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...

Survival biomass production and crop yield are heavily constrained by a wide range of environmental stresses. Several phytohormones among which abscisic acid (ABA), ethylene salicylic (SA) known to mediate plant responses these By contrast, the role hormone auxin in stress remains so far poorly studied. Auxin controls many aspects growth development, Response Factors play key transcriptional activation or repression auxin-responsive genes through direct binding their promoters. As mean gain...

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).

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...

The TomExpress platform was developed to provide the tomato research community with a browser and integrated web tools for public RNA-Seq data visualization mining. To avoid major biases that can result from use of different mapping statistical processing methods, raw sequence available in databases were mapped de novo on unique reference genome post-processed using same pipeline accurate parameters. Following calculation number counts per gene each sample, communal global normalization...

Lentil ( Lens culinaris Medikus) is a protein-rich cool-season food legume with an excellent source of protein, prebiotic carbohydrates, minerals, and vitamins. With climate change, heat, drought stresses have become more frequent intense in lentil growing areas strong influence on phenology, grain yield, nutritional quality. This study aimed to assess the impact heat quality lentil. For this purpose, 100 genotypes from global collection were evaluated under normal, combined heat-drought...

Microalgae are widely used in a variety of fields, including agriculture, the environment, medicine, cosmetics, food, and feed. They as feedstock for sustainably produced chemicals biofuel. However, production microalgal-derived products is economically unprofitable. Integrated biorefinery based on microalgae-derived one long-term solutions that could be environmentally viable with zero waste. This review emphasizes integration wastewater treatment CO2 biosequestration from industrial flue...

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...

High temperature and water deficit are among the major limitations reducing lentil (Lens culinaris Medik.) yield in many growing regions. In addition, increasing atmospheric vapor pressure (VPD) due to global warming causes a severe challenge by influencing balance of plants, thus also affecting growth yield. present study, we evaluated 20 genotypes under field conditions controlled environments with following objectives: (i) investigate impact stress combined temperature-drought on traits...

High temperature during the reproductive stage limits growth and development of lentil (Lens culinaris Medikus). The seed filling periods are most sensitive to heat stress, resulting in limited yield nutritional quality. Climate change causes frequent incidents stress for global food crop production. This study aimed assess impact high on grain yield, value, cooking Thirty-six genotypes were evaluated under controlled conditions their response. Genotypic variation was significant (p < 0.001)...

Lentil (Lens culinaris Medikus) is one of the most important cool season food legume crops grown in many countries. Seeds are typically rich protein, fiber, prebiotic carbohydrates and minerals, such as iron zinc. With changing climate variability, lentil crop faces frequent droughts heat stress varying intensity its major production zones. In present study, a set 162 accessions selected through Focused Identification Germplasm Strategy (FIGS) were screened for tolerance to combined...

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....

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...

Auxin response factors (ARFs) act as key elements of the auxin-signaling pathway and play important roles in process a plant's growth, development, to environmental conditions. We studied implication SlARF2 gene tomato salt (150 mM NaCl) drought (15% PEG 20000) stresses. The functional characterization knockdown mutants revealed that downregulation this enhanced primary root length branching reduced plant wilting. At physiological level, arf2 mutant line displayed higher chlorophyll, soluble...

ABSTRACT The root‐knot nematode Meloidogyne javanica is a significant pathogen that causes substantial yield losses in tomato plants. Moroccan farmers generally lack knowledge regarding the density of this pathogen, which can trigger visible and localised symptoms. Additionally, regional studies establish damage thresholds for issue are scarce. This study investigated threshold M. on plants using nine initial population densities (Pi) second‐stage juveniles (J2s): 0, 0.5, 1, 2, 4, 8, 16, 32...
