Lead (Pb) is one of the most widespread heavy metal contaminant in soils. It highly toxic to living organisms. Pb has no biological function but can cause morphological, physiological, and biochemical dysfunctions plants. Plants have developed a wide range tolerance mechanisms that are activated response exposure. affects plants primarily through their root systems. Plant roots rapidly respond either (i) by synthesis deposition callose, creating barrier stops entering (ii) uptake large...
Auxin controls multiple aspects of plant growth and development. However, its role in stress responses remains poorly understood. acts on the transcriptional regulation target genes, mainly through Response Factors (ARF). This study focuses involvement SlARF4 tomato tolerance to salinity osmotic stress. Using a reverse genetic approach, we found that antisense down-regulation promotes root development density, increases soluble sugars content maintains chlorophyll at high levels under...
Screening of native plant species from mining sites can lead to identify suitable plants for phytoremediation approaches. In this study, we assayed heavy metals tolerance and accumulation in dominant growing on abandoned Pb/Zn site eastern Morocco. Soil samples were collected analyzed As, Cd, Cu, Ni, Sb, Pb, Zn concentrations. Bioconcentration factor (BCF), translocation (TF), biological coefficient (BAC) determined each element. Our results showed that soils present low organic matter...
Lead is a heavy metal of particular concern with respect to environmental quality and health. The lack plant species that accumulate tolerate Pb limiting factor understand the molecular mechanisms involved in tolerance. In this study we identified Hirschfeldia incana, Brassicaceae collected from metalliferous mine spoils Morocco, as accumulator plant. H. incana exhibited high accumulation soils hydroponic cultures. Major occurred roots part translocated shoots, even siliques. These findings...
Hirschfeldia incana, a pseudometallophyte belonging to the Brassicaceae family and widespread in Mediterranean region, was selected for its ability grow on soils contaminated by lead (Pb) .The global comparison of gene expression using microarrays between plant susceptible Pb (Arabidopsis thaliana) tolerant (Hirschfeldia incana) enabled identification set specific genes expressed response exposure. Three groups were particularly over-represented exposure biological processes categorized as...
This study aims to assess the level of metal contamination and ecological risk index at abandoned Zaida Pb/Zn mining site in eastern Morocco identify native plant species found on that can be used rehabilitation through phytoremediation strategies. Samples from seven abundant site, along with their rhizospheric soils, were collected analyzed using Inductively Coupled Plasma Mass Spectrometry (ICP-MS) determine concentrations various metal(loid)s, including As, Cu, Ni, Cd, Sb, Zn, Pb....
Abstract Heavy metal contamination is of particular concern for human health and the environment. Phytoremediation an emerging cost‐effective strategy to remediate heavy contaminated soil. However, this technique limited by small number plants that are tolerant metals also accumulators. This study assayed zinc, lead, cadmium tolerance accumulation in Cistus libanotis, albidus , salviifolius . The were cultivated hydroponic conditions exposed different concentrations Pb(NO 3 ) 2 (100 200 µM),...
Abstract The present work undertaken in the environmental context aims to study distribution of heavy metals plants that grow naturally around uncontrolled landfills. study's goal was identify can be used remediate contaminated soils. For this purpose, 14 species and their rhizospheric soil samples were collected analyzed for arsenic, cadmium, cobalt, chromium, copper, lead, nickel, zinc by inductively coupled plasma‐atomic emission spectrometry. results showed presence elevated metal...

Background: Argan (Argania spinosa) is an important arid species in Morocco, hence the need to undertake nursery practices that promote its regeneration and sustainability a vulnerable environment. This study aimed examine effect of container size growing medium on morphological traits, biomass, as well root morphology one-year-old argan seedlings Marrakech region Morocco. Methods: Three sizes 300, 400, 500 cm3 were selected which seven types media with varying proportions acacia compost,...
Peganum harmala L., commonly known as Harmal, is an aromatic and medicinal plant that grows in North Africa. P a pseudometallophyte occur both heavy metals contaminated non soils . In order to identify the best adapted suitable populations within P. species, comprehensive analysis evaluation of morphological, physiological, biochemical responses lead (Pb) zinc (Zn) were performed three metallicolous (MP) non-metallicolous one (NMP). Zaida, Mibladen, Aouli Morrocan sites, growing show low...
