DNA modification
1.Molecular Genetic Analysis of an Unusual DNA Modification in Streptomyces Lividans
2.A novel DNA modification discovered in Streptomyces lividans is different from DNA methylation. This unusual modification causes wild type S. lividans DNA sensitive to site-specific oxidative double-strand cleavage (Dnd phenotype, DNA degradation).
3.A novel DNA modification discovered in Streptomyces lividans 1326 is different from DNA methylation. This unusual modification causes wild type S. lividans 1326 DNA sensitive to site-specific oxidative double-strand cleavage (Dnd phenotype).
4.Preliminary study revealed that such DNA modification involves incorporation of sulphur. The entire functional dnd cluster, 8.3kb in size, including 3 ORFs-dndA, dndB and dndC was involved in this DNA modification.
5.Isolation and Characterization of Genes Encoding Histone Modification Enzyme and DNA Methyltransferase in Wheat (Triticum Aestivum.L)
6.(1) we discuss Factors of genomic DNA degradation in Braconidae specimen. These factors include high temperature, oxidation and chemic modification. We should douse Braconidae specimen in 100% ethanol with 50mmol/L EDTA.
7.Studies on Fabrication and Surface Modification of Thermoplastic Microfludic Chips and Applications in Chip-based DNA Analysis
8.coli were tested for developing an conjugation system for S. nanchangensis NS3226.A dnd gene cluster, which encodes an unknown modification system for 5 Hvidans 1326 and renders its DNA susceptible to site-specific double-strand DNA cleavage during electrophoresis was conjugated from E. coli into S. nanchangensis NS3226. The total DNA of exoconjugants acquired DNA degradation phenotype during electrophoresis, which suggested that the dnd gene cluster was heterologously expressed.
9.A technique based on a recent modification of the polyerase chain reaction (PCR) was used to amplify random sequences from one pair of wheat near-isogenic lines that differed for a powdery mildew resistance gene(Pm4a) in order to identify the randomly amplified polymorphic DNA(RAPD) markers linked to the gene for resistance to powdery mildew.
