In Mesembryanthemum crystallinum, crassulacean acid metabolism (CAM) is seemingly reversible, but unequivocal evidence for functional CAM withdrawal has yet to be shown. In this study, we confirmed the rapid downregulation of PEPC1 expression just 1 h after the removal of NaCl from the plant growth

Exogenously applied H2O2 (50, 100 and 200mM) to Mesembryanthemum crystallinum root medium induced a transition from C3 to Crassulacean Acid Metabolism (CAM), as evaluated by diurnal malate (Δmal) fluctuations. A very high concentration of H2O2 (400mM) reduced Δmal below the value measured in control

The metabolic switch from C3-photosynthesis to crassulacean acid metabolism (CAM),and the antioxidative response of Mesembryanthemum crystallinum L. plants cultured under severe salt stress and high light intensities, and a combination of both stress conditions, were studied. High light conditions

The implication of enzymatic and non-enzymatic antioxidative systems in response to Ni was evaluated in the halophyte Mesembryanthemum crystallinum in comparison with the metal tolerant glycophyte species Brassica juncea. Seedlings of both species were hydroponically subjected during

Cosmetic or pharmaceutical composition containing superoxide dismutase (SOD) was usually used in topical administration, particularly, in fighting against skin ageing and in the protection of the skin against radiation exposure. Mesembryanthemum crystallinum is a halophyte plant widely used in the

Halophyte ability to withstand salt-triggered oxidative stress is governed by multiple biochemical mechanisms that facilitate retention and/or acquisition of water, protect chloroplast functioning, and maintain ion homeostasis. Most essential traits include the synthesis of osmolytes, specific

Thirteen species of wild edible plants belonging to 11 botanical families consumed in the traditional Mediterranean diet were evaluated. Sanguisorba minor, Quercus ballota and Sedum sediforme showed the highest hydrophilic total antioxidant activity (H-TAA) and total phenols. Asparagus acutifolius,

Organic wastes were successfully used as soil amendment to improve agrosystems productivity. Yet, the effectiveness of this practice to enhance plant antioxidant capacities has received little attention. Here, we assess the effect of municipal solid waste (MSW) compost (at 40 t ha(-1)) on growth,

Callus was obtained from hypocotyls of Mesembryanthemum crystallinum seedlings cultured on two types of medium-germination medium (GM) and callus induction medium (CIM). Following subculture on shoot induction medium SIM1, the callus formed on CIM medium regenerated roots or somatic embryos, while

Mesembryathemum crystallinum plants performing C(3) or CAM (crassulacean acid metabolism) appear to be highly resistant to Botrytis cinerea as well as to Pseudomonas syringae. Fungal hyphae growth was restricted to 48h post-inoculation (hpi) in both metabolic types and morphology of hyphae differed

In the present study, shoot extracts from edible halophytic Mesembryanthemum species were evaluated for their effects against O(2)(-), DPPH, and ABTS radicals. The reducing power, chelating ability, inhibition of lipid peroxidation and of beta-carotene bleaching were also evaluated. Moreover, the

Mesembryanthemum edule L. is an edible and medicinal halophyte widespread in Tunisia seashore. In this study, parameters of oxidative stress, phenolic compounds and antioxidant activities were comparatively investigated in two M. edule provenances (Jerba and Bizerte, respectively sampled from arid

CONCLUSIONS H2O2 is necessary to elicit rhizogenic action of auxin. Activities of specific catalase and manganese superoxide dismutase forms mark roots development. Hypocotyl explants of Mesembryanthemum crystallinum regenerated roots on medium containing 2,4-dichlorophenoxyacetic acid. Explants

Mechanical wounding of Mesembryanthemum crystallinum leaves in planta induced a fast decrease in stomatal conductance, which was related to accumulation of hydrogen peroxide (H(2)O(2)). Higher levels of H(2)O(2) were accompanied by an increase in total activity of superoxide dismutase (SOD) and a

A naturally occurring BHT was identified in the leaves of the halophyte plant Mesembryanthemum crystallinum. This phenol was extracted in this study by two methods at the different plant growth stages. One of the methods was better for BHT extraction; the concentration of this phenol is plant growth
