“…The pollution of agricultural soils and waters by As contamination has led to serious environmental problems in the productivity of crop plants. As toxicity affects photosynthesis by reducing the chlorophyll content, which negatively influences general plant growth and important metabolic processes, and by inhibiting adenosine triphosphate (ATP) biosynthesis by disrupting phosphorus uptake in the roots (Panda et al, 2010; Finnegan and Chen, 2012; Gupta and Ahmad, 2014; Jung et al, 2017b). Recently, some studies have demonstrated that the exogenous application of hydrogen sulfide (Singh et al, 2015b; Li et al, 2016; Chen et al, 2017), sulfur (Khan et al, 2015; Jung et al, 2017a; Tian et al, 2017), AsA (Jung et al, 2018; Semida et al, 2018), or GSH (Shri et al, 2009; Chen et al, 2010; Mostofa et al, 2014; Kim et al, 2017) may alleviate different heavy metal stresses.…”
