Nanotechnology shows high promise in the improvement of agricultural productivity thus aiding future food security. In horticulture, maintaining quality as well limiting spoilage harvested fruit and vegetables is a very challenging task. Various kinds nanomaterials have shown potential for increasing productivity, enhancing shelf-life, reducing post-harvest damage improving horticultural crops. Antimicrobial nanofilm on products and/or packaging materials are suitable storage transportation...
Abstract Background Arsenic toxicity induces a range of metabolic responses in plants, including DNA methylation. The focus this paper was on the relationship between As-induced stress and plant senescence hyperaccumulator Pteris cretica var. Albo-lineata ( Pc -Al). We assume difference physiological parameters level methylation young old fronds as symptoms As toxicity. Results accumulation -Al fronds, grown pots haplic chernozem contaminated with 100 mg kg − 1 for 122 days, decreased age....
Nanomaterials (NMs) are emerging novel tools for preserving quality, enhancing shelf life, and ensuring food safety. Owing to the distinctive physicochemical characters, engineered NMs under varying sizes dimensions have great potentials application in manufacturing, packaging, processing, safety of quality agrifood. The promise various kinds that useful industries has opened a possibility new revolution agroprocessing both advanced nations. rapid advancement nanoscience provided impact on...
Many contaminated soils contain several toxic elements (TEs) in elevated contents, and plant–TE interactions can differ from single TE contamination. Therefore, this study investigated the impact of combined contamination (As, Cd, Pb, Zn) on physiological metabolic processes lettuce. After 45 days exposure, excess soil resulted inhibition root leaf biomass by 40 48%, respectively. Oxidative stress accumulation was indicated markers—malondialdehyde 5-methylcytosine—and visible symptoms...
Abstract In this study, we observed the effect of application soil dust enriched with risk elements (Cd, Pb, As and Zn) to leaf surfaces lettuce ( Lactuca sativa var. capitata ) while it was grown under hydroponic conditions. This study aimed determine how low particulate matter (PM) doses affected activity or damaged photosynthetic apparatus uptake associated both epigenetic changes (5-methylcytosine content, i.e., 5mC) stress metabolism. During obtained many results pertaining element...
Pollution and poisoning with carcinogenic arsenic (As) is of major concern globally. Interestingly, there are ferns that can naturally tolerate remarkably high As concentrations in soils while hyperaccumulating this metalloid their fronds. Besides Pteris vittata which As-related traits molecular determinants have been studied detail, the hyperaccumulation status has attributed also to cretica. We thus inspected two P. cretica cultivars, Parkerii Albo-lineata, for traits. The cultivars were...
The content of flavan-3-ol monomers and gallic acid in grape seeds the samples from gene collection Viticulture Research Station Karlstejn (Czech Republic) was investigated. Presence catechin, epicatechin, epigallocatechin, epicatechin gallate confirmed these samples, other like gallocatechin or epigallocatechin were below limit detection. As major catechin with 85 % detected. Average seed 4454 ± 148 µg·g-1, 3085 98 µg·g-1 600 41 457 19 acid, 352 16 gallate. Variety had main impact on...
Arsenic represents a serious health threat in localities with high arsenic-polluted environment and can easily get into the human food chain through agronomy production areas affected by arsenic contamination. Onion plants that were grown controlled conditions arsenic-contaminated soil (5, 10, 20 ppm) harvested 21 days after levels (from 0.43 ± 0.03 µg g-1 to 1761.11 101.84 g-1) onion samples roots low bulbs leaves, which is probably caused reduced ability of onions transport from leaves....
Experimental spinach plants grown in soil with (5, 10 and 20 ppm) arsenic (As) contamination were sampled 21 days after As(V) contamination. Levels of As samples (from 0.31 ± 0.06 µg g-1 to 302.69 11.83 g-1) higher roots lower leaves, which indicates a low ability translocate into leaves. Species arsenic, As(III) As(V), represented favor the (III) specie contaminated variants, suggesting enzymatic arsenate reduction. In relation predominant accumulation roots, changes malondialdehyde levels...
Zea mays L. plants were exposed to acetaminophen (APAP). Experiments conducted in an experimental greenhouse with semi-controlled conditions. Experimental grown concentrations of APAP 0, 200, 400, 600, 800, and 1000 mg L−1 for 14 days NFT hydroponic system. The impact contamination was observed on photosynthetic rate, water potential, proline content, levels 5-methylcytosine (5 mC%). results showed that the selected parameters influenced by different APAP. High caused a decrease...
Background: Grape marc and the wine cakes are known for high content of catechins, which have been reported to many beneficial effects human health. The most important on cardiovascular system. Also some potential combat Alzheimer´s disease has catechins contained in a green or white tea. Keywords: Alzheimer's disease, grape extract, prolyl oligopeptidase, oxidative stress, polyphenols.
Abstract Background: Arsenic toxicity induces a range of metabolic responses in plants, including DNA methylation. The focus this paper was on the relationship between As-induced stress and plant senescence hyperaccumulator Pteris cretica var. Albo-lineata ( Pc -Al). We assume difference physiological parameters level methylation young old fronds as symptoms As toxicity. Results: accumulation -Al fronds, grown pots haplic chernozem contaminated with 100 mg kg -1 for 122 days, decreased age....
Abstract Background Arsenic (As) toxicity induces a range of metabolic responses in plants, including DNA methylation. The focus this paper was on the relationship between As-induced long-term stress and plant senescence hyperaccumulator Pteris cretica var. Albo-lineata ( Pc -Al).Results We showed that -Al grown pots haplic chernozem contaminated with 100 mg As kg -1 (As ) for 122 days could accumulate more than 2000 2800 dry matter old young fronds, respectively.
