“…In another report the higher efficiency of lower dose of gamma rays could be described to the fact that biological damage (seedling injury, lethality and sterility) increased with increase in dose at faster rate than the mutations. Inhibition effect by gamma-irradiation may be related to auxin and DNA biogenesis in a relationship which showed that auxin required for the formation of DNA and radiation block occurring in the formation of auxin and nucleic acid synthesis (Momiyama et al, 1999;Krasaechai and Yu, 2009). Growth and development in plants do not advance at invariable rates through time.…”

“…Seeds in the M1 generation were harvested and cultivated for M2 generations. Seeds and buds of various local flowers such as petunia, rose, gerbera and chrysanthemum were bombarded by nitrogen ion beams at energies of 30 -60 keV and fluences of 1 × 10 16 -5 × 10 17 ions/cm 2 in vacuum [16]. It was also observed that the pigment of the seat coat and pericarp were not purple as was found in the wild type (Fig.…”

MeV-ion beam has long been applied to research and applications in biology for many decades as highly energetic ions are undoubtedly able to interact directly with biomolecules to cause biological changes. However, low-energy ion beam at tens of keV and even lower has also been found to have significant biological effects on living materials. The finding has led to applications of ion-beam induced mutation and gene transfer. From the theoretical point of view, the low-energy ion beam effects on biology are difficult to understand since the ion range is so short that the ions can hardly directly interact with the key biological molecules for the changes. This talk introduces interesting aspects of low-energy ion beam biology, including basis of ion beam biotechnology and recent developments achieved in Chiang Mai University in relevant applications such as mutation and gene transfer and investigations on mechanisms involved in the low-energy ion interaction with biological matter such as eV-keV ion beam bombardments of naked DNA and the cell envelopes.

“…In the early stages of assessing radiation's ability to generate mutations, various radiobiological measures are commonly employed. Mutagenic radiations have proven to be especially useful in breeding programs, particularly in flowering crops (Krasaechai et al, 2009) Gamma radiation can alter physiological characteristics (Kiong et al, 2008). As a result of the low genetic variability among current plant genotypes, mutation induction has become a well-established strategy in plant breeding, and a new era of crop development has begun, allowing for the improvement of cultivars in specific key qualities, while enhancing existing germplasm (Irfaq and Nawab, 2001).…”

Gamma irradiation-induced mutagenesis has been utilized to improve many genotypes of crop species. Mutation induction has been identified as a significant method for the production of genetic variation in flowering plants. Hence, a series of experiments were conducted in a completely randomized design at the University of Colombo Institute for Agro-technology and Rural Sciences, Hambantota, Sri Lanka, to evaluate the influence of gamma rays on the mutagenicity of Acalypha hispida. The rooted cuttings were subjected to various dosages of Cobalt-60 gamma irradiation, including 0, 20, 25, 30, 35, and 40 Gy. Based on the findings, a second experiment was carried out in which the plants were exposed to 0, 45, 50, 55, 60, and 65 Gy gamma irradiation dosages. Treated plants were maintained inside a shade net house (30% shade) and morphological changes in plants, survival %, plant height, number of leaves, inflorescence length, and mutation % were recorded. Plants that showed improved characters were multiplied and observed the character expression in the second generation. Further, attempts were made to combine the improved characters into a single plant. There were significant differences in plant height and number of leaves but not in survival % and inflorescence length in experiment one. Further, a significant difference was observed in measured variables survival %, plant height, number of leaves, and inflorescence length in experiment two. A gradual reduction was observed in survival percentage, plant height and inflorescence length with the increase in gamma irradiation dose. Treated plants showed narrowed and malformed leaves but those were not persisted and discontinued. But, irradiated plants produced colour changed (pink and white), partial and no blooming inflorescences which was persisted in the second generation too. Hence, it could be stated that treating the A. hispida plants with gamma radiation has the potential to create mutation in plants.
