Role of zinc in management of plant diseases: A review

Cogent Food & Agriculture, Journal Year: 2023, Volume and Issue: 9(1)

Published: March 27, 2023

Management of disease by using agrochemicals has possessed serious issues and threats to food safety environment due excess use. The management diseases enhancing resistance or tolerance through plant nutrition contributes as well sustainable integrated management. Further, these nutrients optimize yield. Utilization in requires the knowledge their association with defence mechanisms. This review describes Zinc (Zn) developing a plant's mechanism reducing severity diseases. It was found that Zn plays an important role functioning enzymes/proteins like alcohol dehydrogenase, superoxide dismutases, metallothionein zinc-finger proteins involved plants' response pathogens. supply increases expression various antioxidant systems detoxifying harmful level free radicals upon infection. enhances signalling pathways salicylic acid-dependent jasmonic acid/ethylene-dependent improves membrane integrity assisting against pathogens' attack. A deficiency makes susceptible infection deprived condition while negatively impacts growth toxicity. Thus, high non-toxic levels can be beneficial responses which depend on nature its interaction study provides basis for exploration negative relationship between nutrient

Zinc and nano zinc mediated alleviation of heavy metals and metalloids in plants: an overview

Functional Plant Biology, Journal Year: 2023, Volume and Issue: 50(11), P. 870 - 888

Published: Aug. 20, 2023

Heavy metals and metalloids (HMs) contamination in the environment has heightened recently due to increasing global concern for food safety human livability. Zinc (Zn2+ ) is an important nutrient required normal development of plants. It essential cofactor vital enzymes involved various biological mechanisms Interestingly, Zn2+ additional role detoxification HMs plants its unique biochemical-mediating several soil plant processes. During any exposure high levels HMs, application would confer greater resilience by decreasing oxidative stress, maintaining uptake nutrients, photosynthesis productivity optimising osmolytes concentration. also ameliorating toxicity regulating metal through expression certain transporter genes, targeted chelation translocation from roots shoots. This review examined roles nano Zn described their involvement alleviating Moving forward, a broad understanding uptake, transport, signalling tolerance /zinc nanoparticles will be first step towards wider incorporation into agricultural practices.

Zinc Oxide Nanoparticles Affect Early Seedlings’ Growth and Polar Metabolite Profiles of Pea (Pisum sativum L.) and Wheat (Triticum aestivum L.)

International Journal of Molecular Sciences, Journal Year: 2023, Volume and Issue: 24(19), P. 14992 - 14992

The growing interest in the use of zinc oxide nanoparticles (ZnO NPs) agriculture creates a risk soil contamination with ZnO NPs, which can lead to phytotoxic effects on germinating seeds and seedlings. In present study, susceptibility seeds/seedlings pea wheat NPs various sizes (≤50 ≤100 nm) applied at concentrations range 100–1000 mg/L was compared. Changes metabolic profiles seedlings were analyzed by GC GC-MS methods. size-dependent harmful effect seedling’s growth revealed. more toxic (50 lowest concentration (100 mg/L) caused 2-fold decrease length roots. peas, root elongation slowed down 20–30% only 1000 NPs. response common for all tested cultivars wheat, significant increase sucrose (in roots shoots) GABA roots). seedlings, an increased content metabolites involved aspartate–glutamate pathway TCA cycle (citrate, malate) found, while total amino acids tissues) malate roots) decreased. Moreover, products starch hydrolysis (maltose glucose) endosperm indicates disturbances mobilization.
