It has previously been shown that across different arsenic (As) soil environments, a decrease in grain selenium (Se), zinc (Zn), and nickel (Ni) concentrations is associated with an increase in grain As. In this study we aim to determine if there is a genetic element for this observation or if it is driven by the soil As environment. To determine the genetic and environmental effect on grain element composition, multielement analysis using ICP-MS was performed on rice grain from a range of rice cultivars grown in 4 different field sites (2 in Bangladesh and 2 in West Bengal). At all four sites a negative correlation was observed between grain As and grain Ni, while at three of the four sites a negative correlation was observed between grain As and grain Se and grain copper (Cu). For manganese, Ni, Cu, and Se there was also a significant genetic interaction with grain arsenic indicating some cultivars are more strongly affected by arsenic than others.
先前的研究表明，在不同的砷（As）土壤环境中，谷物中硒（Se）、锌（Zn）和镍（Ni）浓度的降低与谷物中 As 的增加有关。在这项研究中，我们旨在确定这种观察结果是否存在遗传因素，或者是否是由土壤 As 环境驱动的。为了确定遗传和环境对谷物元素组成的影响，使用 ICP-MS 对来自孟加拉国和西孟加拉邦的 4 个不同田间地点种植的一系列水稻品种的水稻籽粒进行了多元素分析。在所有四个地点，都观察到谷物 As 与谷物 Ni 之间呈负相关，而在四个地点中的三个地点，都观察到谷物 As 与谷物 Se 和谷物铜（Cu）之间呈负相关。对于锰、Ni、Cu 和 Se，它们与谷物砷也存在显著的遗传相互作用，表明一些品种比其他品种受砷的影响更大。
