“…In the previous studies, it has been indicated that the gamma-ray irradiation can improve and promote the abiotic stress tolerance in plants in addition to be used to screen disease-resistant crop varieties and sterilization [ 63 ]. Furthermore, it has been pointed out that the gamma-ray irradiation can regulate the biosynthesis of many secondary key metabolites and osmolytes, and regulate various metabolic activities to generate tolerance to against the environmental stresses [ 64 ].…”

Gamma-ray irradiation is an effective and clean method of sterilization by inactivating microorganisms. It can also be applied to induce anti-oxidants for future application. In this study, the mung bean (Vigna radiata) was exposed to gamma-ray irradiation under the dose of 0, 5 or 10 kGy. With increasing irradiation doses, the concentrations of malondiadehyde decreased while the levels of total flavonoids and DPPH (1,1-diphenyl-2-picrylhydrazyl) radical scavenging activity increased. It has been shown that consuming flavonoids can provide protective effects. In addition, proteomic analysis identified several proteins having anti-oxidant activities in the 5 kGy irradiated group. These proteins are Apocytochrome f, Systemin receptor SR 160, DELLA protein DWARF8, DEAD-box ATP-dependent RNA helicase 9, ζ-carotene desaturase (ZDS), and Floral homeotic protein AGAMOUS. Our findings indicate that plants contain a variety of phytochemicals and antioxidant proteins which may effectively prevent oxidative stress caused by irradiated peroxidation.

“…Among them, gamma radiation (an example of ionizing radiation) has been successfully used in crop improvement and the generation of new cultivars. Due to its shorter wavelength and higher energy, gamma radiation is capable of penetrating deeper into plant tissues 12 , thus inducing a wide range of mutations which may be desirable to farmers or crop breeders, such as disease and pest resistance, semi-dwarfism, early maturity, and improved plant stature 12 , 13 . Subsequently, the mutants with these desirable traits would be subjected to multi-location field trials (with a minimum of two subsequent generations) to determine their stability, prior to market release 14 – 16 .…”

Due to their sessile nature, plants are exposed to various environmental stressors such as exposure to high levels of harmful ultraviolet (UV), ionizing, and non-ionizing radiations. This exposure may result in various damages, ranging from DNA and chromosomal aberrations to phenotypic abnormalities. As an adaptation, plants have evolved efficient DNA repair mechanisms to detect and repair any damage caused by exposure to these harmful stressors to ensure their survival. In this study, the effects of gamma radiation (as a source of ionizing radiation) on clonal Ananas comosus var. MD2 was evaluated. The morphology and physiology of the clonal plantlets before and after exposure to gamma radiation were monitored at specific time intervals. The degree of genetic variation between the samples pre- and post-irradiation was also analyzed by using inter-simple sequence repeat (ISSR) markers. The resulting data revealed that the heights of the irradiated plantlets were significantly reduced (compared to control), but improved with the recovery period. Irradiated samples also exhibited relatively good photosynthetic efficiency that further improved as the plantlets recover. These observations were supported by the ISSR analysis, where the genetic dissimilarities between the irradiated samples and control were reduced by 0.1017, after 4 weeks of recovery. Overall, our findings suggested that the phenotype recovery of the clonal A. comosus var. MD2 plantlets was contributed by their ability to detect and repair the DNA lesions (as exemplified by the reduction in genetic dissimilarity after 4 weeks) and hence allow the plantlets to undergo phenotype reversion to normal plant stature.

“…This result is supported by Harun-Or-Rashid et al (2019) who found that all the 4 doses of irradiation showed a significant effect on incidence and severity of wheat blast disease in M2 wheat population. Gamma rays are also being widely used as mutation techniques in an attempt to raise abiotic stress tolerance and, disease resistant crop varieties (Katiyar et al, 2022). Among the 10 entries, BG26M3L4 was found significantly the lowest percent disease incidence (2.4%) and severity (2.0%) than the other tested lines at 80 DAS.…”

“…Therefore, mutation breeding is becoming more popular among breeders and scientists. The use of gamma radiation from radioactive cobalt (60Co) is common; plant varieties with pathogen and disease resistance have been created using induced mutagenesis (Ikram et al, 2010;Katiyar et al, 2022). Bhuiyan et al (2022) observed high values of heritability and genetic advance with high genotypic coefficient of variance (GCV) for plant height, branch number, pod number and yield in irradiated (250 Gy) soybean plants of M4 population.…”

This research is conducted for comparison of an eco-friendly gamma radiation method and chemical fungicidal spray in reducing wheat blast incidence and severity in BINA under both artificial and natural conditions during 2019-2022. Wheat blast infection occurred on the leaves, spikes and newly emerged heads contained typical eye shaped blast symptoms. Magnaporthe oryzae Triticum (MoT), a causal agent of wheat blast was isolated by tissue panting method, cultured on OAT medium at 30 ±10C, confirmed by PCR amplified with universal MoT3 primer pairs that resulted 361 bp. The MoT inoculated (@ 5x106 CFU/mL) wheat plants successfully developed blast symptoms after 16 days in four tested wheat varieties/germplasm. An in vitro evaluation of five chemical fungicides was done against MoT where Nativo and Filia completely inhibited (100%) its radial mycelial growth. A total three spray, combination of half doses of Nativo + Filia [(0.3g + 1mL)/L] at 10 days intervals starting from one week of pre-heading or critical stage significantly reduced wheat blast incidence and severity in both artificially inoculated and natural conditions. Gamma radiated M3 population of wheat vars. also showed better performance in reduction of blast severity. Among the four doses of gamma radiation, 300 Gy significantly showed the better performance in reducing blast disease incidence and severity on wheat var. BG 26. Although combined fungicidal spray treatment (TF) significantly reduced 93.1% DI and 94.3 % DS in var. BG26 over control, but the highest percent reduction of wheat blast incidence (97.7%) and severity (98.4%) was observed on gamma irradiated (300 Gy) M3 line (BG26M3L4) under natural condition indicating gamma radiation brought a change in the genetic level positive for developing source of resistance against wheat blast. Moreover, gamma irradiated M3 line BG26M3L4 increased higher vegetative traits / yield than the combined fungicidal spray indicating gamma radiation might be a good replacement of chemical fungicides for management of blast of wheat.
