Electromagnetic energy is the “backbone” of wireless communication systems, and its progressive use is considered to have a low but measurable impact on a wide range of biological systems. Even though a growing amount of data has reported electromagnetic energy absorption in humans along with subsequent biological effects, the consequences of electromagnetic energy absorption on plants have been insufficiently addressed. The higher surface to volume ratio along with the enormous water‐ion concentrations makes the plant an ideal model to interact with non‐ionizing electromagnetic radiation. In this study, controlled and periodic electromagnetic exposure of 1837.50 MHz, 2.75 W/m² for 6 h a day on a popular rice variety (var. Satabdi) reduced the seed germination rate. The same dose of periodic electromagnetic exposure upregulated phytochrome B and phytochrome C gene transcripts in 12‐day‐old seedlings, whereas, in 32‐day‐old plants, the dose upregulated calmodulin and phytochrome C while the bZIP1 gene showed repression. However, the transcript abundance of bZIP1, phytochrome B, and phytochrome C genes was enhanced even in 12‐day‐old Satabdi seedlings following instantaneous short‐duration (2 h 30 min) controlled electromagnetic exposure to 1837.50 MHz, 2.75 W/m². The reported responses in rice were observed below the international electromagnetic regulatory limits. Thus, rice plants perceived electromagnetic energy emitted by the wireless communication system as abiotic stress as per its response by upregulation or repression of known stress‐sensing genes.

电磁辐射引起水稻的生理和分子变化


电磁能是无线通信系统的“支柱”，其逐步使用被认为对广泛的生物系统产生虽小但可测量的影响。尽管越来越多的数据报道了人体电磁能吸收以及随后的生物效应，但电磁能吸收对植物的后果尚未得到充分解决。较高的表面积与体积比以及巨大的水离子浓度使植物成为与非电离电磁辐射相互作用的理想模型。在这项研究中，对流行的水稻品种（变种Satabdi ）进行 6 公顷天的 1837.50 MHz、2.75 W/m ²的受控周期性电磁暴露降低了种子发芽率。相同剂量的周期性电磁暴露上调了 12 日龄幼苗中的光敏色素 B 和光敏色素 C 基因转录本，而在 32 日龄的植物中，该剂量上调了钙调素和光敏色素 C，而 bZIP1 基因则表现出抑制。然而，即使在 12 天大的Satabdi幼苗中，在瞬时短时间（2 小时 30 分钟）受控电磁暴露于 1837.50 MHz、2.75 W/m ²后，bZIP1、光敏色素 B 和光敏色素 C 基因的转录本丰度也会增强。观察到的水稻反应低于国际电磁监管限值。因此，水稻植物将无线通信系统发出的电磁能视为非生物胁迫，根据其通过上调或抑制已知胁迫感应基因的反应。生物电磁学。 © 2020 生物电磁学会
