“…This study found that K signi cantly, negatively and directly affected nobiletin and tangeretin, which may due to K has impacts on the carbohydrate metabolism process in primary metabolism, such as the activation of key enzyme activities (Oosterhuis et reported that application of calcium fertilizer mainly regulates the occurrence of grape fruit cracking by regulating the content of secondary metabolites related to avonoid biosynthesis pathway genes. This study indicated that Ca mainly signi cantly, negatively and directly affected hesperidin, of which the physiological mechanism may be originated from interaction between synthesis of anthocyanins and expression of avonoid pathway genes, as well as calcium, as a cell second messenger (Kour et al 2023), participates in the regulation of intracellular enzyme activity. Magnesium (Mg) is involved in photosynthesis, glycolysis, phosphorylation of tricarboxylic acid cycle, enzyme catalysis and transport of metabolites (Li et which may interpret the indirect effect of Mg owing to the direct impact of K on nobiletin and tangeretin, and Ca on hesperidin.…”

Aims Environmental conditions, such as soil stress, are crucial for the accumulation of secondary metabolites in medicinal plants. This study aims to determine which soil type and environmental factors can promote the accumulation of hesperidin, nobiletin and tangeretin in the pericarps of Citrus reticulata ‘Chachi’ (Citrus reticulata cv. Chachiensis).Methods This study selected Citrus reticulata ‘Chachi’ planted in paddy soil, red soil, alluvial soil and conducted correlation between meteorological, soil factors and the three components. Then, linear regression models (LRMs) and random forest models (RFMs) were used to screen the soil factors affecting accumulation of the three components. Structural equation models (SEMs) were established to further explore how key soil factors affect the accumulation of the three components.Results Our results indicated that there was no significant difference in meteorological factors among the three regions (p > 0.05), and no correlation was found between the meteorological factors and the three components. Soil factors in three soil types, such as K, Ca, Mg, Mn, salinity and pH, have significant impacts on the content variation of hesperidin, nobiletin and tangeretin. The deficiency of K and Ca, play a crucial role in the accumulation of the three components.Conclusions Citrus reticulata ‘Chachi’ cultivated in soil with deficient K and Ca is more inclined to accumulate hesperidin, nobiletin and tangeretin in pericarps, which provides guidance for reasonable cultivation and paddy, red and alluvial soil improvement to promote the contents of medicinal components and the quality of medicinal plants.

“…Ca 2+ helps maintain the structural integrity of cells and prevents them from collapsing or being damaged under water stress conditions. Additionally, Ca 2+ can improve cellular turgor or maintain proper cellular turgor even under severe deficit irrigation conditions contributing to cell survival and normal functioning ( Ahanger et al., 2013 ; Kour et al., 2023 ). In our study, a higher concentration of Ca 2+ in leaves could assume the same roles as indicated above in the SW and MW treatments (especially in SW).…”

Soil water deficit and salinity represent a major factor impacting plant survival and agricultural production. The frequency and severity of both abiotic stresses are expected to increase in a context of climate change, especially in arid and semi-arid regions. This work studied the growth pattern, biomass and mineral distribution and the seasonal pattern of water status, photosynthetic rate and stomatal conductance in plant of Pistacia lentiscus grown under different levels of water deficit and salinity. P. lentiscus plants growing under greenhouse conditions were subjected to four irrigation treatments during 11 months: control (C, 1 dS m-1), moderate water deficit (MW, 1dS m-1, 60% of the control), severe water deficit (SW, 1 dS m-1, 40% of the control) and saline (S, 4dS m-1). The results show that Pistacia lentiscus plants were more affected by deficit irrigation than salinity. Deficit irrigation and salinity inhibited plant height, with reductions of 20%, 22% and 35% for S, MW and SW, respectively. Total leaf area was not modified by effect of the treatments, with the result that plant compactness increased in MW. The salt stressed plants only showed lower relative growth rate at the end of the experiment. Plants responded to saline or drought stress by increasing their osmotic adjustment, which was more pronounced under salinity. Saline plants had the highest values in Na+ and Cl- ions and the lowest values for K+/Na+ and Ca2+/Na+ ratios in leaves and stems, which is correlated with a decrease in growth, stomatal conductance, photosynthesis and stem water potential, and can be used as a diagnostic tool to assess plant tolerance to salinity stress. As a measure of plant hydration, relative water content was more sensitive to deficit irrigation than salinity, being a good indicator of water stress. P. lentiscus plants subjected to both deficit irrigation treatments exhibited an increase in their intrinsic water use efficiency, which is an important adaptation for plants growing in environments with water scarcity.

“…Elevated intracellular calcium can activate calcium-dependent signaling pathways, including those that control gene expression involved in various pathological conditions. Calcium functions as a secondary messenger in a variety of signaling pathways [ 130 ] and calcium signaling pathways have the ability to join on transcription factors that are involved in the transcriptional control of genes, including RAGE, such as CREB (cAMP Response Element-Binding) [ 131 ]. ChIP assay (Chromatin Immunoprecipitation assay) identifies target genes that are directly controlled by RAGE in inflammation by establishing a correlation between RAGE binding to particular genomic areas and changes in gene expression levels.…”

The review delves into the methods for the quantitative assessment of intracellular effectors and cellular response of Receptor for Advanced Glycation End products (RAGE), a vital transmembrane receptor involved in a range of physiological and pathological processes. RAGE bind to Advanced Glycation End products (AGEs) and other ligands, which in turn activate diverse downstream signaling pathways that impact cellular responses such as inflammation, oxidative stress, and immune reactions. The review article discusses the intracellular signaling pathways activated by RAGE followed by differential activation of RAGE signaling across various diseases. This will ultimately guide researchers in developing targeted and effective interventions for diseases associated with RAGE activation. Further, we have discussed how PCR, western blotting, and microscopic examination of various molecules involved in downstream signaling can be leveraged to monitor, diagnose, and explore diseases involving proteins with unique post-translational modifications. This review article underscores the pressing need for advancements in molecular approaches for disease detection and management involving RAGE.
