Multiple Deoxyribonucleic Acid Polymerases from Quiescent Wheat
Three DNA polymerases (A, B and C) have been purified from the soluble cytoplasm of ungerminated wheat embryos. Mainly on the basis of chromatographic, template-specificity and salt-inhibition evidence, we have characterized the three enzymes. Other physicochemical and enzymic properties are described. From purified mitochondria we have purified a DNA polymerase that behaves like DNA polymerase...
متن کاملDeoxyribonucleic Acid polymerase from wheat embryos.
A soluble DNA-dependent DNA polymerase was extracted from wheat embryos. In vitro, the incorporation of radioactive thymidine triphosphate into acid-insoluble material is dependent upon the presence of the enzyme, all four deoxyribonucleotide triphosphates, Mg(2+), and a DNA template. Incorporation occurs on native, alkali-denatured, and strictly double-stranded DNA. The in vitro synthesized pr...
متن کاملOnset of deoxyribonucleic Acid synthesis in germinating wheat embryos.
Germinating wheat embryos (Triticum vulgare var. Florence) synthesize proteins before the onset of DNA synthesis. The onset of DNA replication occurs at about 15 hours of germination and was shown to depend on proteins synthesized before 9 hours of germination with the use of blasticidin S, a specific inhibitor of protein synthesis. A 10-fold increase in the activity of DNA-dependent DNA polyme...
متن کاملThe Effect of High Temperature Treatment on Wheat Streak Mosaic Virus Resistance and Certain Resistance-Related Chemicals in Bread Wheat
Background and Aims: To evaluate the effect of temperature on wheat streak mosaic virus (WSMV) resistance phenotype, through total protein, phenol, and peroxidase activity in bread wheat, a factorial experiment was conducted using Adl-Cross (resistant) and Marvdasht (susceptible) cultivars. Materials and Methods: Results showed that incubation at 32C changed the gene expression for resistance ...
متن کاملTemporally and Genetically Discrete Periods of Wheat Sensitivity to High Temperature
Successive single day transfers of pot-grown wheat to high temperature (35/30°C day/night) replicated controlled environments, from the second node detectable to the milky-ripe growth stages, provides the strongest available evidence that the fertility of wheat can be highly vulnerable to heat stress during two discrete peak periods of susceptibility: early booting [decimal growth stage (GS) 41...
