and 2.7, respectively. The present studies conﬁrmed that actinidia leaves contained high concentrations of minerals, especially K, Ca, P, and Mg, and that the accumulation of mineral elements in actinidia plant leaves under drought conditions varied depending on the species.
