“…To determine the soluble sugar (SS) content, 0.1 g of shoot sections were added to 10 mL 80% ethanol, extracted in a water bath at 80 • C for 30 min, and then measured using the Anthrone-Sulfuric acid colorimetry method [31]. To determine the soluble protein (SP) content, 0.1 g shoot sections were ground into homogenate in precooled (4 • C) 0.1 mol/L phosphate buffer solution (PBS, pH = 7.8) and measured using the Coomassie brilliant blue G-250 method [32]. For enzyme activities detection, 3 g of shoot sections were added into 4 mL of precooled 50 mmol/L PBS (pH7.8), ground into homogenate, centrifuged at 10,000 rpm for 20 min to collect the supernatant, which was then used as crude enzyme solution for the determination of SOD, POD and CAT activity by using nitrogen blue tetrazole photoreduction method, guaiacol method and UV absorption method [33], respectively.…”

Cold stress occurs in late winter and early spring threatens greatly the nectarine industry. In this study, the semi-lethal low temperature (LT50) and thirteen cold resistance related parameters of five nectarine cultivars, including ‘Nonglehong little princess’ (LP), ‘Luyou No. 5’ (LY), ‘Nonglehong No. 6’ (NL), ‘Zhongyou No. 20’ (ZY) and ‘Qiuhongzhu’ (QH), were determined. Based on these parameters, they were categorized into high—(HR, including NL and LP), moderate—(MR, including QH) and low-cold resistant (LR, including ZY and LY) groups. The relative water (RW), proline (PRO), soluble sucrose (SS) and soluble protein (SP) contents, and superoxide dismutase (SOD) and peroxidase (POD) activities of HR cultivars were higher while their relative electronic conductivity (RE), malondialdehyde (MDA) and gibberellin acid (GA3) contents and catalase (CAT) activity were lower than other cultivars during natural overwintering. Redundancy analysis revealed that the lowest temperature in a day (LT) and LT50 significantly explains 69.8% and 10.9% of these physiological variables, respectively. Moreover, GA3 and indoleacetic acid (IAA) contents and CAT activity were positively correlated, while PRO, SS, ABA and RW contents were negatively correlated with both LT and LT50. Our study will be helpful in understanding the cold resistance variations of nectarine germplasm resources.

“…Applications of calcium (Ca 2+ ) in fruits contribute to the maintenance of firmness and cell turgor, reducing the incidence of diseases, and preventing physiological disorders (Jain et al, 2019). Additionally, calcium plays a crucial role in the expression of genes influencing fruit production and quality (Wu et al, 2023), as it stabilizes cell walls and ensures their permeability, protecting them from enzymatic degradation (Zhi et al, 2017). This regulation affects ripening in some fruits and influences respiration rates and ethylene production, thereby extending the quality of fruits during storage (Michailidis et al, 2020).…”

Calcium (Ca) plays a crucial role as a nutrient influencing the ripening, post-harvest duration, and quality of fruits. Its impact on the cell wall and its function as a secondary messenger at the cellular level underscore its significance. While recently there has been an increase in studies examining the effects of Ca on fruit quality, there remains a need to consolidate and expand the literature on pre-harvest and post-harvest applications of Ca concerning the physical-chemical properties of fruits. This review aims to compile information on the mechanisms of Ca absorption by plants, as well as the interaction of Ca with the cell wall in fruit development and growth; the review also aims to synthesize literature on the effects of calcium on the physical and chemical properties of fruits that ultimately influences their quality. The review considers a comprehensive analysis of studies published in reputable scientific publishers (Elsevier, Springer, Frontiers, Wiley, MDPI, Hindawi, SciELO) over the last ten years, encompassing various relevant topics. Calcium proves effective in retarding the loss of firmness in fruits, increasing their mass, mitigating mass loss during storage, and extending postharvest life, thereby enhancing marketability. Furthermore, Ca demonstrates a role in decreasing the activity of enzymes responsible for cell wall degradation. Additionally, it reduces ethylene production in fruits, delaying the climacteric peak and reducing its intensity. Its application results in delayed color changes in fruits. For soluble solids, Ca diminishes sugar values and postpones their peak during the post-harvest period while maintaining high total acidity values. Notably, Ca applications contribute to a decreased incidence of certain physiological disorders.

Foliar calcium application reduces fluorine accumulation in tea plant by regulating cell wall structure and gene expression

Tea plant can enrich a large amount of fluorine (F) in the cell wall of its mature leaves, thus posing the risk of excessive intake of F for tea consumers. This study investigated the effect of foliar calcium (Ca) application (0.05-1 mM) on F accumulation in tea plant leaves by analyzing the association of F with cell wall materials, pectin methylesterification structure, and cell wall genes. Ca spray could effectively reduce the F level, the content of wall carbohydrates (excluding the chelate pectin fraction) and the pectin methylesterification degree in tea plant leaves. Correlation analysis further revealed that the tea leaf F content was positively correlated with most of the cell wall materials. Transcriptomics analysis indicated that the key genes involved in reorganization of cell wall polysaccharides (such as CslE6, XTH32, PG, PGIP, PME18, PMEU1, and PMEI9) were associated with the variations in F content and cell wall components. All the results suggest that Ca may lessen the tea leaf F level by reducing the accumulation of cell wall materials and intervening the cell wall structure and gene expression. This study provided useful information for reducing the F level and solving the F safety problem in tea plant.
