In mutation breeding programs, the plant breeders are focused to identify the individuals from a population that have an allelic variation of a gene. In contrast to forward genetic, reverse genetic is more popular to detect the function of a gene. Water in the cell accumulates energy initially and facilitates the production of reactive radicals, which oxidize and reduce. Recombination is not responsible to produce new traits itself. Thanks for contributing an answer to Biology Stack Exchange! Chromosome malsegregation and defects in chromatid separation, bridge formation, chromosome exchange, chromosome breakage, and loss of chromosome fragments can be observed after IR treatment [13]. Careers. Global food production is facing a series of challenges, such as rapid population growth, environmental pollution and climate change. Mutation breeding, sometimes referred to as " variation breeding ", is the process of exposing seeds to chemicals, radiation, or enzymes [1] [2] in order to generate mutants with desirable traits to be bred with other cultivars. 10.1016/0969-8043(95)00096-8 There are two main classes of random mutagenesis: (1) physical mutagenesis through x-rays, gamma rays and ultraviolet (UV) radiation. The information obtained from ISSR analysis is more reliable than RAPD to provide supplementary data of the genetic variations of the mutants from the nonoverlapping genome regions [48]. In vitro mutagenesis applications give opportunity to the breeders to select the mutants in a controlled environment. It is also reported by several studies that direct and indirect radiation effects may produce identical reactive intermediates. The natural resources are limited, and due to the natural disasters like sudden and severe abiotic stress factors, excessive floods, etc., the production capacities are changed per year. The quantitatively and qualitatively characterized the mutations induced by acute/chronic gamma ray irradiation in Arabidopsis and these data will aid the understanding of the effects of radiation types and be useful in selecting suitable radiation treatments for mutagenesis.
