In this study, we have investigated the effect of copper oxide nanoparticles (CuO-NPs) on callogenesis and regeneration of Oryza sativa L (Super Basmati, Basmati 2000, Basmati 370, and Basmati 385). In this regard, CuO-NPs have been bio-synthesized via Azadirachta indica leaf extract. Scanning electron microscope (SEM) analysis depicts average particle size of 40 ± 5 nm with highly homogenous a...

Natural products are valuable and well known for their biological activities. In the current scenario, research analysis of plant leaf extract nanoparticles synthesis with activities has been expended significantly. For nanoparticles, Copper is preferred metal among other metals due to its reported use in medical field as antimicrobial agents lethality. The aim present work assess antioxidant m...

The objective of this study was to assess the structure, anti-tyrosinase activity, and mechanism of proanthocyanidins extracted from Rhododendron pulchrum leaves. Results obtained from mass spectra of matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) and high performance liquid chromatography electrospray ionization mass spectrometry (HPLC-ESI-MS) revea...

• In an effort to understand processes that are related to heavy metal sequestration, we characterized six metallothionein genes ( PtdMTs ) in the hybrid cottonwood, Populus trichocarpa × deltoides . • cDNA microarrays and reverse transcriptase-polymerase chain reaction were used to examine PtdMT expression in poplar tissues. They displayed differential gene expression patterns, which may be as...

The present study was undertaken for assessing the level of heavy metals such as copper, nickel and zinc in water, water hyacinth and soil samples of Rupahi beel, Nagaon, Assam. Metals were detected using flame atomic absorption spectrophotometry. The results revealed that by and large all the three metals are present in all the samples. The average concentration of Cu, Ni and Zn in both water ...

Dyeing properties of different fabric species were investigated using leaf extract Juglans regia L. For this purpose, the cotton and wool fabrics dyed brown napthaquinon colorant extracted from walnut leaves by pre-mordanting, meta-mordanting post-mordanting methods in presence copper sulfate (CuSO4.5H2O), ferrous (FeSO4.7H2O) alum (AIK(SO4)2.12H2O) at medium pH. Color codes determined with Pan...

Cotton leaf curl disease (CLCuD) is a severe disease of cotton that occurs in Africa and Pakistan/northwestern India. The disease is caused by begomoviruses in association with specific betasatellites that differ between Africa and Asia. During survey of symptomatic cotton in Sindh (southern Pakistan) Cotton leaf curl Gezira virus (CLCuGV), the begomovirus associated with CLCuD in Africa, was i...

The impact of organic feeding milk thistle on the intensity accumulation and factors in mass seeds lead, cadmium, zinc copper was studied. use fertilizers crop production is an important measure increasing volume improving its quality. However, also contributes to soil pollution with heavy metals, which can accumulate plants several tens times higher than soil. It known that such as humus defec...

Almond red leaf blotch is the most important fungal disease that is caused by the fungus Polystigma amygdalinum. Symptoms depending on the cultivar almond trees can be seen almost all year. In this study the effect of 5 fungicides (Copper oxychloride  2000 µg/ml, Bordofix 2000 µg/ml, Mancozeb 200 µg/ml, Bordo Compound 10000 µg/ml, Triforin 300 µg/ml with rep.control) was examined in a randomize...

Background & Aims of the Study: Aquatic macrophytes, given their rapid growth and high bio mass production, great potential to accumulate heavy metals in their organs. Phragmites australis as a hyper-cumulative plant plays an important role in the bioremediation. The Badavar River of Noorabad, Lorestan province, is exposed to urban wastewater and agricultural runoffs. In order to heavy metals (...
