Abstract: Arsenic (As) is a highly toxic pollutant in the environment. Although both inorganic and organic types of arsenic occur in the environment, the most common inorganic forms of As that adversely affect plants that are arsenite (As III) and arsenate (As V).Arsenic (As) is a common soil contaminant that can be accumulated in plant parts. The ability to detect As in contaminated plants is an important tool to minimize As-induced health risks in humans. Near-infrared (NIR) spectra are strongly affected by leaf structural characteristics. Therefore, quantitative analyses of structural changes in the arrangement of mesophyll cells caused by As will help to explain spectral responses to As. Despite no evidence for Arsenic being essential for plant growth, exposure of roots to this element can cause its acceptance primarily via transporters responsible for the transport of essential mineral nutrients. Arsenic exposure even at low concentrations disturbs the plant’s normal functioning via extreme generation of reactive oxygen species, a condition known as oxidative stress leading to an imbalance in the redox system of the plants. This is associated with considerable damage to the cell components thus impairing normal cellular functions and activation of several cell survival andcell death pathways. To counteract this oxidative disorder, plants possess natural defense mechanisms such as chemical species and enzymatic antioxidants. Various approaches to improve As-induced oxidative tolerance in plants such as exogenous supplementation of effective growth regulators, protectant chemicals, transgenic approaches, and genome editing are also discussed thoroughly in this review.Modification of several metabolic pathways, such as glutathione production, has been shown to lead to increased arsenic tolerance in plants. Species- and cultivar-dependent variation in arsenic sensitivity and the remodelling of metabolite pools that occurs in a response to Arsenic exposure gives hope that additional metabolic pathways associated with Arsenic tolerance will be identified.
