“…As stress produces excessive reactive oxygen species (ROS), reactive nitrogen species (RNS) and free radicals, among others, which destroy the structures of organelles, damage DNA and RNA and interfere with physiological and biochemical processes, such as carbohydrate, protein and nucleic acid metabolism, and thus, inhibit the growth and development of rice. This results in a decrease in biomass, rate of seed setting, yield and reduction in quality [ 17 ] ( Figure 1 ).…”

“…As(III) is the dominant form and is absorbed primarily by rice in flooded paddy soil [ 31 ]. Since As(III) is an analog of boric acid and silicic acid [ 17 ], it is currently reported that As(III) is absorbed by the transmembrane transport of some subfamily members of the major intrinsic protein (MIP) family ( Table 1 ), such as nodulin26-like intrinsic proteins (NIPs), plasma membrane intrinsic proteins (PIPs) and tonoplast intrinsic proteins (TIPs) [ 32 ]. Among these, the aquaporins NIPs are particularly important.…”

Rice (Oryza sativa L.) is the staple food for more than 50% of the world’s population. Owing to its growth characteristics, rice has more than 10-fold the ability to enrich the carcinogen arsenic (As) than other crops, which seriously affects world food security. The consumption of rice is one of the primary ways for humans to intake As, and it endangers human health. Effective measures to control As pollution need to be studied and promoted. Currently, there have been many studies on reducing the accumulation of As in rice. They are generally divided into agronomic practices and biotechnological approaches, but simultaneously, the problem of using the same measures to obtain the opposite results may be due to the different species of As or soil environments. There is a lack of systematic discussion on measures to reduce As in rice based on its mechanism of action. Therefore, an in-depth understanding of the molecular mechanism of the accumulation of As in rice could result in accurate measures to reduce the content of As based on local conditions. Different species of As have different toxicity and metabolic pathways. This review comprehensively summarizes and reviews the molecular mechanisms of toxicity, absorption, transport and redistribution of different species of As in rice in recent years, and the agronomic measures to effectively reduce the accumulation of As in rice and the genetic resources that can be used to breed for rice that only accumulates low levels of As. The goal of this review is to provide theoretical support for the prevention and control of As pollution in rice, facilitate the creation of new types of germplasm aiming to develop without arsenic accumulation or within an acceptable limit to prevent the health consequences associated with heavy metal As as described here.

“…Como exemplo, o selênio (Se) atua diminuindo esse estresse, pois quando absorvido pelas plantas promove aumento de compostos antioxidantes, tais como: carotenoides, flavonoides e de enzimas antioxidantes, que reduz o dano oxidativo. Além disso, esse elemento exerce um importante papel no fortalecimento da parede celular e na melhoria do processo fotossintético, conferindo maior proteção à planta contra altas temperaturas e luminosidade (KHAN et al, 2023).…”

“…Nos últimos anos, a aplicação de selênio tem sido reconhecida como uma estratégia interessante nas plantas devido não só a capacidade de estimular o crescimento, mas de minimizar os efeitos adversos dos estresses abióticos, como no caso do metal, através da modulação de diferentes mecanismos (TITOV et al, 2022). Tem sido relatado que dependendo da concentração de Se aplicada sob plantas estressadas por metais, os efeitos de proteção conferidos pelo Se estão envolvidos na ativação de vias distintas de sinalização, regulação positiva do metabolismo antioxidante, refletindo por sua vez, no crescimento e também na translocação e distribuição do metal (KHAN et al, 2023).…”

“…Nesse sentido, o Se desempenha papéis significativos no metabolismo vegetal, pois atua como agente antioxidante eliminando o acúmulo de espécies reativas de oxigênio (ERO), melhora a homeostase iônica que auxilia no alívio do estresse oxidativo e no aparato fotossintético, proporcionando flexibilidade contra o estresse dos metais (KHAN et al, 2023).…”
