“…The effect of x-ray irradiation on NRA has not been reported yet. Though the increased expression of Ribulose bis phosphate carboxylase and decreased expression of poly (ADP-ribose) polymerase in response to irradiation of dwarf bean plants by x-radiations has been reported [6]. In the present investigation, the nitrate reductase activity of the developing leaves was reduced significantly with perfect correlation in response to irradiation (Table 3).…”

“…Although reduced leaf growth parameters, such as leaf area, dry mass, pigment content etc. upon irradiation of dwarf bean plants to x-radiations, have been reported [6], the synchroton x-ray irradiation affecting growth has not been reported yet. In this study, the effect of x-ray exposure of Phaseolus vulgaris seeds on phosphate mobilization in soaked seeds, overall growth and nitrate assimilation in seedlings has been studied.…”

Irradiated seeds of Phaseolus vulgaris cv. Rajmah using Synchroton X-Ray Beam (BL-07) at RRCAT, Indore at various doses in the range of 0.5 -10 Gy were used to raise the seedling and the growth status at different stages was evaluated. Prior to germination, in the seeds soaked for 24 hours, the water regain remained unaffected by seed irradiation at 1 -10 Gy doses, while the acid phosphatase activity was significantly reduced. Strong correlation (R 2 = 0.685) between irradiation dose and enzyme activity also resulted. Analysing seed irradiation effect on seed development up to 4 days, % germination, germination index (GI), seedling wt, and seedling vigour were non significantly decreased at 5.0 Gy dose. The overall growth of 10 days old seedlings raised from irradiated seeds was substantially reduced at irradiation doses of 2 and 5 Gy exerting strong −ve correlation. Also % germination and seed vigour index (SVI) were prominently decreased due to seed irradiation. The nitrogen status of the seedlings, reflected by nitrate reductase activity (NRA) was significantly reduced in response to irradiation exerting strong correlation. The results demonstrate decreased phosphate mobilization in soaked seeds, time dependent decreased growth being more substantial with longer duration and reduced nitrate assimilation due to seed irradiation with Synchroton X-Ray Beam.

“…anthocyanin rich extract) enzymes such as POD, SOD, GR, and APX. The increase or decrease in the activity of the enzymes cited above depends on the sensitivity of the plant species and the level of IR involved (Wada et al 1998;Zaka et al 2002;Gill and Tuteja 2010;Arena et al 2014). The results of the present study show that POD activity was inhibited while SOD, APX, and GR activities were enhanced by treatment with IR in both barley cvs (Fig.…”

The effect of anthocyanin-rich bilberry extract on the antioxidant system in roots of barley (Hordeum vulgare L.) cultivars under ionizing radiation

The effects of extracted and purified anthocyanin (ACY) from mature berries of Vaccinium myrtillus L., on growth parameters, antioxidant enzymes, total phenolic (TP) content, total flavonoid (TF) content, and 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity were investigated in the roots of barley (Hordeum vulgare L.) cultivars Akhisar-98 and Erginel-90 under ionizing irradiation (IR; 10 Gy). The responses to IR and ACY-rich extract treatment in the two cultivars differed; Akhisar-98 was more radiosensitive than Erginel-90 in terms of root development, but IR-induced decreases in Akhisar-98 root length were alleviated by ACY-rich extract (100 lM). Peroxidase (POD) activity in Akhisar and Erginel cultivars decreased, while superoxide dismutase (SOD), glutathione reductase (GR), and ascorbate peroxidase (APX) activities increased. The ACY-rich extract increased POD activity, and decreased SOD, GR, and APX activities in the two barley cultivars. Although TP content increased in the Erginel cultivar more than the Akhisar cultivar, TF contents did not differ between the control and irradiated roots of the Erginel cultivar. Since TP content, TF content, and DPPH radical scavenging activity increased and H 2 O 2 content decreased after ACYrich extract treatment, ACY-rich extract treatment enhanced antioxidant activity, especially in the Akhisar cultivar. Treatment with ACY-rich extract conferred a greater tolerance to IR stress, especially after irradiation, in the two barley cultivars exposed to IR and exogenic ACYrich extract. These findings indicate that the Erginel cultivar is more IR-tolerant than the Akhisar cultivar and that exogenous ACY-rich extract treatment promotes antioxidant capacity in barley cultivars under IR stress.

“…In Space, a large fraction of the dose is delivered by protons (approximately 87%), which are low-LET particles with similar effectiveness compared to X-rays. Therefore, initial studies can exploit conventional X-rays as the reference radiation to obtain data which are the necessary basis for future comparison using accelerated ion beams [13, 14]. The severity of the effects of low- and high-LET ionising radiation depends on several factors related to the radiation itself (e.g., type, total dose, and dose rate) and to plant features (e.g., species, cultivar, plant age, complexity of the target organ or tissue, and level of ploidy) [2, 15].…”

Plants can be exposed to ionising radiation not only in Space but also on Earth, due to specific technological applications or after nuclear disasters. The response of plants to ionising radiation depends on radiation quality/quantity and/or plant characteristics. In this paper, we analyse some growth traits, leaf anatomy, and ecophysiological features of plants of Solanum lycopersicum L. “Microtom” grown from seeds irradiated with increasing doses of X-rays (0.3, 10, 20, 50, and 100 Gy). Both juvenile and compound leaves from plants developed from irradiated and control seeds were analysed through light and epifluorescence microscopy. Digital image analysis allowed quantifying anatomical parameters to detect the occurrence of signs of structural damage. Fluorescence parameters and total photosynthetic pigment content were analysed to evaluate the functioning of the photosynthetic machinery. Radiation did not affect percentage and rate of seed germination. Plants from irradiated seeds accomplished the crop cycle and showed a more compact habitus. Dose-depended tendencies of variations occurred in phenolic content, while other leaf anatomical parameters did not show distinct trends after irradiation. The sporadic perturbations of leaf structure, observed during the vegetative phase, after high levels of radiation were not so severe as to induce any significant alterations in photosynthetic efficiency.
