“…The beneficial effects of low-dose environmental contaminants is widely recognized in the field of toxicology and medicine, where it is defined as “hormesis”, characterized by a biphasic adaptive response [ 38 , 39 , 40 ]. It is also found that hormesis can improve the adaptation of plants to some adverse environments, such as the low doses of nitrogen, lanthanum, ozone, ultraviolet radiation and herbicides [ 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 ]. Some researchers observed that hormesis can protect plants against environmental stress and enhance plant biomass productivity and functional components [ 49 , 50 , 51 ].…”

“Hormesis” is considered a dose–response phenomenon mainly observed at hyperaccumulator plants under heavy metals stress. In this study, the effects of electric fields on hormesis responses in Lonicera japonica Thunb. under cadmium (Cd) treatments were investigated by assessing the plant growth and photosynthetic characteristics. Under Cd treatments without electric fields, the parameters of plant growth and photosynthetic characteristics increased significantly when exposed to 5 mg L−1 Cd, and decreased slightly when exposed to 25 mg L−1 Cd, showing an inverted U-shaped trend, which confirmed that low concentration Cd has a hormesis effect on L. japonica. Under electric fields, different voltages significantly promoted the inverted U-shaped trend of the hormesis effect on the plant, especially by 2 V cm−1 voltage. Under 2 V cm−1 voltage, the dry weight of the root and leaf biomass exposed to 5 mg L−1 Cd increased significantly by 38.38% and 42.14%, and the photosynthetic pigment contents and photosynthetic parameters were also increased significantly relative to the control, indicating that a suitable electric field provides better improvements for the hormesis responses of the plant under Cd treatments. The synergistic benefits of the 5 mg L−1 Cd and 2 V cm−1 electric field in terms of the enhanced hormesis responses of growth and photosynthetic characteristics could contribute to the promoted application of electro-phytotechnology.

“…Common barley, Hordeum vulgare L., is one of the most important crops with a high nutritional value and adaptability, although its maximum productivity in the world has declined due to climate change [14][15][16][17]. Barley cultivars readily respond to low-dose seed radiation treatment [18], and we revealed several candidate metabolites and genes as possible players in the radiation hormesis effect in this crop [11,[19][20][21]. Changes in the expression of rice homologues PM19L, CML31, and AOS2 in seedlings of barley cultivars with different sensitivities to irradiation were earlier proposed as possible determinants of radiation hormesis [21].…”

The stimulation of growth and development of crops using ionising radiation (radiation hormesis) has been reported by many research groups. However, specific genes contributing to the radiation stimulation of plant growth are largely unknown. In this work, we studied the impact of the low-dose γ-irradiation of barley seeds on the growth dynamics and gene expression of eight barley cultivars in a greenhouse experiment. Our findings confirmed that candidate genes of the radiation growth stimulation, previously established in barley seedlings (PM19L-like, CML31-like, and AOS2-like), are significant in radiation hormesis throughout ontogeny. In γ-stimulated cultivars, the expression of these genes was aligned with the growth dynamics, yield parameters, and physiological conditions of plants. We identified contrasting cultivars for future gene editing and found that the γ-stimulated cultivar possessed some specific abiotic stress-responsive elements in the promotors of candidate genes, possibly revealing a new level of radiation hormesis effect execution. These results can be used in creating new productive barley cultivars, ecological toxicology of radionuclides, and eustress biology studies.

“…Being an adaptive response, the activation of plant metabolism also exhibits a hormetic behavior [ 87 , 88 , 89 ], and deliberately exposing crops to low-dose stress is a convenient means for stimulating metabolites accumulation [ 90 ]. Moreover, the metabolomics analysis of plant stress response along with bioinformatics makes it possible to find candidate markers for directing crop breeding and predicting crop performance under environmental stress [ 91 ].…”

Plant stress is one of the most significant factors affecting plant fitness and, consequently, food production. However, plant stress may also be profitable since it behaves hormetically; at low doses, it stimulates positive traits in crops, such as the synthesis of specialized metabolites and additional stress tolerance. The controlled exposure of crops to low doses of stressors is therefore called hormesis management, and it is a promising method to increase crop productivity and quality. Nevertheless, hormesis management has severe limitations derived from the complexity of plant physiological responses to stress. Many technological advances assist plant stress science in overcoming such limitations, which results in extensive datasets originating from the multiple layers of the plant defensive response. For that reason, artificial intelligence tools, particularly Machine Learning (ML) and Deep Learning (DL), have become crucial for processing and interpreting data to accurately model plant stress responses such as genomic variation, gene and protein expression, and metabolite biosynthesis. In this review, we discuss the most recent ML and DL applications in plant stress science, focusing on their potential for improving the development of hormesis management protocols.
