“…Several studies have focused on the biological effects of ionizing radiation on ornamental plant seeds. Yu et al (2016) confirmed experimentally that carbon ion beam irradiation is effective in inducing genomic variations of geranium (Pelargonium × hortorum, Bailey), which induces changes in the flower colour and anthocyanin accumulation in the plant. Kim et al (2019) reported 25-Gy gamma irradiation facilitated the growth of creeping bentgrass, which increased the shoot length, shoot width, root length, leaf blade length, sheath length, and fresh weight compared with control groups.…”

“…Mutation breeding induced by ionizing radiation has been proven to increase plant chromosomal variation, cause changes in morphology, physiology, and biochemistry, and breed new varieties in a short cycle ( Su et al, 2019 ). Meanwhile, mutation breeding by ionizing radiation can also be widely used in the quality improvement of flowering plants ( Yu et al, 2016 ). The phenotypes of these new flower varieties show many characteristics such as varied colour, shape, size, and flowering period ( Yu et al, 2016 ; Yamaguchi, 2018 ).…”

Electron beam to target turning X-ray (EBTTX) is an emerging irradiation technology that can potentially accelerate the breeding process of plants. The biological effects of EBTTX irradiation on the two freesia cultivars (the red freesia and the purple freesia) were investigated by establishing an irradiation-mediated mutation breeding protocol. The germination rate, survival rate, plant height, leaf number and area, root number and length of the two freesia cultivars decreased following different irradiation doses (25, 50, 75, and 100-Gy). A high irradiation dose exhibited stronger inhibition effects on these plant growth parameters, and the survival rate of the two freesia cultivars was 0.00% following the 100-Gy irradiation treatment. The median lethal dose (LD50) based on survival rates was 54.28-Gy for the red freesia and 60.11-Gy for the purple freesia. The flowering rate, flower number, and pollen vigor were significantly decreased by irradiation treatment. At 75-Gy irradiation, the flowering rate, flower number and pollen viability of the two varieties reached the minimum, exhibiting strong inhibitory effects. Meanwhile, 75-Gy irradiation significantly decreased the chlorophyll content and increased the malondialdehyde (MDA) content of the two freesia cultivars. Furthermore, as the irradiation dose increased, the changes in the micro-morphology of the leaf epidermis and pollen gradually increased according to a scanning electron microscope (SEM) analysis. These results are expected to provide useful information for the mutation breeding of different freesia cultivars and other flowering plants.

“…Hence, the heavy-ion beam provides a higher relative biological effectiveness (RBE) than the low LET radiation (Tanaka et al, 2010 ; Kazama et al, 2011 ; Nagata et al, 2016 ; Zhou et al, 2016 ). For plant mutation breeding, various mutant populations have been generated by heavy-ion beam irradiation: for instance, those of Arabidopsis thaliana (Tanaka et al, 1997 , 2002 ), Lotus japonicus (Oka-Kira et al, 2005 ; Luo et al, 2016 ), Rice ( Oryza sativa L.) (Ishikawa et al, 2012 ; Phanchaisri et al, 2012 ; Morita et al, 2017 ), Petunia ( Petunia hybrid ), Hase et al, 2010 ), Tricyrtis hirta (Nakano et al, 2010 ), Chrysanthemum (Matsumura et al, 2010 ), Wandering Jew (He et al, 2011 ), Geranium (Yu et al, 2016 ), and so on.…”

Heavy-ion beam irradiation is one of the principal methods used to create mutants in plants. Research on mutagenic effects and molecular mechanisms of radiation is an important subject that is multi-disciplinary. Here, we re-sequenced 11 mutagenesis progeny (M3) Arabidopsis thaliana lines derived from carbon-ion beam (CIB) irradiation, and subsequently focused on substitutions and small insertion-deletion (INDELs). We found that CIB induced more substitutions (320) than INDELs (124). Meanwhile, the single base INDELs were more prevalent than those in large size (≥2 bp). In details, the detected substitutions showed an obvious bias of C > T transitions, by activating the formation of covalent linkages between neighboring pyrimidine residues in the DNA sequence. An A and T bias was observed among the single base INDELs, in which most of these were induced by replication slippage at either the homopolymer or polynucleotide repeat regions. The mutation rate of 200-Gy CIB irradiation was estimated as 3.37 × 10−7 per site. Different from previous researches which mainly focused on the phenotype, chromosome aberration, genetic polymorphism, or sequencing analysis of specific genes only, our study revealed genome-wide molecular profile and rate of mutations induced by CIB irradiation. We hope our data could provide valuable clues for explaining the potential mechanism of plant mutation breeding by CIB irradiation.
