The present study was conducted to evaluate the effects of silicon (Si) and nano-silicon (NSi) on growth, yield, ions content, antioxidant defense systems, including transcript levels enzyme-encoding genes in Pisum sativum plants grown under salinity stress. Both Si NSi were applied at 3 mM level NaCl 4 concentrations (100, 150, 200 250 mM). Vegetative plant height, leaf area, fresh dry weights, yield attributes determined. Gene expression enzymes analyzed, their activities results showed...

Waste generation is a global issue that necessitates effective management for both human and animal health as well environment. There are several ways to reduce waste, but recycling appears be the best choice. By recycling, not only will problem of pollution resolved, valuable compounds could generated used nutrients plants. In this study, eco-friendly methods were established produce α- β-chitosan (CS) (as source nitrogen) with different degrees deacetylation from shrimp shells squid pin...

Abstract The current study aimed to detect the mutagenic impacts of aflatoxin B1 (AFB1), which is produced by Aspergillus group fungi, via a high-plant genotoxicity test. Different durations treatment (3 h, 6 and 12 h) were used treat Vicia faba root tips with varying concentrations Aflatoxin (AFB1) following approved protocol for plant assays published International Program on Chemical Safety (IPCS) World Health Organization (WHO). data obtained indicated that AFB1 not only has ability...

Green synthesis of nanoparticles is receiving more attention these days since it simple to use and prepare, uses fewer harsh chemicals chemical reactions, environmentally benign. A novel strategy aims recycle poisonous plant them as natural stabilizing capping agents for nanoparticles. In this investigation, silver loaded with latex from Cynanchum acutum L. (Cy-AgNPs) were examined using a transmission electron microscope, FT-IR spectroscopy, UV-visible spectroscopy. Additionally, Vicia faba...

Abstract Concerns about food security worldwide have been raised due to the adverse impacts of climate change on agricultural productivity. Utilizing wild relatives cultivated plants in breeding schemes is a potential solution address abovementioned challenges. Wild refer indigenous plant species that share genetic ancestry with recently plants. The capacity withstand abiotic stresses and enhance crop yield stability cold arid environments renders them valuable prospective resource for...

Aerva javanica is one of Egypt’s most important traditional medicinal plants used as antidiarrheal and anthelmintic medicine recently an anticancer agent. In this study, variations among ten populations in different sites the Eastern Desert Egypt were analyzed based on morphological ecological attributes molecular variation expressed by Inter-Simple Sequence Repeat (ISSR) markers. Morphological diversity was higher for Wadi El-Markh Bir Abbady regions than others. The polymorphism revealed...

There are three species of the genus Mesembryanthemum recorded in Egyptian flora (Mesembryanthemum crystallinum L., nodiflorum L. and forsskaolii Hochst. ex Bioss.). Various genetic markers (SDS-PAGE, RAPD ISSR) have been applied to evaluate variability structure within between twelve populations collected from different localities along International Coastal Road. The electrophoretic analysis protein was revealed 18 bands molecular weight ranging 11.6 104.6 KDa. Five generated 39 total...

Abstract The optimization of polymerase chain reaction (PCR) for random amplified polymorphic DNA (RAPD) analysis in Orobanche was investigated and the results were applied to O. aegyptiaca, oxyloba, ramosa three crenata collections gathered from different locations Egypt, Genotypes compared using 20 primers. polymorphisms detected only between tested species, while identical banding patterns generated same species. Genetic similarity among species estimated on basis percentage common bands...

The aim of the present study intended mainly to investigate interrelationships between six studied taxa namely Abutilon theophrasti, Lavatera cretica, Hibiscus trionum, sabdariffa, Malva parviflora and Sida alba collected from ten different accessions in Egypt belonging family Malvaceae. Biochemical studies include protein profile using SDS-PAGE technique three isozymes (esterase, peroxidase acid phosphatase). electrophoretic analysis revealed presence eighteen bands molecular weight ranging...

The present study conducted an experimental investigation to impede the degradation of peanut (Arachis hypogaea L.) seeds and enhance their quality while being stored. efficacy eco-friendly chemicals such as ascorbic acid, salicylic acetic propionic acid in seed preservation was evaluated over a period six months. After months storage greenhouse, examination on that had undergone treatment. Rhizoctonia observed after Cephalothorax, whereas Aspergillus, Fusarium, Penicillium were prevailing...

Achene morphs of Picris asplenoides L. and Urospermum picroides were investigated in order to gain insight into its genetic variation based on the evidence obtained from karyotype analysis, electrophoretic pattern achene proteins as well nucleic acid analysis. In L., three observed every inflorescence follows: violet, brown white, these differ their color. also color black. All diploid, with ten chromosomes somatic cells. Karyotype studies showed that have different formulae. However,...

Background and Objective: Biological control refers to purposeful utilization of introduced or resident living organisms other than disease resistant host.Antioxidants protect cells against the damaging effects reactive oxygen species otherwise called, free radicals such as singlet oxygen, super oxide, peroxyl radicals, hydroxyl peroxynite which results in oxidative stress leading cellular damage.Cytological abnormalities Vicia faba, studies are carried out root tips using this area...

Background and Objective: Genetic diversity of two Sesbania species (annual perennial) was studied via using different attributes karyotype formula, biochemical study (SDS-PAGE) molecular studies (RAPD ISSR markers).This focused on due to its medicinal importance from the previous literature.The objective paper is studying genetic conservation put light main difference between annual perennial one.Methodology: Seeds young leaves were collected ten locations in Egypt then seeds prepared into...

Background and Objectives: The aquatic macrophytes (hydrophytes) can be used as biological indicators in addition to physical chemical parameters for determining monitoring water quality.Hence, the main aim of this study were examine phytoremediation three types hydrophytes (floating, emergent submerged) investigate effect metals accumulation protein DNA these species.Methodology: Nine studied collected from two governorates El-Dakahlia Damietta Egypt spring 2017 follow: floating (Eichhornia...

Genetic diversity plays an important role in any long term management planning of a species. Mesembryanthemum crystallinum has been naturalized disturbed regions along the Mediterranean coast competing with native plants. The levels and pattern genetic variation within among its populations Deltaic Egypt was investigated using random amplified polymorphic DNA ( RAPD ). Forty‐two samples representing nine M. were collected. results showed that % PPB values for single population ranged from...
