Abstract:

Trigonella foemum graecum L was utilized to study the Chlorophyll mutations, mutagenic efficiency and effectiveness by physical mutagen gamma rays and chemical mutagen EMS. The frequency of chlorophyll mutation in M1 & M2 generation were more in gamma treated plants but the mutation spectra and mutagenic efficiency of EMS was higher than gamma. The most efficient mutagens were 0. 02% EMS, 0.06% EMS and 3KR gamma radiation to induce mutation in T. foenum graceum L.

Abstract:

Mutagenesis refers to the process of generation of mutations in DNA molecules, including chromosomal rearrangements and alterations in DNA sequence. The incidence of natural or spontaneous mutation frequency in nature is very low, and it is not sufficient for plant breeding programs to develop new varieties. Mutants were also used for gene function discovery which controls the particular phenotype. Genetic diversity was induced in plants on a good scale through induced mutagenesis programmes, and this helped to improve crops all over the world. Significant efforts have been made to develop ind

Abstract:

Soybean genetic variation improvement is important for the development of superior cultivars. One of the greatest challenges in mutation breeding is random (uncontrolled) nature of induced mutagenesis. Large population requirement for desired mutant selection brings intensive labor. Choice of appropriate mutagen is one of the deciding factors on succession of the mutation breeding program. Physical, chemical, or biological agents are viable alternatives.

Present investigation was undertaken to study the frequency and spectrum of induced viable macromutations employing SA, EMS and gamma radiation in chickpea (Cicer arietinum L.) cultivar Vishwas (Phule G 5). The seeds of chickpea, cultivar Vishwas were treated with three different concentrations / doses of SA (2, 3 and 4 mM), EMS (8, 12 and 16 mM) and gamma radiations (400, 500 and 600 Gy). The mutagen administered seeds were sown in experimental fields to raise M1 progeny. Seeds of M1 plants and control were harvested separately and sown to raise M2 population. The M2 progeny were screened for

Abstract:

DNA copy number variation (CNV) occurs due to deletion or duplication of DNA segments resulting in a different number of copies of a specific DNA-stretch on homologous chromosomes. Implications of CNVs in evolution and development of different diseases have been demonstrated although contribution of environmental factors, such as mutagens, in the origin of CNVs, is poorly understood. In this review, we summarize current knowledge about mutagen-induced CNVs in human, animal and plant cells. Differences in CNV frequencies induced by radiation and chemical mutagens, distribution of CNVs in the ge

Abstract:

Identifying plants with desirable traits among existing plant varieties is the initial and most important step in plant breeding. Plant breeding requires the genetic variation of useful traits for crop improvement or crop betterment. The plant breeding depends upon the genetic variation. In nature, variation occurs mainly as a result of mutation and without it, plant breeding would be impossible. Mutation as a mechanism of creating variability was identified by Hugo de Vries while experimenting on the rediscovery of Mendel’s Law of Inheritance.17 Mutation arises in two ways; First, spontaneous

The data show that rodents immunized with TLV are resistant to mutagen of any origin (chemical, physical, biological) independently of species (rats, mice, gray hamsters, guinea pigs). Exposure of immunized rodents to carcinogens decreased the incidence of tumors, prolonged the mean latency period of tumor development, and decreased the mean tumor weight.

Abstract:

The widespread use of mutagenesis for plant genetic improvement can be explained by a number of factors, including the fact that new varieties can be developed in a shorter time than conventional breeding methods and that transgenesis is more difficult to re-engineer. Gamma rays are physical mutagens that are often used in plant mutagenesis techniques and are safe for human health because there is no environmental risk in the induced generations. The method used in this paper is by grouping articles according to their relevance to the subject and year of research, and finally managing the expl

Gamma rays as a type of ionizing radiation constitute a physical mutagen that induces mutations and could be effectively used in plant breeding. To compare the effects of gamma and ionizing irradiation according to exposure time in common wheat (Keumgang, IT 213100), seeds were exposed to 60Co gamma rays at different dose rates. To evaluate the amount of free radical content, we used electron spin resonance spectroscopy. Significantly more free radicals were generated in the case of long-term compared with short-term gamma-ray exposure at the same dose of radiation. Under short-term exposure,
