Durum wheat is the 10th most important crop in world, and its use traces back to origin of agriculture. Unfortunately, last century only part genetic diversity available for this species has been captured modern varieties through breeding. Here, population structure shared among elites landraces collected from 32 countries was investigated. A total 370 entries were genotyped with Axiom 35K array identify 8,173 segregating single nucleotide polymorphisms (SNPs). Of these, 500 selected as...
Durum wheat ( Triticum durum Desf.) is a major cereal crop grown globally, but its production often hindered by droughts. Breeding for adapted root system architecture should provide strategic solution better capturing moisture. The aim of this research was to adapt low‐cost and high‐throughput methods phenotyping exploring the genetic variability among 25 genotypes. Two protocols were used: “clear pot” seminal “pasta strainer” evaluate mature roots. Analysis variance revealed significant...
The aim of this work was to test Lupinus luteus plants, inoculated with metal resistant rhizobacteria, in order phytostabilise metals contaminated soils. resistance heavy strains isolated from nodules plants evaluated. strain MSMC541 showed multi-resistance several (up 13.3 mM As, 2.2 Cd, 2.3 Cu, 9 Pb and 30 Zn), it selected for further characterization. Furthermore, able biosorb great amounts cell biomass. 16S rDNA sequencing positioned within the genus Serratia. presence arsenic genes...
Ulvan, carrageenan, alginate and laminarin were tested in olive trees' twigs to elicit phenolic metabolism control verticillium wilt of (VWO) caused by Verticillium dahliae. The elicitation effect was determined through phenylalanine ammonia-lyase activity, total polyphenol content lignin content. VWO assessed previously elicited (24 h) maintained a solution containing bio-elicitors (2 g/L) conidial suspension (106 conidia/mL). Our results showed stimulation the decline symptoms. Ulvan...
The BRAFV600E oncogene, reported in 40%-60% of papillary thyroid cancer (PTC), has an important role the pathogenesis PTC. It is associated with loss iodide-metabolizing genes, such as sodium/iodide symporter (NIS), and therefore radioiodine refractoriness. Inhibition mitogen-activated protein kinase (MAPK) pathway, constitutively activated by BRAFV600E, not always efficient resistant tumors suggesting that other compensatory mechanisms contribute to a adaptive resistance. Recent studies...
The objective of this study was to understand and characterize the physiological biochemical tolerance mechanisms Argania spinosa under drought stress for selection tolerant ecotypes. Significant differences were observed among ecotypes in indices leaf water status studied: stomatal conductance (gs), predawn potential (Ψpd) relative content. There a significant decrease these traits with increasing degree all Drought significantly increased endogenous H2O2 lipid peroxidation. Moderate severe...
The exploitation of phosphate mines generates an important quantity sludge that remains accumulated and not valorized. In this context, composting with organic matter rhizospheric microorganisms offers interesting alternative is more sustainable for agriculture. This work aims to investigate the synergetic effect arbuscular mycorrhizal fungi (AMF), phosphate-solubilizing bacteria (PSB) phospho-compost (PC), produced from phosphate-laundered wastes, their combination on plant growth,...
Abstract Drought and desertification are the major environmental constraints facing Sahelian agro-ecosystems for decades. Assessing genetic diversity of native tree species is critical to assist ecosystems restoration efforts. Here we describe structure seven Balanites aegyptiaca L . natural populations distributed across Sahelian-Saharan zone Mauritania using 16 polymorphic ISSR primers. These generated 505 bands. Polymorphism information content (PIC) varied from (0.13–0.29) with an...
Verticillium wilt of olive (VWO), caused by dahliae (Vd), represents a significant threat to cultivation, particularly the Moroccan cultivar “Picholine Marocaine”, reducing yield, tree survival, and overall productivity. Current chemical cultural control strategies provide limited efficacy, highlighting need for alternative approaches such as biological control. This study investigated potential Rhizophagus irregularis (RI) agent mitigate VWO over 10-month period following V. inoculation....
Forty rhizobia nodulating four Acacia species (A. gummifera, A. raddiana, cyanophylla, and horrida) were isolated from different sites in Morocco. These compared by analyzing both the 16S rRNA gene (rDNA) 16S-23S spacer PCR with restriction fragment length polymorphism (RFLP) analysis. Analysis of showed a considerable diversity within these microsymbionts, but RFLP analysis amplified revealed no additional heterogeneity. Three clusters identified when rDNA was carried out. Two include some...
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...
Nitrogen fixing bacteria isolated from hot arid areas in Asia, Africa and America but diverse leguminous plants have been recently identified as belonging to a possible new species of Ensifer (Sinorhizobium). In this study, 6 strains clade were compared with at the genome-wide level. Their capacities utilize various carbon sources establish symbiotic interaction several examined. Draft genomes selected Morocco (Merzouga desert), Mexico (Baja California) well India (Thar desert) produced....

An experiment conducted on four contrasting ecotypes Argania spinosa plants: two coastal (Admine (Adm) Rabia (Rab)) inland (Aoulouz (Alz) Lakhssas (Lks)). Drought stress significantly decreased leaf potential stomatal conductance contrasted ecotypes. In terms biochemical responses,...
Durum wheat (Triticum durum Desf.) breeders over the past century have increased productivity and resilience of this crop via strong selection applied to genes controlling agronomically important traits. Along process, some primitive genetic diversity species was lost. A debate exists on whether or not original should be re-introgress into modern germplasm in order facilitate new improvements. Here, possible negative effects re-introducing were assessed by comparing performances three ICARDA...
Heat stress occurring during the reproductive stage of wheat has a detrimental effect on productivity. A durum core set was exposed to simulated terminal heat by applying plastic tunnels at time flowering over two seasons. Mean grain yield reduced 54% compared control conditions, and number most critical trait for tolerance this stress. The combined use indices identified five top performing elite lines: Kunmiki, Berghouata1, Margherita2, IDON37-141, Ourgh. also subjected genome wide...
