As the applications of non-thermal terahertz (THz) radiation expand, especially in biomedicine, evidence is accumulating that this type of radiation can influence both biological molecules directly and cellular processes in general. Moreover, there is evidence of changes in intracellular processes under the influence of THz radiation at the transcription level. Thus, in the E. coli cell, THz irradiation changes the expression of genes involved in protection from oxidative stress, maintaining the homeostasis of transition metals, amino acid metabolism, etc. (Demidova et al., 2013; 2016; Serdyukov et al., 2020; 2021). However, identifying the biological effects of THz radiation in thermosensitive organisms is associated with a number of technical difficulties, one of which is maintaining optimal temperature (Sun et al., 2021). This study analyzed the effect of THz radiation on gene expression in the cells of the thermophilic bacterium Geobacillus icigianus, which is adapted to a wide temperature range from 50 to 75°C (Bryanskaya et al., 2015). It was previously noted that THz irradiation did not lead to the appearance of heat shock proteins in its cell (Bannikova et al., 2022).
