“…The mutants of several crops have been generated through radiation mutagenesis in the last decade (Encheva et al, 2003;Adekola et al, 2007;Tabosa et al, 2007;Chen et al, 2008;Fu et al, 2008;;Gómez-Pando et al, 2013), including amaranth (Gómez-Pando et al, 2009). Changes were registered for branch number, pedicel length, plant height, life cycle duration, leaf morphology, stem, foliage and seed color, seeds per head, seed size, seed yield, 1000-seed weight, tolerance to pathogens and soil salinity, and chemical composition such as protein and oil content.…”

IntroductionPlants, and particularly the horticulture section, are used by people for food, either as edible products or for culinary ingredients, and for medicinal use or ornamental and aesthetic purposes. They are genetically a very diverse group and play a major role in modern society end economy. Fruits and vegetables are important components of traditional food, but are also central to healthy diets of modern urban populations (

“…The root length and seedling height of generation M 1 decreased proportionally to dosage amount (Table 1), as reported for other crops [14,17] and the identification of irradiation dosage limit of 350 Gy for cv. Pasankalla [18]. One peculiar response of quinoa to the damage of irradiation is the longer time for true leaf formation and the absence of them at high dose finishing with the death of the seedlings.…”

Quinoa (Chenopodium quinoa Willd.) is a staple food produced mainly by small-scale subsistence farmers in Peru's highland. Dry seeds (cv. Pasankalla) were irradiated with doses of 150 Gy, 250 Gy and 350 Gy. In the M 1 generation, the germination process was delayed with increasing radiation dose; seedling height, root length and leaf development were most reduced at 250 Gy and at 350 Gy, no plants survived. In M 2 , the maximum spectrum of chlorophyll mutations corresponded to 150 Gy and the maximum frequency to 250 Gy. The chlorine mutation was predominant, followed by xantha. Changes were registered for branch number, pedicel length, plant height, life-cycle duration, stem and foliage colour, and leaf morphology at the two doses, with improvements in plant type. More than one mutation per plant was found, especially at 250 Gy. In M 3 , the same spectrum of mutations was observed, along with a valuable change in grain colour.

“…Results reported here are therefore consistent with previous findings 37 in rice where induced mutants had SSR profiles identical to their parents. Any possible detectable variations due to outcrossing, which results in SSR polymorphisms, could then have been interpreted as equivalent to the results found for salt-tolerant sorghum, where SSRs detected genetic changes induced by gamma rays 38 but subsequently interpreted as resulting from outcrossing.…”

Abstract:Seeds from an inbred Vigna unguiculata (cowpea) cultivar were gamma-irradiated with a dose of 180 Gy in order to identify and characterize possible mutations. Three techniques, ie, random amplified polymorphic DNA, microsatellites, and representational difference analysis, were used to characterize possible DNA variation among the mutants and nonirradiated control plants both immediately after irradiation and in subsequent generations. A large portion of putative radiation-induced genome changes had significant similarities to chloroplast sequences. The frequency of mutation at three of these isolated polymorphic regions with chloroplast similarity was further determined by polymerase chain reaction screening using a large number of individual parental, M1, and M2 plants. Analysis of these sequences indicated that the rate at which various regions of the genome is mutated in irradiation experiments differs significantly and also that mutations have variable "repair" rates. Furthermore, regions of the nuclear DNA derived from the chloroplast genome are highly susceptible to modification by radiation treatment. Overall, data have provided detailed information on the effects of gamma irradiation on the cowpea genome and about the ability of the plant to repair these genome changes in subsequent plant generations.
