The current study sought to determine the effects of Colpomenia sinuosa and Sargassum linifolium aqueous extracts on non-enzymatic and enzymatic antioxidants in Spinacia oleracea L. leaf extract. Glutathione synthase (GSS, EC: 6.3.2.3) and -glutamyl cysteine synthetase (-GCS, EC: 6.3.2.2) are involved in the glutathione biosynthesis process. Treatment of S. oleracea with seaweed extracts increased the level of reduced glutathione (GSH), oxidized glutathione (GSSG), and total glutathione at lower concentrations. Total phenols and total flavonoids in S. oleracea leaves accumulated more rapidly after treatment with seaweed extracts. The activity of the enzyme’s phenylalanine ammonia lyase (PAL, EC: 4.3.1.25), chalcone synthase (CHS, EC: 2.3. 1.74), and chalcone isomerase (CHI, EC: 5.5.1.6) involved in the production of phenylpropanoid and flavonoid in S. oleracea leaves rose in a dose-dependent manner. Glutathione reductase (GR, EC 1.6.4.2), glutathione peroxidase (GPX, EC: 1.11.1.9), and glutathione-S-transferase

Background: The Zucchini yellow mosaic virus (ZYMV) is well recognized as a very significant viral pathogen that causes substantial yield reductions in cucurbitaceous crops on a global scale. Methods: To detect and identify ZYMV in squash plants we used the serology reaction, transmission electron microscope, and molecular methods. Results: ZYMV was first isolated from naturally infected squash plants in the Alexandria governorate of Egypt, where it caused mosaic, yellowing, and deformation of the leaves. In addition to a molecular diagnosis utilizing RT-PCR, the identification relied on serological responses with antisera to CMV, SqMV, and ZYMV. Using centrifugation and PEG, the virus was cleaned. The A260/280 and A280/260 ratios of the purified virus were 1.38 and 0.72, respectively, which are consistent with those of a nucleoprotein. 2.36 mg of pure virus was recovered from per 100g of infected leaf material. The virus particles, as seen under an electron microscope after a partial purification preparation technique, have a flexuous filamentous structure and measure around 750 nm in length and 12 nm in diameter. Finally, the molecular investigation established the identification of the ZYMV isolate after a specific antiserum with a titer of 1:2.56×10 4 was generated and tested at the third week.
