Morphological and biochemical responses of Oryza sativa L. (cultivar MR219) to ion beam irradiation
It is demonstrated that low doses of ion beam have a stimulating effect on the height, root length, and fresh weight of the plantlets but not on the number of leaves, while doses higher than 10 Gy caused reductions in all the morphological parameters studied as compared to the control samples.
Detection of Changes in DNA Methylation Induced by Low-Energy Ion Implantation in Arabidopsis thaliana
Changes in DNA methylation in Arabidopsis thaliana plants grown from seeds implanted with low-energy N+ and Ar+ ions are evaluated and a comparison of polymorphisms seen in N+ ion-implanted, Ar+ ion/cm2, and control DNA demonstrated that the species of incident ion influenced the resultingDNA methylation pattern.
Analysis of ROP signaling in the leaf epidermis of mutant tomato with low-energy ion beam.
This study revealed a link between the low-energy ion beam and the ROP GTPase signaling pathway in tomato and suggested a new mechanism for mutations following low- energy ion beam implantation.


The Elementary Study on the Physiological Effect Variation of the Arabidopsis thaliana Implanted by the Low Energy Ion Beam
The results revealed that the germination rate-dose curve falls at first, then rise and fall at last, and the characteristics of the injury rates of the nutrient organs were down at first and then up, in addition, the differences of the different dose were evident.
Biochemistry and Genetic Analysis of Bioeffects of Low Energy N+ Implantation and Y-Radiation on Arabidopsis thaliana
Results indicated that the mutagenic effects of both treatments of Arabidopsis thaliana were inheritable and the ratio of individual plant variation between the two treatments was remarkably different.
Comparative Study on Effects of Low Energy N+ Implantation and γ-ray Radiation on Heredity and Development of Arabidopsis Thaliana
In order to compare the contemporary and genetic variation effect on Arabidopsis thaliana treated with N+ implantation and ?-ray radiation, the authors did some statistical comparison on the
Study of Biological Effects of Low Energy Ion Implantation on Tomato and Radish Breeding
Biological effects of 30 keV low energy nitrogen ion implantation on the seeds of five types of tomato and one type of radish were investigated. Results showed that low energy ions have different
Analysis of mutations induced by carbon ions in Arabidopsis thaliana.
The results indicated that carbon-ion-induced mutations are most likely nulls and that the induced rearrangements may arise through a unique mechanism, indicating that accelerated ions are a useful mutagen for both forward and reverse genetics for plants.
Biological effect on sugar beet seeds induced by ion implantation
Through experimental analysis of peroxidase isozyme in the leaves of sugar beets, it has been verified that the enzyme activity of dry sugar beet seeds is closely connected with the doses of N+ ion
Biological effects of protons targeted to different ranges in Arabidopsis seeds
Radiation-induced damage produced at different ranges in Arabidopsis seeds results in different fluence-response curves with water-imbibed seeds being more sensitive to proton irradiation than dry seeds.
Mutation rate and novel tt mutants of Arabidopsis thaliana induced by carbon ions.
The isolation of novel mutants and the high mutation rate suggest that ion particles can be used as a valuable mutagen for plant genetics.
AFLP Analysis of Arabidopsis Thaliana Treated by Low-Energy Ion Beam
The mutagenic effects of ion implantation on arabidopsis thaliana were analyzed using an amplified fragment length polymorphism (AFLP) fingerprinting and sequence analysis of variant DNA fragments indicated that the transformation of bases appeared to be the dominant type of mutations induced by ion implants.
Biological response of Arabidopsis seed to MeV proton irradiation at different region of its embryo
The experimental results showed that both the germination and survival rates decrease while increasing ion fluence, and the fluence-response curve for different damaged region of the embryo has different characters.
