Abstract At low intensity, certain stress conditions may have a positive effect on growth and development of plants (eustress). Growth stimulation barley after gamma irradiation seeds in doses was observed as an increase root shoot lengths. Hydrogen peroxide concentrations shoots irradiated were significantly higher than control, while the opposite roots. To elucidate molecular basis seeds, we performed transcriptomic analysis embryos at different stages seed germination. The data correlated...
The stimulation of growth and development crops using ionising radiation (radiation hormesis) has been reported by many research groups. However, specific genes contributing to the plant are largely unknown. In this work, we studied impact low-dose γ-irradiation barley seeds on dynamics gene expression eight cultivars in a greenhouse experiment. Our findings confirmed that candidate stimulation, previously established seedlings (PM19L-like, CML31-like, AOS2-like), significant hormesis...
The favorable responses of crop species to low-dose γ irradiation can help develop cultivars with increased productivity and improved stress tolerance. In the present study, we tried reveal candidate metabolites involved in growth stimulation barley seedlings after applying γ-radiation (60Co) seeds. Stimulating doses (5-20 Gy) provided a significant increase shoot length biomass, while relatively high dose 100 Gy led inhibition growth. Gas chromatography-mass spectrometry metabolomic...
Gamma (γ)-irradiation of plants at low doses can provoke a broad range growth-stimulating effects. In order to reveal universal target genes that are involved in molecular pathways radiation hormesis establishment, we studied nine barley cultivars for their tolerance γ-irradiation seeds. Four morphological traits were assessed seedlings after seeds 20 Gy. Nine sorted according the sensitivity irradiation as γ-stimulated, “no effect”, or γ-inhibited. Gene expression 17 candidate was evaluated...
The development of adaptation strategies for crops under ever-changing climate conditions is a critically important food security issue. Studies barley responses to ionising radiation showed that this evolutionarily ancient stress factor can be successfully used identify molecular pathways involved in range abiotic stressors. In order potential contributors resilience, we examined the transcriptomic profiles seedlings after exposure γ-rays, electrons, and protons. A total 553 unique...
Barley is the main forage crop in Russian Federation. grain also used for food and brewery (Filippov, 2013). It common knowledge that low doses of gamma irradiation can have a stimulating effect on growth development plants, particular barley. However, there lack about molecular pathways responsible formation stimulation after low-dose seed irradiation. The use varieties with different radio sensitivity to will allow studying specific mechanisms form effect. Such could further help large...
Background. The study of the long-term effects chronic radiation exposure on plants and animals, which are still subject scientific discussion, is necessary to understand consequences accidents. After Fukushima nuclear power plant accident, some young pines spruces showed an increased frequency apical dominance cancelling. most probable cause observed morphoses associated with damage meristem coniferous by in first year when they received highest absorbed doses. If this hypothesis true, then...
A comprehensive study of the biological effects chronic radiation exposure on populations white clover (Trifolium repens L.) from Chernobyl exclusion zone was carried out. The leaf area, all marks and fluctuating asymmetry were estimated; spectrophotometric assessment accomplished activity antioxidant enzymes (catalase, glutathione guaiacol peroxidases, ascorbate peroxidase, superoxide dismutase); concentration main phytohormones (abscisic indoleacetic acids) measured; analysis...
