Secondary metabolites, such as phenols and salicylic, play a crucial role in the regulation of development tolerance mechanisms against wide range stresses. During adverse conditions biotic abiotic stresses, plants induce biosynthesis phenolic compounds to provide tolerance. Phenolics are secondary aromatic metabolites synthesized through shikimate/phenylpropanoid pathway or polyketide acetate/malonate pathway, which produce monomeric polymeric phenolics. Phenolic not only take part...

GABA counteracts wide range of stresses through regulation shunt pathway in plants. Although, assisted tolerance against As toxicity plants is still unexplored. We have examined induced rice seedlings with two exposure periods i.e., short term and long term. Results showed that accumulation reduced the expressions Lsi-1 Lsi-2 transporter genes, which ultimately decreased seedlings. The also modulated gene expression activity antioxidant enzymes, strongly Antioxidant enzymes such as CAT, POD,...

The study highlights the role of sulfur (S) in detoxification arsenate-induced toxicity and shift essential element homeostasis Zea mays L (SRHM 445). Overall growth arsenate-treated plants under starvation (−S) was lower than that presence excess (+S). Translocation arsenate from roots to shoots, increased As(−S) decreased with As(+S). level micronutrients (Cu, Zn, Fe) plants. Whereas, K PO4 higher As(+S) Higher malondialdehyde, protein carbonyl, H2O2 levels are indicative oxidative stress....

Ovarian cancer (OC) is the single most lethal gynecologic malignancy. Cannabis sativa used to treat various medical conditions, and cytotoxic a variety of types. We sought examine effectiveness different combinations cannabis compounds against OC. Cytotoxic activity was determined by XTT assay on HTB75 HTB161 cell lines. Apoptosis flow cytometry. Gene expression quantitative PCR protein localization confocal microscopy. The two active fractions, F5 F7, from high Δ9-tetrahydrocannabinol (THC)...

Abstract The present study evaluates the reduction of arsenate (As[V]) uptake in rice seedlings through individual and combined supplementation phosphate (PO 4 3– ) selenite (Se[IV]) a hydroponic condition. toxic response receiving As(V) manifested as inhibition physiological parameters such water use efficiency, stomatal conductance, photosynthetic assimilation rate, transpiration photochemical quenching, electron transport along with growth. Arsenic accumulation significantly decreased...

Abstract The level of peroxidase activity was greatly enhanced in tobacco leaves infected by necrosis virus (TNV) and other viruses which induce necrotic symptoms (TMV, ToMV PVY N ). intensity related to the age infected: absent or neglible mature very pronounced young growing leaves. On contrary, changes were negligible when infection provoked do not produce reactions (TMV O Analysis isoenzymes, pattern TNV necrosis‐inducing revealed all cases, a slight increase anionic (pl 3.5–3.7)...
