Effect of Arsenic in germination, growth and biochemistry of Rice (Oryza sativa)

Abstract

Abstract-Arsenic is a highly toxic metalloid element and occurs in many minerals

Silicon nanoparticles decrease arsenic translocation and mitigate phytotoxicity in tomato plants

“…7d). Biswas et al (2016) reported that exposure to As in two rice cultivars, at 4 mg L − 1 , decreased total protein content down to 48.56% and 68.34%. Apparently, when trace metal concentrations are high, higher generation of ROS and therefore greater oxidative stress is observed (Gupta et al 2009) which can cause the reduction in proteins as a result of a greater oxidative damage due to part of the trace elements (Sanal et al 2014).…”

Laboratory Germination Experiment for Assessing the Phytotoxic Effect of Arsenic on the Growth Attribute of Different Crops

“…7). Biswas et al, [14] reported that the vigour index exhibits a direct decrease when the concentration of sodium arsenate is increased since it depends on root length, shoot length, and germination percentage [14]. This result was in line with study conducted by Baruah et al, [13], the results of the experiment revealed that the seedlings treated with different concentration of different heavy metals showed the highest reduction (83.4%) in vigour index in 175 mg L -1 of copper (Cu) in wheat followed by 220 mg L -1 of lead (Pb) in pea (79.2%) and 220 mg L -1 (Cd) of cadmium in wheat (78.8%) [13].…”

“…The root length might have a relatively strong suppressive effect than that of the shoot length. Biswas et al, [14] reported that trivalent (As III) and pentavalent (As V) arsenic are accumulated by plants. These forms interfere with phosphate in various metabolic pathways, and interact with sulfhydryl groups on proteins.…”

“…These forms interfere with phosphate in various metabolic pathways, and interact with sulfhydryl groups on proteins. Due to their initial contact with arsenic compounds, roots have been shown to be more influenced than shoots [14]. Similarly, Bianucci et al, [15] investigated the influence of As on peanut plants reduction in plant growth, as well as a loss in root volume, architecture, and lateral root development [15].…”

“…Maize Black gram Rice Groundnut Tomato biosynthetic route in decrease in chlorophyll synthesis caused by the production of ROS Upadhyaya et al, [18]. According to [14] higher arsenic concentrations can cause the damage to the shape of the chloroplast which changes in the accumulation of chlorophyll contents in rice leaves can also result from higher arsenic concentrations. Baruah et al, [13] reported that the reduced carbohydrate content of the emerging seedlings under metal exposure might be due to inhibition of chlorophyll biosynthesis as observed from the lower chlorophyll content [13].…”
