Article Synopsis
- The study focuses on how plants respond to extreme conditions like microgravity and radiation, which is important for space exploration and improving plant resilience in outer space.
- Researchers created a 3D clinostat to replicate microgravity conditions and used proton irradiation to simulate space conditions, studying the effects on plant seeds from the Chernobyl exclusion zone.
- Results showed that one plant type was resilient to these conditions, while others experienced inhibited photosynthesis; findings and tools developed are available for further research in space biology.
Article Synopsis
- - The study focuses on developing crop adaptation strategies in response to climate change, specifically through investigating barley's reaction to ionizing radiation as a means to understand stress resilience.
- - Researchers identified 553 genes that were upregulated and 124 downregulated in barley seedlings after exposure to different types of radiation, with the highest activity seen in samples exposed to electrons.
- - Key genes relating to stress responses, such as those involved in DNA repair, ROS response, and photosynthesis, were significantly activated, suggesting that understanding these pathways could enhance plant stress tolerance in agriculture.
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.

Modern molecular biology techniques are helpful tools for researching pollutant effects on biota. To reveal the molecular phenotype of plants growing under chronic radiation exposure, we sampled L.

The development of functional genomics approaches coupled with morphological and physiological studies allows new insights into plant adaptation to life under chronic irradiation. Using morphological, reproductive, physiological, and transcriptomic experiments, we evaluated the way in which natural accessions from the Chernobyl exclusion zone recover from chronic low-dose and acute high-dose γ-irradiation of seeds.

Previous studies showed that responses to irradiation could depend on ABA accumulation and signaling. To elucidate the role of ABA in growth and photosynthetic responses to irradiation, lines Col-8, and of were used.
