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...
Chronic ionising radiation exposure is a main consequence of radioactive pollution the environment. The development functional genomics approaches coupled with morphological and physiological studies allows new insights into plant adaptation to life under chronic irradiation. Using morphological, reproductive, physiological, transcriptomic experiments, we evaluated way in which Arabidopsis thaliana natural accessions from Chernobyl exclusion zone recover low-dose acute high-dose...
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...
Our understanding of the long-term consequences chronic ionising radiation for living organisms remains scarce. Modern molecular biology techniques are helpful tools researching pollutant effects on biota. To reveal phenotype plants growing under exposure, we sampled Vicia cracca L. in Chernobyl exclusion zone and areas with normal backgrounds. We performed a detailed analysis soil gene expression patterns conducted coordinated multi-omics analyses plant samples, including transcriptomics,...
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...
Plant growth response to γ-irradiation includes stimulating or inhibitory effects depending on plant species, dose applied, stage of ontogeny and other factors. Previous studies showed that responses irradiation could depend ABA accumulation signaling. To elucidate the role in photosynthetic irradiation, lines Col-8, abi3-8 aba3 -1 Arabidopsis thaliana were used. Seeds γ-irradiated using 60 Co range 50-150 Gy. It was revealed 150 Gy affected germination parameters Col-8 lines, while line...
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. Small doses of radiation stimulate the growth and development plants including seed germination. ABA plays a key role not only in dormancy germination but also regulation adaptive reactions plants.
 The aim our work was to study effect -irradiation barley seeds small on expression genes encoding biosynthesis enzyme 9-cis-epoxycarotenoid dioxygenase (HvNCED1) catabolism 8-hydroxylase (HvABA8OH-1).
 Materials Methods. were irradiated at dose range 450 Gy rate 60 Gy/h,...
