Uniconazole can alleviate the growth inhibition and plant damage resulting from drought stress. In the current study, the effects of drought stress on the leaf physiology and yield of two potato varieties (Kexin No. 1, drought-tolerant, and Atlantic, drought-sensitive) and the ability of uniconazole to promote growth and productivity under drought conditions were studied. The results showed that uniconazole could effectively alleviate the degradation of chlorophyll under drought stress, and drought significantly inhibited the photosynthetic rate (<i>P</i>_n), transpiration rate (<i>T</i>_r), stomatal conductance (<i>G</i>_s), and intercellular CO₂ concentration (<i>C</i>_i) of the leaves of the two potato varieties. Exogenous uniconazole effectively alleviated the inhibitory effect of drought on the photosynthetic parameters of potato leaves. Compared with drought treatment, uniconazole treatment reduced malondialdehyde (MDA), hydrogen peroxide (H₂O₂) and superoxide anion (O₂⁻) production in the leaves of Kexin No. 1 and Atlantic plants and increased the activity of antioxidant enzymes, alleviating the loss of yield factors caused by drought stress. In addition, the antioxidant enzyme activity and nonenzymatic antioxidant activity of both varieties increased in response to drought stress. Drought + uniconazole treatment further increased the contents of the osmotic adjustment substances soluble protein and proline and ascorbate-glutathione (ASA-GSH) cycle products and substrates, including ascorbic acid (ASA), dehydroascorbate (DHA), glutathione (GSH) and oxidized glutathione (GSSG). Drought + uniconazole treatment also increased the ratio of ASA/DHA and GSH/GSSG in the two potato varieties under drought stress. This enhancement elevated the levels of reducing power and antioxidant capacity in the leaves, thus reducing the impacts of reactive oxygen species on the cell membrane. The drought-tolerant variety Kexin No. 1 exhibited a greater recovery than did the drought-sensitive variety Atlantic. These results provide a valuable reference for understanding the mechanism of drought resistance in potato plants and the effectiveness of uniconazole in alleviating drought-induced stress.</p>","PeriodicalId":13123,"journal":{"name":"Horticulture Environment and Biotechnology","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2024-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140300559","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study sought to understand the plant host response against GLR at the molecular level and select useful genes for the breeding of resistant grapes. Hence, transcriptome analysis was conducted in two pathogen-inoculated Korean wild grape genotypes, namely, <i>Vitis coignetiae</i> Pulliant (Vc) and <i>V. flexuosa</i> Thunb (Vf), resistant and susceptible to GLR, respectively. RNAs were extracted from uninfected and infected leaves 24 h post-inoculation (hpi). In transcriptome analysis, a total of differentially expressed genes (DEGs) were 3979 and 2436 in the resistant and susceptible genotypes, of which 1765 and 1162 were up-regulated, and 2214 and 1274 were down-regulated, respectively. The top five up-regulated genes in Vc compared to Vf were homolog of carrot EP3-3 chitinase, calcineurin B-like proteins (CBL)-interacting protein kinase 20 (CIPK20), chalcone and stilbene synthase family protein, osmotin 34, and major latex protein (MLP)-like protein 423 (MLP423). The five most down-regulated genes in Vc compared to Vf were RADIALIS (RAD)-like 1, flavonol synthase 1, glutamine synthetase 2, RAD-like 6, and GDSL-like lipase/acylhydrolase superfamily protein, which were validated for their expression by real-time PCR. According to the Gene Ontology (GO) analysis, most of the up-regulated genes in Vc were associated with metabolic processes, whereas, most of down-regulated genes in Vf were associated with catalytic activity. The down-regulated genes in Vc and up-regulated genes in Vf were mostly associated with metabolic processes and catalytic activity. Defense-related genes, including phenylalanine ammonia-lyase (PAL), pathogenesis-related (PR) proteins, and salicylic acid (SA)-dependent responses were differentially expressed against the infection by the pathogen.

Due to the abuse of phosphate fertilizer, acid rain has been frequently observed in recent years, resulting in the conversion of non-toxic aluminosilicates in the soil into Al ions, thereby causing stress to plants. As a DNA methylation inhibitor, curcumin can effectively counteract the Al stress on plants, while the epigenetic mechanism remains unclear. This study discusses the epigenetic mechanism of curcumin counteracting Al stress on grape. The results demonstrated that curcumin could significantly relieve the Al stress symptoms of grapes and reduce its whole genome methylation level. Al stress and curcumin treatment did not cause variations in the methylation level in each chromosome. While Al stress led to a slight increase in the average methylation level of each chromosome, and treatment by curcumin led to a significant decrease in the average methylation level of each chromosome. Specifically, the sites of CG and CHG were decreased significantly, and the site of CHH was increased or decreased significantly. Analysis of differentially-methylated regions (DMRs) revealed that treatment by curcumin led to an increase in hypo-DMRs in the whole genome of grape, and analysis of differentially-methylated genes (DMGs) also identified differentially related genes of hypo-DMRs in the whole genome of grapes, suggesting that curcumin triggers responses to Al stress by regulating hypo-methylation mode of the whole genome of grape.

The objective is to provide both theoretical insights and practical support to enhance berry quality and optimize wine fermentation processes. Eight treatments were established encompassing two main treatments (without urea and with urea application) and four sub-treatments (ferrous sulfate, ferrous gluconate, EDTA-Fe, and ferric citrate). Results indicate that the synergistic application of N fertilizer and chelated Fe fertilizer significantly improves the photosynthetic characteristics of grape leaves, leading to a remarkable enhancement in leaf chlorophyll content (13.7–83.9%). Moreover, the combined application of N and Fe fertilizers significantly boosts berry tannin levels (11.2–21.5%), anthocyanins (2.8–117%), and total phenols (1.9–41.2%). Additionally, there is a notable increase in the relative abundance of amino acids and flavonoids, contributing to an augmented yield (3.9–36.1%). Correlation analysis suggests that the synergistic application of N and Fe improves berry quality by augmenting N and Fe content in the leaves, promoting photosynthesis, improving water-use efficiency, and increasing leaf chlorophyll content. Overall, the comprehensive score of the principal component analysis reveals that the synergistic application of N fertilizer and chelated Fe fertilizer has the most significant effect, leading to substantial improvements in the quality and yield of the berries.

After UV-B irradiation, seedlings were moved to a greenhouse and exposed to ultraviolet rays of sunlight; growth was observed; and chlorophyll fluorescence was measured. When subjected to UV-B irradiation, minimal changes in external traits of fruit vegetable seedlings were observed at doses below 2.16 kJ·m⁻²·d⁻¹, while at higher intensities, issues such as chlorosis emerged. When UV-B was irradiated at 4.32 kJ·m⁻²·d⁻¹, cucumber exhibited a decrease in hypocotyl length by 6.4 cm, and watermelon by 1.7 cm compared with the control. Additionally, cucumber and watermelon both showed a decrease in leaf area by 75.6 cm² and 49.8 cm², respectively, indicating a tendency of growth inhibition.
