摘要

砷(As3+)是一种在地壳中发现的有毒类金属,其浓度升高是人类健康的一个问题,因为水稻是印度东部的主要粮食,而水涝稻田环境为更多的As3+吸收提供了机会。镁(Mg2+)是一种重要的植物营养物质。目前的工作是探索通过施用Mg2+来降低As3+对植物的毒性。结果令人印象深刻,与对照相比,根冠生物量比增加了1.5倍以上。总蛋白质含量提高2倍。碳水化合物和叶绿素含量比对照增加了2 ~ 3倍。另一方面,随着Mg2+剂量的增加,丙二醛含量呈下降趋势。芯片研究表明,在Mg2+存在的情况下,As3+与As3+的相互作用更好,但有趣的是没有应激症状。上述研究结果表明,Mg2+能有效降低As3+对植物的胁迫作用。

COPING THE ARSENIC TOXICITY IN RICE PLANT WITH MAGNESIUM ADDENDUM FOR ALLUVIAL SOIL OF INDO-GANGETIC BENGAL, INDIA
Arsenic (As3+) is a toxic metalloid found in the earth’s crust, its elevated concentration is a concern for human health because rice is the staple grain in eastern part of India and the waterlogged rice field environment provides opportunity for more As3+ uptake. Magnesium (Mg2+) is an important plant nutrient. Present work is a search for reducing As3+ toxicity in plants through Mg2+ application. The findings are quite impressive, the root to shoot biomass ratio showed more than 1.5 times increase compared to the control. Total protein content increased 2 folds. Carbohydrate and chlorophyll content increased two to three times compared to control. On the other hand, Malondialdehyde content showed a decline with the application of increased Mg2+ dose. The in-silico study shows a better interaction with As3+ in presence of Mg2+ but interestingly without stress symptoms. These findings from the research indicate that Mg2+ application can be effective in reducing As3+ induced stress in plants.
