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...
Impact of Elevated Atmospheric CO2 in Spartina maritima Rhizosphere Extracellul...
Duarte, Bernardo; Baeta, Alexandra; Marques, João Carlos; Caçador, IsabelAtmospheric CO2 enrichment, which is caused to a large extent by anthropogenic activities, is known to interfere with sediment microbial communities via plant rhizospheres. The present work aimed to evaluate this interaction in Spartina maritima ((Curtis) Fernald.) rhizosediments, aiming to depict the impacts of atmospheric CO2 increase in the biogeochemical processes occurring in the rhizosphere of this pionee...
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...
Cistus ladanifer metal uptake and physiological performance in biochar amended ...
Duarte, Bernardo; Pires, Vanessa; Carreiras, João; Carvalho, Ricardo Cruz de; Pereira, Manuel F.C.; Maurício, António M.; Martins-Dias, SuseteBiochar amendments are known to have a considerable influence on phytoremediation processes. Considering this, in the present work, we aimed to evaluate the effect of biochar amendments in metal-contaminated mine soils focusing on the metal uptake by Cistus ladanifer and its physiological consequences. Plants were exposed to mine soils with different biochar supplementations and the plant's physiological perfor...
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 ...
Soilless cultivated halophyte plants: volatile, nutritional, phytochemical, and...
Oliveira-Alves, Sheila C.; Andrade, Fábio; Sousa, João; Bento-Silva, Andreia; Duarte, Bernardo; Caçador, Isabel; Salazar, Miguel; Mecha, ElsaThe use of halophyte plants appears as a potential solution for degraded soil, food safety, freshwater scarcity, and coastal area utilization. These plants have been considered an alternative crop soilless agriculture for sustainable use of natural resources. There are few studies carried out with cultivated halophytes using a soilless cultivation system (SCS) that report their nutraceutical value, as well as t...
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...
Effect Biomarkers of the Widespread Antimicrobial Triclosan in a Marine Model D...
Duarte, Bernardo; Feijão, Eduardo; Cruz De Carvalho, Ricardo; Matos, Ana Rita; Cabrita, Maria Teresa; Novais, Sara C.; Moutinho, ArianaThe present-day COVID-19 pandemic has led to the increasing daily use of antimicrobials worldwide. Triclosan is a manmade disinfectant chemical used in several consumer healthcare products, and thus frequently detected in surface waters. In the present work, we aimed to evaluate the effect of triclosan on diatom cell photophysiology, fatty acid profiles, and oxidative stress biomarkers, using the diatom Phaeoda...
Fluoxetine induces photochemistry-derived oxidative stress on Ulva lactuca
Feijão, Eduardo; Carvalho, Ricardo Cruz de; Duarte, Irina A.; Matos, Ana Rita; Cabrita, Maria Teresa; Utkin, Andrei B.; Caçador, IsabelEmerging pollutants impose a high degree of stress on marine ecosystems, compromising valuable resources, the planet and human health. Pharmaceutical residues often reachmarine ecosystems, and their input is directly related to human activities. Fluoxetine is an antidepressant, and one of the most prescribed selective serotonin reuptake inhibitors globally and has been detected in aquatic ecosystems in concentr...
