Morphological and chromosomal abnormalities in gamma radiation-induced mutagenized faba bean genotypes.
TL;DR: The gamma radiation decreased the seedling emergence and induced a wide range of morphological and chromosomal abnormalities in faba bean.
Journal ArticleDOI
Induction of phenotypic diversity in mutagenized population of lentil (Lens culinaris Medik) by using heavy metal.
TL;DR: In this paper, the lentil seeds were mutagenized with different doses (5, 10, 15, 20, 20 and 25 ppm) of lead and cadmium nitrate.
Journal ArticleDOI
Generation of mutant lines of Nigella sativa L. by induced mutagenesis for improved seed yield
TL;DR: It is concluded that ethyl methane sulphonate, gamma rays and their different combinations can be used efficiently to improve N. sativa and to induce genetic variability in this medicinal plant.
Journal ArticleDOI
An overview on genotoxicity of heavy metal in a spice crop (Capsicum annuum L.) in respect to cyto-morphological behaviour
TL;DR: It was concluded that lower concentrations of metal did not significantly affect the cyto-morphology of Capsicum, while higher concentrations of lead nitrate were found to be more mutagenic and genotoxic.

TL;DR: Under field conditions, significant differences were noticed with respect to plant height, number of nodes in the orthotropic stem, and number of branches of the M1 mutant (NaN3-treated) plants compared to the non-mutant plants.

DNA polymorphisms amplified by arbitrary primers are useful as genetic markers
TL;DR: A new DNA polymorphism assay based on the amplification of random DNA segments with single primers of arbitrary nucleotide sequence is described, suggesting that these polymorphisms be called RAPD markers, after Random Amplified Polymorphic DNA.

Antioxidant activities of red pepper (Capsicum annuum) pericarp and seed extracts
Ki Hyeon Sim,Han Young Sil +1 more
TL;DR: In this paper, the antioxidant properties of red pepper (Capsicum annuum, L.) pericarp and red pepper seed extracts were evaluated by various antioxidant assays, including 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging, superoxide dismutase (SOD) activity and reducing power, along with the determination of total phenolic and flavonoid contents.

TL;DR: The F3 fraction, rich in peptides, inhibited the growth of yeasts Saccharomyces cerevisiae and caused several morphological changes in different yeasts, such as cell wall disorganization, bud formation as well as the formation of pseudohyphae.

Effect of ethyl methanesulfonate on the fertility of barley.
M. Sato,Horst Gaul +1 more
TL;DR: The studies reveal that the sterility induced is heritable and suggest that, in contrast to the effects of X-rays, a large part of sterility has a diplontic and not a haplontic nature.

Studies on mutagenic effectiveness and efficiency of gamma rays and its effect on quantitative traits in finger millet (Eleusine coracana L. Gaertn)
TL;DR: In M2 generation, the mutagenic treatments were effective in inducing various types of chlorophyll and morphological macro mutants, few of those show significant change in flowering, maturity and plant height character and few of them have good breeding value.
