The screening leaves showed positive results for a variety phytochemicals, alkaloids, tannins,...

Breeding high yielding water-deficit tolerant rice is considered a primary goal for achieving the objectives of sustainable development goals, 2030. However, evaluating performance pre-breeding-promising parental-lines water deficit tolerance prior to their incorporation in breeding program crucial success programs. The aim current investigation assess set pre-breeding lines compared with parents. To achieve this 7 along parents (5 genotypes) were field evaluated under well-irrigated and...

• Copper sulfate proved effective for eliminating endophytic bacteria in Philodendron selloum vitro cultures. Moderate level of copper did not induce growth abnormalities and was optimal shoot multiplication P. selloum. RAPD molecular marker revealed genetic fidelity the regenerated plantlets at all levels sulfate. Endophytic microorganisms is a major constrain to establishment tissue culture plants. We report use (CuSO 4 .5H 2 O) eliminate Contaminated shoots were cultured onto Murashige...

Gypsophila paniculata L. is one of the most important commercial cut flowers worldwide. The plant sterile and propagated mainly by in vitro culture techniques. However, hyperhydricity hinders its micropropagation increases mortality during ex acclimatization. Hyperhydric shoots G. were proliferated from nodal explants on MS medium without growth regulators that contained 30 g L-1 sucrose, gelled with 6.0 agar. Medium components environmental conditions optimized to revert microshoots develop...

The pollution of aquatic ecosystems is an issue facing many countries all over the world and may result in issues such as eutrophication coastal zones. Managing this a real challenge. current study focuses on investigation identification environmental characteristics, including sediments, waters, seaweed, seven eutrophicated locations along Mediterranean coast Alexandria (Egypt). Different ecological risk assessment bioaccumulation factors were calculated order to identify probable source...

Potentially toxic elements (PTEs)-induced genotoxicity on aquatic plants is still an open question. Herein, a single clone from population of water hyacinth covering large distribution area Nile River (freshwater) was transplanted in two drainage resources to explore the hazardous effect PTEs molecular, biochemical and anatomical characters compared those grown freshwater. Inductivity Coupled Plasma (ICP) analysis indicated that concentrations were relatively low most cases. However, high...

Microbial contamination is a common problem that causes significant losses in plant micropropagation systems. The present study reports on the identification and control of bacterial contaminants banana vitro cultures. Twelve isolates belonging to Bacillus pumilus (S2), subtilis (R2 M4), Geobacillus stearothermophilus (S1, S3, S4, P2, M3 R3) Paenibacillus spp. (P1, R1 M2) were identified by sequencing 16S rRNA, gyrA or gyrB genes. Antibiotic susceptibility testing was performed with disk...

Abstract Rice is the most important food crop for developing world. Hence, identifying rice genotypes to drought tolerance using as donors in breeding one of challenges research. Therefore, Molecular markers are useful tools determine genetic diversity and tolerance. In present study, A number 41 with different from geographic locations were evaluated by 15 SSR markers. total 68 alleles detected which 61(89.79%) polymorphic. The a single marker varied 2 8 an average 4.71 per locus....

In addition to the traditional breeding approaches, genetic variability in tomato can be induced also by means of mutagenesis. The objective this study was develop an vitro technique suitable for mutation induction on and characterize them RAPD SSR markers as well horticultural characteristics. influence various concentrations (0, 0.07, 0.14 0.25%) chemical mutagen, Ethyl Methane Sulfonate (EMS), shoot formation from cotyledon explants two cultivars studied. percentage responding ranged 45.2...

The present study was carried out for developing an efficient in vitro callus induction and plant regeneration system four different tomato genotypes ( Solanum lycopersicum Mill., previous name: Lycopersicon esculentum ), Advantage II, Edkawy, Castle Rock Super Strain B, using hypocotyl cotyledon explants. effects of two cytokinins, BA (benzyl adenine) Kin (kinetin), on frequency were investigated when added to MS medium combination at varying concentrations. All concentrations the...

This study aimed to evaluate the phytochemical components, antioxidant capacity, and antimicrobial effects of Diospyros villosa (L.) De Winter leaves stem bark. The extracts were obtained using different media (methanol, chloroform, hexane). DPPH FRAP methods used assess activity Folin–Ciocalteu method was determine total phenolic contents crude extracts. against five pathogenic bacteria determined MIC, MBC, agar-well diffusion methods. Flavonoids, alkaloids, phenols identified in D. mean...

A method for in vitro propagation through axillary shoot proliferation and induction of adventitious shoots as well Agrobacterium-mediated transformation Cordyline fruticosa is presented. In were cultured on MS medium supplemented 0–4 mg l− 1 thidiazuron (TDZ) their multiplication. with 0.1 TDZ proved to be the most effective which 14 per explants obtained. Leaf segments excised from (0–5 1) callus induction. Following induction, non-embryogenic calluses proliferated without plant growth...

ABSTRACT Gerbera (Gerbera jamesonii Bolus ex Hook. F.; Asteraceae), is one of the most economically important ornamental plants due to its aesthetic value. In present study, we established a micropropagation method for large-scale production quality planting material gerbera ‘Pink Melody’. Eighty-six percent capitulum explants produced adventitious shoots (15.44 ± 0.34 per capitulum) on Murashige and Skoogs (MS) medium containing 2 mg L−1 6-benzylaminopurine (BAP) after six weeks incubation....

Potato (Solanum tuberosum L.) is an economically important vegetable crop in Egypt. It the fourth most by volume of production; it high yielding, having a nutritive value and gives returns to farmers. Moreover, potato considered good source antioxidants (Chen et al., 2007). vegetatively propagated, heterozygous tetraploid, thus, traditional breeding very difficult (Solmon-Blackburn Baker, 2001). Biotechnology could be contributed solve this problem realize great benefit The regeneration...
