Comparative Analysis of Organic Extracts Bioactivity from Two Limonium. Mill Species Growing Wild in Tunisian Salty Marshes.

Limonium. Mill is a genus of flowering plants belonging to the Plumbaginaceae family. The present study aimed to compare two Limonium species (L.

The Phytochemical Screening and Biological Properties of L. var. (Rutabaga) Seeds.

Rutabaga, also known as swede and scientifically classified as , is a biennial edible root vegetable that belongs to the genus and is widely cultivated in North Europe and North America. The present study highlights both the phytochemical profile and the in vitro biological properties of rutabaga seed extracts obtained through maceration using solvents of increasing polarity, namely, cyclohexane (CYHA), dichloromethane (DCM), ethyl acetate (EtOAc), methanol (MeOH), and water (HO). HPLC-DAD was used to identify and quantify phenolic compounds, while volatile compounds were detected using GC-MS.

Genus Seeds: A Review on Phytochemical Screening and Pharmacological Properties.

Traditionally, species are widely used in traditional medicine, human food, and animal feed. Recently, special attention has been dedicated to seeds as source of health-promoting phytochemicals. This review provides a summary of recent research on the seed phytochemistry, bioactivity, dietary importance, and toxicity by screening the major online scientific database sources and papers published in recent decades by Elsevier, Springer, and John Wiley.

Geographical location and cultivar-linked changes on chemical properties of olive oils from Algeria.

In the present work, we are assessing the geographical origin and cultivar-related changes on olive oil quality and composition in East Algeria. Fruits from the main local olive varieties (Sigoise and Chemlal) were harvested in autumn 2019 growing season from three different geographic areas: semiarid (Setif), arid (Batna), and Saharan (Eloued). Obtained results showed that Chemlal and Sigoise olive oils from Eloued area were the most enriched in tocopherols and phenolic contents, respectively.

Assessment of the risks of copper- and zinc oxide-based nanoparticles used in Vigna radiata L. culture on food quality, human nutrition and health.

The present article aims to assess the phytotoxic effects of copper and zinc oxide nanoparticles (Cu NPs, ZnO NPs) on mung bean (Vigna radiata L.) and their possible risk on food quality and safety. We also study the molecular mechanisms underlying the toxicity of nanosized Cu and ZnO.

African mustard (Brassica tournefortii) as source of nutrients and nutraceuticals properties.

Brassica tournefortii is an annual herbaceous plant, native to the North Africa and Middle East. It is considered as an excellent medicinal plant due to its richness by antioxidant like isothiocyanates and polyphenols. The present study is the first phytochemical investigation on Brassica tournefortii organs (leaves, stems, and roots) in terms of nutraceutical, chemical composition, and bioactivity.

Evaluation of Antioxidant Status of Two Limoniastrum Species Growing Wild in Tunisian Salty Lands.

We aim to highlight the differential antioxidant status of Limoniastrum guyonianum and Limoniastrum monopetalum in relation to their respective chemical and location characteristics. Metabolite analysis revealed similar contents in phenolic, flavonoïds, sugars and chlorophyll in the two species' leaves. Higher amounts of proline (Pro), carotenoïds (Carot), sodium (Na) and potassium (K) were measured in L.

Expression pattern of genes encoding nitrate and ammonium assimilating enzymes in Arabidopsis thaliana exposed to short term NaCl stress.

Key steps in nitrate nutrition and assimilation were assessed over two weeks in control and 100mM NaCl-exposed Arabidopsis thaliana (Columbia) plants. The data showed that NaCl stress lowered nitrate contents in both leaves and roots. While NaCl stress decreased ammonium contents in leaves, it increased the contents in roots at the end of treatment.

Ion uptake and structural modifications induced by nitrogen source in tomato (Solanum lycopersicum Mill. Cv. Ibiza F1).

Interactions between NO(3)(-) and NO(2)(-) were studied at the level of root uptake, ion translocation (NO(3)(-), NO(2)(-), K(+)), ion xylem exudates composition and inorganic cation contents (K(+), Ca(2+), Mg(2+)) using tomato seedling (Solanum lycopersicum Mill cv. Ibiza F1). Nitrite was supplied in the medium as KNO(2) (0, 0.

An Arabidopsis mutant disrupted in ASN2 encoding asparagine synthetase 2 exhibits low salt stress tolerance.

Salt tolerance of Arabidopsis knockout mutant with T-DNA insertion in ASN2 gene encoding asparagine synthetase (AS, EC 6.3.5.

Tissue-specific cadmium accumulation and its effects on nitrogen metabolism in tobacco (Nicotiana tabaccum, Bureley v. Fb9).

Tobacco (Nicotiana Tabaccum, Bureley v. Fb9) seedlings were grown for 30 days on control medium, and then treated for seven days with different concentrations (0, 10, 20, 50 and 100 muM) of CdCl(2). Cadmium (Cd) was mostly accumulated in the leaves.

Changes in growth and activity of enzymes involved in nitrate reduction and ammonium assimilation in tomato seedlings in response to NaCl stress.

Background And Aims: In Tunisia, salt water is largely used for tomato irrigation. In this work, a study was made of the changes in the nitrate reduction and ammonium assimilation into amino acids in tomato seedlings under salinity in order to providee further insight into the salt effects on plant growth. Methods Ten-day-old tomatoes (Solanum lycopersicum) were subjected to 100 mm NaCl stress, and nitrogen metabolism in leaves and roots was studied.

NaCl stress effects on enzymes involved in nitrogen assimilation pathway in tomato "Lycopersicon esculentum" seedlings.

Tomato plants (Lycopersicon esculentum Mill, cv. Chibli F1) grown for 10 days on control medium were exposed to differing concentrations of NaCl (0, 25, 50, and 100mM). Increasing salinity led to a decrease of dry weight (DW) production and protein contents in the leaves and roots.
