    Abstract This worked aimed to test the hypothesis that L-alanyl-L-glutamine (Ala-Gln) improves the varicocele-induced testicular injury, which causes male infertility. For this purpose, fifty adult male Wistar rats received the varicocele (VC) surgery at the left renal vein. Biomarkers were determined 2, 4, and 8 weeks after VC (n = 10/each detection). Four weeks after VC, rats received Ala-Gln (1.125 g/kg) treatment with and or saline for 1 week (n = 10/each group). Rats in the sham group were also detected for biomarkers at 2, 4, and 8 weeks (n = 10/each detection). VC caused testicular injury detected by hematoxylin–eosin (H&E)… More >

    Hesham F. Alharby1, Mirza Hasanuzzaman2,*, Hassan S. Al-Zahrani1, Khalid Rehman Hakeem1

    Phyton-International Journal of Experimental Botany, Vol.90, No.2, pp. 373-388, 2021, DOI:10.32604/phyton.2021.013657

    Abstract The mechanism of selenium (Se)-induced salt tolerance was studied in moderately sensitive soybean (Glycine max L.) plants. To execute this view, soybean plants were imposed with salt stress (EC 6 dS m−1 ) applying NaCl. In other treatments, Se (0, 25, 50 and 75 µM Na2SeO4) was sprayed as co-application with that level of salt stress. Plant height, stem diameter, leaf area, SPAD value decreased noticeably under salt stress. Altered proline (Pro) level, together with decreased leaf relative water content (RWC) was observed in salt-affected plants. Salt stress resulted in brutal oxidative damage and increased the content of H2O2, MDA… More >

    Abstract Drought is the most common form of abiotic stress that reduces plant growth and productivity. It causes plant injuries through elevated production of reactive oxygen species (ROS). Potassium (K) is a vital plant nutrient that notably ameliorates the detrimental effect of drought stress in the plant. A pot experiment was conducted at the Laboratory of Plant Stress Responses, Faculty of Agriculture, Kagawa University, Japan, under controlled environment of green house to explore the role of K in mitigating drought severity in wheat (Triticum asevitum L.) seedlings. Three days after germination, seedlings were exposed to three water regimes viz., 100, 50,… More >

    Abstract The cell activity of adipose-derived stem cells (ADSCs) is affected by the intracellular reactive oxygen species (ROS) and the level of autophagy. Previous studies reveal that acetyl-L-carnitine (ALC) possesses capacities of resisting oxidative stress and regulating autophagy. Activating molecule in Beclin1-regulated autophagy protein 1 (AMBRA1) plays a key role in initiating Beclin1-regulated autophagy. In the present study, we discovered ALC pretreatment (1 mM, 24 h) significantly increased the activity of ADSCs exposed to H2O2 (100 μM, 2 h) in vitro with improved stemness, and reduced the production of intracellular ROS. In addition, we found for the first time that ALC… More >

    Abstract The current study investigated the comparative oxidative damage in two maize seedlings induced by saline, drought, and combined stress and the ameliorative role of two different doses (20 and 80 µM) of 5-aminolevulinic acid (ALA) against the above-mentioned stresses. Hydroponically grown 10-day-old maize (Zea mays, var. BARI Hybrid Maize-7 (BHM-7) and BARI Hybrid Maize-9 (BHM-9)) seedlings were exposed to 12 dS/m of saline solution, 200 mM mannitol-induced drought stress alone and their combined stress for 7 days. Result revealed that individual stresses retard the plant growth to some degrees; however, their combined stress has more detrimental effects, which might be… More >

    Abstract

    Chemical composition of the bark extracts of Coula edulis was investigated to find potential antioxidant, anti-termite and antifungal compounds which can find useful applications in the fields of food, nutraceuticals, cosmetics or agrochemical. Phytochemical screening revealed the presence of several groups of active molecules such as alkaloids, polyphenols, flavonoids, saponins and sterols and/or terpenes in the different extracts. Total phenols, condensed tannins and flavonoids contents corroborated phytochemical screening. Gas chromatography-mass spectrometry (GC-MS) analysis revealed compounds in dichloromethane extract different from those obtained with all the other solvents. Hexadecanoic and trans-9-octadecenoic acids, as well as stigmasterol and β-sitosterol have been identified… More >

    Kai Sheng1, Saichao Wei1, Jun Mei1,2,3,4,*, Jing Xie1,2,3,4,*

    Phyton-International Journal of Experimental Botany, Vol.90, No.1, pp. 291-305, 2021, DOI:10.32604/phyton.2020.012985

    Abstract Low-temperature storage is extensively used to optimize the postharvest life of various fresh fruits. However, red pitahaya (Hylocereus polyrhizus) fruits are sensitive to chilling injury (CI), which leads to the limitation of low-temperature storage. In this study, red pitahaya fruits were stored at 2, 4, 6, 8, and 10°C, respectively, for 27 days to determine the appropriate storage temperature. During the storage of red pitahaya fruits, storage at 8°C was more effective in suppressing decay and maintaining quality than other low temperatures. Low-temperature (2, 4, and 6°C) storage decreased weight loss (WL) and maintained higher content of titratable acidity (TA),… More >

    Houda Bouslimi1, Renata Ferreira2, Nesrine Dridi1, Pedro Brito3, Susete Martins-Dias4, Isabel Caçador5, Noomene Sleimi1,*

    Phyton-International Journal of Experimental Botany, Vol.90, No.1, pp. 145-158, 2021, DOI:10.32604/phyton.2020.011752

    Abstract Soil contamination by toxic trace metal elements, like barium (Ba), may stimulate various undesirable changes in the metabolic activity of plants. The plant responses are fast and with, direct or indirect, generation of reactive oxygen species (ROS). To cope with the stress imposed by the ROS production, plants developed a dual cellular system composed of enzymatic and non-enzymatic players that convert ROS, and their by-products, into stable nontoxic molecules. To assess the Ba stress response of two Brassicaceae species (Brassica juncea, a glycophyte, and Cakile maritime, a halophyte), plants were exposure to different Ba concentrations (0, 100, 200, 300 and… More >

    Phyton-International Journal of Experimental Botany, Vol.89, No.4, pp. 943-955, 2020, DOI:10.32604/phyton.2020.013801

    Abstract Manganese (Mn) is one of the essential microelements in all organisms. However, high level of Mn is deleterious to plants. In this study, the effects of exogenous manganese application on mineral element, polyamine (PA) and antioxidant accumulation, as well as polyamine metabolic and antioxidant enzyme activities, were investigated in Malus robusta Rehd., a widely grown apple rootstock. High level of Mn treatments decreased endogenous Mg, Na, K and Ca contents, but increased Zn content, in a Mn-concentration-dependent manner. Polyamine metabolic assays revealed that, except the content of perchloric acid insoluble bound (PIS-bound) spermine, which increased significantly, the contents of putrescine… More >

    Abstract Drought is one of the major abiotic stresses that affect plant growth and reduce agricultural productivity. Use of algal extract as a biostimulant is gaining increased attention from researchers. This study aimed to investigate the potential of Ulva prolifera extract (UE) as a biostimulant when enzymatically extracted under conditions of water deficit. UE treatments (0.02%, 0.06%, and 0.1%) significantly improved the shoot length, root length, and dry weight of roots after 120 h of drought stress relative to that in treatment with the negative control. An increase in catalase (CAT) and peroxidase (POD) activity was also observed that resulted in… More >
