“…29 Soluble proteins in rice grains can be categorized into four distinct groups: albumin, globulin, glutelin, and prolamin. 18 HWs alone had a nonsignificant effect on the grain protein content (Figure 1d,e, Table S1). CeO 2 NPs induced a 9.0% reduction in globulin levels under ambient temperature conditions (Figure 1d).…”

The frequency, duration, and intensity of heat waves (HWs) within terrestrial ecosystems are increasing, posing potential risks to agricultural production. Cerium dioxide nanoparticles (CeO2 NPs) are garnering increasing attention in the field of agriculture because of their potential to enhance photosynthesis and improve stress tolerance. In the present study, CeO2 NPs decreased the grain yield, grain protein content, and amino acid content by 16.2, 23.9, and 10.4%, respectively, under HW conditions. Individually, neither the CeO2 NPs nor HWs alone negatively affected rice production or triggered stomatal closure. However, under HW conditions, CeO2 NPs decreased the stomatal conductance and net photosynthetic rate by 67.6 and 33.5%, respectively. Moreover, stomatal closure in the presence of HWs and CeO2 NPs triggered reactive oxygen species (ROS) accumulation (increased by 32.3–57.1%), resulting in chloroplast distortion and reduced photosystem II activity (decreased by 9.4–36.4%). Metabolic, transcriptomic, and quantitative real-time polymerase chain reaction (qRT-PCR) analyses revealed that, under HW conditions, CeO2 NPs activated a stomatal closure pathway mediated by abscisic acid (ABA) and ROS by regulating gene expression (PP2C, NCED4, HPCA1, and RBOHD were upregulated, while CYP707A and ALMT9 were downregulated) and metabolite levels (the content of γ-aminobutyric acid (GABA) increased while that of gallic acid decreased). These findings elucidate the mechanism underlying the yield and nutritional losses induced by stomatal closure in the presence of CeO2 NPs and HWs and thus highlight the potential threat posed by CeO2 NPs to rice production during HWs.

In the realm of the global economy, agriculture holds a prominent status, acting as a vital source of employment and revenue for nations. Despite its crucial role, the agricultural sector contends with recurrent annual losses attributable to market fluctuations. One noteworthy contributor to the decline in agricultural productivity is the adverse impact of microplastics (MPs). This study aims to estimate the production losses suffered by key crops—rice, wheat, maize, tomato, and peas—due to MPs, along with the resulting economic consequences arising from the direct damage inflicted by MPs. To assess production losses caused by MPs, secondary data from diverse sources were employed for five plant varieties. The economic losses resulting from MPs were calculated for the period spanning 2017–2023, with cumulative data aggregated from all states. The study's findings indicate that the presence of MPs corresponds to an annual global output decline ranging from 0.4% to 34.7%. This decline translates to a reduction of approximately 0.01 million to 66.97 million tons per year in the production of food, fiber, and biofuels. The aggregate yearly economic losses are estimated at around USD 46.5 billion. These findings carry substantial implications for governmental policy in the agricultural domain, underscoring the necessity for current statistics on global losses incurred due to MPs. Moreover, they emphasize the importance of implementing a systematic surveillance system to monitor such losses effectively.
