Appraisal of the physiological response of cakile maritima and brassica juncea ...
Bouslimi, Houda; Didri, Nesrine; Brito, Pedro; Caçador, Isabel; Hidouri, Saida; Sleimi, Noomene; Ferreira, RenataRare earth elements were extensively employed for many years to improve plant growth in farming. However, their effect on plant’s behavior relies on their concentration and the plant species. The impact of low doses of lanthanum (La; 1–10 μM) on plant growth, mineral uptake, and the production of secondary metabolites was assessed in two Brassicaceae species (Cakile maritime and Brassica juncea) after 14 days o...
Comparison of digestion methods using atomic absorption spectrometry for the de...
Bankaji, Insaf; Kouki, Rim; Dridi, Nesrine; Hidouri, Saida; Duarte, Bernardo; Sleimi, Noomene; Caçador, Isabel; Ferreira, RenataTrace metal elements (TMEs) are among the most important types of pollutants in the environment. Therefore, a precise determination of these contaminants in several environmental components is required for the safety assurance of living organisms. Spectroscopic analysis is an efficient technique employed to detect and determine TME contents in numerous samples. Hence, to achieve reliable and accurate results wh...
Photosythetic responses of two salt-tolerant plants, Tamarix gallica and Arthro...
Sghaier, Dhouha Belhaj; Pedro, Sílvia; Duarte, Bernardo; Caçador, Isabel; Sleimi, NoomeneIn recent years, the level of arsenic in soil has increased dramatically in many countries, which has raised concern to develop new environmentally friendly techniques to solve problems such as arsenic, which is highly soluble and has toxic effects. It is an environmental issue and a global health matter because of its poisonous and carcinogenic characteristics. It is known that arsenic influenced farmland and ...
Physiological and Biochemical behaviours and antioxidant response of Helianthus...
Dridi, Brito, P. N. H.; Bouslimi, Ferreira, R.; Martins-Dias, Caçador, I. S.; Sleimi, NoomeneThe continuous progress of global manufacturing and anthropogenic activities has resulted in excessive environmental metallic pollution, particularly with rare earth elements (REEs) which have become a prevalent issue of global concern due to their high toxicity and widespread existence. REEs-contaminated soils could ruin agriculture by inducing plant physiology disturbances in various crops that are considered...
Assessment of tolerance to Lanthanum and Cerium in Helianthus Annuus Plant: Eff...
Dridi, Nesrine; Bouslimi, Houda; Brito, Pedro; Martins-Dias, Susete; Caçador, Isabel; Sleimi, Noomene; Ferreira, RenataRare earth elements (REEs) present a group of nonessential metals for the growth and development of plants. At high concentrations, they can induce internal stress and disturb the physiological and biochemical mechanisms in plants. The potential uptake of lanthanum (La) and cerium (Ce) by the horticultural plant Helianthus annuus and the effect of these elements on its growth, its absorption of macroelements, a...
Behavior of Cucumis sativus L. in presence of aluminum stress: Germination, pla...
Kouki, Rim; Ayachi, Rim; Sleimi, Noomene; Ferreira, RenataAluminum (Al) is an ubiquitously present element in soil; it is considered as a major problem in crop production that affects plant growth and development on acid soils. The aim of this work was to determine the germination parameters, to quantify the water status and growth, to assess the Al accumulation, and antioxidant enzyme activities in plants to evaluate the stress exerted by aluminum in Cucumis sativus ...
Functional and ecophysiological traits of Halimione portulacoides and Sarcocorn...
Duarte, Bernardo; Silva, Helena; Dias, João Miguel; Sleimi, Noomene; Marques, J. C.; Caçador, IsabelThe present paper aims to discuss the functional and ecophysiological traits of two abundant succulent halophytes in Mediterranean salt marsh systems, considering two ecotypes differing on their tidal exposure. In Halimione portulacoides the higher root/shoot (R/S) biomass ratio verified in low inundation frequency (LF) marshes, as compared with that in high inundation frequency (HF), indicates an optimal parti...
Tissue Localization and Distribution of As and Al in the Halophyte Tamarix gall...
Sghaier, Dhouha Belhaj; Pedro, Silvia; Diniz, Mário Sousa; Duarte, Bernardo; Caçador, Isabel; Sleimi, NoomeneInformation on localization of Al and As in Tamarix gallica is required in order to better understand the detoxification mechanisms that confer tolerance in this halophyte plant species. Plants were subjected to different Al and As concentrations with and without salt supplementation. High concentrations of As and Al have been found in Tamarix gallica leaves and roots without symptoms of toxicity to the plant, ...
Assessing of tolerance to metallic and saline stresses in the halophyte Suaeda ...
Bankaji, Insaf; Caçador, Isabel; Sleimi, NoomeneMany areas are simultaneously affected by high concentrations of salts and trace metal elements (TME), the latter constituting a serious threat to human health. In the present study, we determined the combined effect of high salinity and toxic levels of trace elements on physiological behavior of the halophytic species Suaeda fruticosa. Plants were cultivated for three months with an irrigation solution supplem...
Biophysical and Biochemical Markers of Metal/Metalloid-Impacts in Salt Marsh Ha...
Anjum, Naser A.; Duarte, Bernardo; Caçador, Isabel; Sleimi, Noomene; Duarte, Armando C.; Pereira, EduardaAs a major sink, estuarine/salt marsh ecosystem can receive discharges laden with myriads of contaminants including metals/metalloids from man-made activities. Two among the major consequences of metal/metalloid-exposure in estuarine/salt marsh ecosystem flora such as halophytic plants are: (a) the excessive accumulation of light energy that in turn leads to severe impairments in the photosystem II (PS II), and...
