“…Arsenic is well known to adversely affect the plant growth and development after its entry to plant system ( Gupta et al, 2009 ; Dixit et al, 2015c ; Pandey and Gupta, 2015 ). In the hydroponic medium under anaerobic condition most of As V gets converted to As III .…”

Nitric oxide (NO) is a gaseous signaling molecule and has a profound impact on plant growth and development. It is reported to serve as pro oxidant as well as antioxidant in plant system. In the present study, we evaluated the protective role of NO against arsenate (AsV) toxicity in rice plants. AsV exposure has hampered the plant growth, reduced the chlorophyll content, and enhanced the oxidative stress, while the exogenous NO supplementation has reverted these symptoms. NO supplementation has reduced the arsenic (As) accumulation in root as well as shoot. NO supplementation to AsV exposed plants has reduced the gene expression level of OsLsi1 and OsLsi2. AsV stress significantly impacted thiol metabolism, it reduced GSH content and GSH/GSSG ratio, and enhanced the level of PCs. NO supplementation maintained the GSH/GSSG ratio and reduced the level of PCs. NO supplementation reverted AsV induced iron deficiency in shoot and had significant impact of gene expression level of various iron transporters (OsYSL2, OsFRDL1, OsIRT1, and OsIRO2). Conclusively, exogenous application of NO could be advantageous against AsV toxicity and could confer the tolerance to AsV stress in rice.

“…3 Sulfur addition decreased the As uptake and content in the shoot, modulated thiol metabolism, glycolysis and amino acid in Oryza sativa. 4 Apart from the direct effect, the interaction of S with other molecules is very common to counteract abiotic stress. Sulfur can interact with different phytohormones including auxins (AUX), gibberellins (GA), cytokinins (CK), abscisic acid (ABA), ethylene (ET), jasmonic acid (JA) and salicylic acid (SA) under abiotic stress situation, and positively regulates plant defense 5 ( Figure 1).…”

Sulfur (S) is a macronutrient for the plant, which has an immense role in basic plant processes and regulation of several metabolic pathways. It has also a major role in providing protection against adverse conditions. Sulfur-containing amino acids and metabolites maintain plant cell mechanisms to improve stress tolerance. It interacts with several biomolecules such as phytohormones, polyamines, nitric oxide (NO), and even with other plant nutrients, which can produce some derivatives those are essential for abiotic stress tolerance. Different S derivatives stimulate signaling cascades, for the upregulation of different cellular messengers such as abscisic acid, Ca, and NO. Sulfur is also known to interact with some essential plant nutrients by influencing their uptake and transport, hence, confers nutrient homeostasis efficiencies. This review focuses on how S is interacted with several signaling molecules like NO, glutathiones, phytohormones, hydrogen sulfide, polyamines, etc. This is a concise summary aimed at guiding the researchers to study S-related plant processes in the light of abiotic stress tolerance.

“…It deposits the SiO 2 in the apoplast of the leaf surface and roots, which forms a barrier to the flow of metallic ions into grains [28,29]. Arsenic (As) uptake reduce in rice crops through the application of sulfur (S) which is involved in di-sulfide linkage in many proteins and plays a crucial role in As detoxification [30].…”

19Arsenic (As) is a carcinogenic substance. It increased in crop grown in field soil from ground water 20 irrigation. Subsequently As transport into the human body through food chains. The reduction of 21 As transport in root, shoot and grain of pea genotypes is significantly important to protect human 22 health. This research is focused on the biomass growth and alleviation of As accumulation in root, 23 shoot and grain of pea genotypes in high As soil (30mgkg -1 ) amended with arbuscular mycorrhizal 24 fungi (AMF), biochar (BC) of rice husk and saw dust, selenium (Se), silica-gel (Si), and sulfur 25 (S). Shoot length, root, shoot and pod mass were generally higher in pea crops grown in soil 26 amended with AMF, Se, Si-gel and S. Rice husk and saw dust BC less consistently increased 27 some growth parameters, particularly in genotype BARI Motor 2. However, the BC's more often 28 reduced growth and pod mass. All treatments significantly reduced As concentration in tissues; As 29 in grains was reduced on average 60% by any of the soil amendments. AMF, Se and Si-gel all 30 were found more effective than BC for the reduction of As uptake in pea crops. As in grains was 31 reduced 77% by AMF, 71% by Se and 69% by Si-gel on average. As in root, shoot, and grain was AMF, Se, S, Si-gel and BC reduce arsenic uptake in plant biomass 32 also affected by variety; in control treatments, total As uptake in plants pot -1 of BARI Motor 1 and 33 3 was found 60 to 70% higher than BARI Motor 2. Comparing the variety and treatment with most 34 As in grains (BARI Motor 1 control, 0.35 mg As kg -1 ) and least As in grains (BARI motor 1, 2 & 35 3 with AMF with 0.07 mg As kg -1 ), the choice of variety and soil amendment could reduce human 36 intake of As through pea by 80%. It is recommended that choice of pea variety and soil amendment 37 with AMF and Se have great potential for improving the nutritional quality of pea grown in As 38 contaminated soil, as well as reducing As transfer to human bodies through food chains in pea 39 crops.40 41 45 major concern of ingested As is cancer, primarily of skin, bladder, and lung [1]. This metal moves 46 into the human body through the assimilation of food or water. Ground water is the main source 47 for the contamination of As in the soil. It is a global problem, including Bangladesh, Chile, China, 48 Vietnam, Taiwan, India, and the United States [2]. Consequently, As is the number one hazardous 49 substance according to the priority list of the Agency for Toxic Substances and Disease Registry 50 [3].51 Simultaneously, Field pea (Pisum sativum) is one of the delicious and nutritious pulse crop in 52 Bangladesh as well as throughout the world. It supplies high concentration of antioxidants, starch, 53 protein, fiber, vitamins, minerals and phytochemicals [4]. Fiber in seed coat and cotyledon of pea 54 improves gastrointestinal function. Pea protein, when hydrolyzed, may yield peptides with AMF, Se, S, Si-gel and BC reduce arsenic uptake in plant biomass 55 different bio-active compounds [5...
