Effect of Chemical Mutagen on Some Biochemical Properties of Stevia rebaudiana Bertoni

Induced mutagenesis causes an increase variation of some products with limited genetic resources. In this study, the antioxidant enzymes activity, biochemical properties and glycoside content of Stevia were assessed by EMS (chemical mutagen) based on two experiments as factorial with completely randomized design with three replications. The results of the first experiment showed that some prope...

Genetic and Non-Genetic Factors in Pigmentation of Neurospora Crassa.

HE biochemical genetics of carotenoid pigments has been studied in the T tomato ( LEROSEN et al. 1941 ; MACKINNEY and JENKINS 1949 ; PORTER and LINCOLN 1950), corn (MANGELSDORF and FRAPS 1931) and red yeast (BONNER et al. 1946). HAXO (1949) worked out the carotenoid components of the wild type Neurospora. The present paper deals with genetic and biochemical studies of a modifier system for pigm...

Peptides from the calcitonin genes: molecular genetics, structure and function.

PCR in forensic genetics.

Since the introduction in the mid-1980s of analyses of minisatellites for DNA analyses, a revolution has taken place in forensic genetics. The subsequent invention of the PCR made it possible to develop forensic genetics tools that allow both very informative routine investigations and still more and more advanced, special investigations in cases concerning crime, paternity, relationship, disas...

Effects of Lichenic Extracts (Hypogymnia physodes, Ramalina polymorpha and Usnea florida) on Human Blood Cells: Cytogenetic and Biochemical Study

Several lichen species have been used for medicinal purposes throughout the ages, and they were reported to be effective in the treatment of different disorders including tuberculosis, hemorrhoids, ulcer, dysentery and cancer. It is revealed that they may be easily accessible sources of natural drugs that could be used as a possible food supplement or in pharmaceutical industry after their safe...

Evaluation of some physiological and biochemical characteristics of bread wheat (Triticum aestivum L.) genotypes under salinity stress

Since about 20% of the world's arable land and 50% of productions in the world are subject to salinity stress, it affects all stages of plant life from germination to seed production. The aim of this study was to investigate the effect of salinity stress on physiological and biochemical characteristics of some wheat cultivars. For this purpose, a factorial experiment was conducted in a complete...
