The use of actinomycetes for improving soil fertility and plant production is an attractive strategy developing sustainable agricultural systems due to their effectiveness, eco-friendliness, low cost. Out 17 species isolated from the rhizosphere legume crops, 4 bioactive isolates were selected impact on 5 legumes: soybean, kidney bean, chickpea, lentil, pea evaluated. According morphological molecular identification, these belong genus Streptomyces. Here, we showed that increased nutrients...

Marrubium vulgare is a valuable source of natural bioactive molecules with high preventive and therapeutic effectiveness. Therefore, this study aimed to the chemical polymorphism populations M. in Tunisia by quantitative markers estimation divergence between populations. Phytochemical analyses eight Tunisian prospected different bioclimatic stages, revealed 42 compounds essential oils representing 96.08% 100% total oil. Hydrocarbon sesquiterpenes were main fraction all studied β-bisabolene...
Soil contamination with indium (In) oxide nanoparticles (In2O3-NPs) threatens plant growth and development. However, their toxicity in plants under ambient (aCO2) elevated (eCO2) conditions is scarcely studied. To this end, study was conducted to investigate In2O3-NPs the young old leaves of C3 (barley) C4 (maize) understand mechanisms underlying stress mitigating impact eCO2. Treatment significantly reduced photosynthesis, induced oxidative damage (H2O2, lipid peroxidation), impaired P Fe...
SiNPs orchestrate carbon and nitrogen metabolism cell fortification in pea seedlings to cope with<italic>Phelipanche</italic>infection.
Soil contamination with indium oxide nanoparticles (In2O3-NPs) is a challenge for plant growth and productivity. Despite In2O3-NPs toxicity, their effects on metabolism are largely unknown, particularly under future climate CO2 (eCO2). Therefore, the toxicity stress mitigating impact of eCO2 in young old leaves C3 (wheat) C4 (sorghum) plants were investigated. Overall, significantly retard biomass photosynthetic machinery all tested crops, plants. Consequently, altered C N On other hand,...
The biochemical responses of tomato ( Lycopersicon esculentum Mill.) roots to different concentrations the hormonal elicitors, salicylic acid (SA) and indole acetic (IAA), as presoaking treatments, on healthy Orobanche ramosa -infected plants were studied in pot experiment under control conditions. Application SA IAA activate production proline soluble proteins roots, where their levels more pronounced infected than plants. Moreover, both elicitors increased phenolics flavonoids accompanied...
The present work was conducted to evaluate the effect of aqueous extract Alhagi maurorum at different rates (1, 5, 10, 15%, w/v) on growth as well some physiological parameters pea (Pisum sativum L.). pot experiment revealed that reduced all plant along with photosynthesis pigments, insoluble sugars, total carbohydrate, protein and phenolics. On other hand, soluble protein, proline, flavonoids antioxidant enzymes increased upon treatment solution maurorum. adverse treated plants especially...
The use of plant growth-promoting bacteria (PGPB) to enhance growth and protection against heavy metal toxicity has been extensively studied. However, its potentiality reduce arsenate toxicity, a threat metabolism, hardly investigated. Moreover, the toxic effect arsenic oxide nanoparticles (As-NPs) on plants possible mechanisms for alleviation not yet explored. In this study, impact bioactive actinomycete Streptomyces spp. growth, physiology stress-related metabolites, such as sugars...
Vanadium (V) can be beneficial or toxic to plant growth and the interaction between arbuscular mycorrhizal fungi (AMF) V stress was rarely investigated at physiological biochemical levels of groups (C3 C4) organs (roots shoots). We tested potential AMF alleviate negative effects (350 mg V/Kg soil) on shoots roots rye sorghum. Relative sorghum (C4), (C3) showed higher lower key elements under conditions. inhibited growth, photosynthesis, induced photorespiration (increased HDR & GO...
Drought stress is one of the most important factors limiting survival and growth plants in different habitats Egypt. This study was carried out to investigate effect drought on some metabolic activities sunflower seedlings under treatments with ascorbic acid (AsA) or CaCl2. showed a marked reduction shoot length, leaf area, fresh dry weight, photosynthetic pigments, soluble sugar, amylase activity. On other hand, root proteins, protease activity, proline content, phenolics flavonoid...
Invasive field weeds, such as Euphorbia sp., represent main threat for crop productivity. The present work was conducted to evaluate the phytotoxicity of helioscopia on wheat (Triticum aestivum L.) and pea (Pisum sativum L.). influence aqueous extract from shoot E. helioscopia, at different rates (1.0%, 2.5%, 5.0%, 10.0%; w/v), germination early seedling growth well some synchronized physiological aspects investigated. severely affected in a concentration dependent manner. Plumule radicle...
Antimony (Sb), a common rare heavy metal, is naturally present in soils at low concentrations. However, it increasingly used industrial applications, which turn, leads to an increased release into the environment, exerting detrimental impact on plant growth. Thus, important study Sb effects plants under current and future CO2 (eCO2).To this end, high concentrations (1500 mg/kg soil) ambient (420 ppm) eCO2 (710 wheat growth, physiology (photosynthesis reactions) biochemistry (minerals...
