Abstract
The role of polymeric hydrogel (PMH) in wheat's response to Benzo[a]pyrene (BaP) stress is acknowledged, although mechanisms involved are not fully understood and have never reported. The present research found that exposure to BaP stress fast increased endogenous jasmonic acid levels in wheat roots. Polymeric hydrogel alleviated BaP toxicity by reducing BaP absorption in shoot cell walls and roots, accomplished through up-regulation of BaP chelation and efflux-associated genes like OsCAL1, OsABCG36 and OsHMA3, while concurrently down-regulating transcript degrees of BaP uptake and translocation-associated genes, such as OsZIP5/7, OsNRAMP1/5, OsCCX2 and OsHMA2. A decrease in hemicellulose levels was noted in cell wall of roots. The mitigating effect of polymeric hydrogel on BaP accumulation depended on the inhibition of nitric oxide production, as the nitric oxide donor SNP may diminish this effect. In brief, polymeric hydrogel significantly lowered BaP levels in wheat by downregulating cell wall's ability to absorb BaP, likely by decreasing nitric oxide generation.
期刊介绍：
Chemical and Biological Technologies in Agriculture is an international, interdisciplinary, peer-reviewed forum for the advancement and application to all fields of agriculture of modern chemical, biochemical and molecular technologies. The scope of this journal includes chemical and biochemical processes aimed to increase sustainable agricultural and food production, the evaluation of quality and origin of raw primary products and their transformation into foods and chemicals, as well as environmental monitoring and remediation. Of special interest are the effects of chemical and biochemical technologies, also at the nano and supramolecular scale, on the relationships between soil, plants, microorganisms and their environment, with the help of modern bioinformatics. Another special focus is the use of modern bioorganic and biological chemistry to develop new technologies for plant nutrition and bio-stimulation, advancement of biorefineries from biomasses, safe and traceable food products, carbon storage in soil and plants and restoration of contaminated soils to agriculture.
This journal presents the first opportunity to bring together researchers from a wide number of disciplines within the agricultural chemical and biological sciences, from both industry and academia. The principle aim of Chemical and Biological Technologies in Agriculture is to allow the exchange of the most advanced chemical and biochemical knowledge to develop technologies which address one of the most pressing challenges of our times - sustaining a growing world population.
Chemical and Biological Technologies in Agriculture publishes original research articles, short letters and invited reviews. Articles from scientists in industry, academia as well as private research institutes, non-governmental and environmental organizations are encouraged.
