Nanotechnology has demonstrated significant potential to improve agricultural production and increase crop tolerance abiotic stress including exposure heavy metals. The present study investigated the mechanisms by which aloe vera extract gel-biosynthesized (AVGE) selenium nanoparticles (Se NPs) alleviated cadmium (Cd)-induced toxicity rice (Oryza sativa L.). AVGE Se NPs, chemically synthesized bare NaSeO3 as an ionic control were applied Cd-stressed seedlings via root in both hydroponic soil systems. Upon NPs at 15 mg Se/L, fresh biomass was significantly increased 100.7% 19.5% compared Cd conventional NPs. Transcriptional analyses highlighted that activated signaling defense related pathways, glutathione metabolism, phenylpropanoid biosynthesis plant hormone signal transduction. Specifically, upregulated expression of genes associated with gibberellic acid (GA) 4.79- 3.29-fold Cd-alone treatment untreated control, respectively. Importantly, restored composition endophyte community recruit beneficial species under exposure; relative abundance Azospirillum roots, shoots, rhizosphere 0.73-, 4.58- 0.37-fold, respectively, treatment. Collectively, these findings highlight enhance growth minimize Cd-induced provide a promising nanoenabled strategy food safety upon cultivation contaminated soils.

Cadmium is considered a highly toxic metallic element that does not have any beneficial biological functions for humans or plants. It has been reported the antagonism of selenium to heavy metal stress observed in variety plants, and appropriate could alleviate heavy-metal-induced oxidative damage reduce accumulation metals Changes physiological characteristics, root tip cells, cadmium concentration, rape under were investigated this study through pot experiment. Results showed inhibitory effect on growth seedlings. The concentration decreased after application seeds, ranging from 19.93 22.97% 27.96 43.88%, respectively, decrease photosynthetic pigment content induced by was significantly improved. results transmission electron microscopy exogenous had complexation reaction formed black precipitation, which may be related detoxification cadmium. More critically, with addition selenium, plasma membrane free radical tips gradually alleviated histochemical staining experiment tips. These provide evidence exploring effective measures cadmium-contaminated areas.
