Towards the ideal GMP: homologous recombination and marker gene excision.
A mayor aim of biotechnology is the establishment of techniques for the precise manipulation of plant genomes. Two major efforts have been undertaken over the last dozen years, one to set up techniques for site-specific alteration of the plant genome via homologous recombination ("gene targeting") and the other for the removal of selectable marker genes from transgenic plants. Unfortunately, de...
متن کاملan improved homologous recombination method for rapid cloning of the antibody heavy chain gene and its comparison with the homologous recombination and traditional cloning methods
background: the homologous recombination (hr) is one of the conventional cloning methods for the production of recombinant dna. it is a quick method for in vivo dna cloning without using the high cost restriction enzymes. a few modifications in the cloning procedure can increase the efficiency of this method. m aterials and methods: in this study, effect of heating on the rate of the igg1 heavy...
متن کاملCENTRIN2 modulates homologous recombination and nucleotide excision repair in Arabidopsis.
A genetic screen of a population of Arabidopsis thaliana lines exhibiting enhanced somatic homologous recombination yielded a mutant affected in expression of a gene encoding a caltractin-like protein (centrin). The hyperrecombinogenic phenotype could be reproduced using RNA interference (RNAi) technology. Both the original mutant and the RNAi plants exhibited a moderate UV-C sensitivity as wel...
متن کاملDesigning E1 Deleted Adenoviral Vector by Homologous Recombination
Adenoviruses are used extensively to deliver genes into mammalian cells, particularly where there is a requirement for high-level expression of transgene products in cultured cells, or for use as recombinant viral vaccines or in gene therapy. In spite of their usefulness, the construction of adenoviral vectors (AdV) is a cumbersome and lengthy process that is not readily amenable to the generat...
متن کاملNucleotide excision repair and homologous recombination systems commit differentially to the repair of DNA-protein crosslinks.
DNA-protein crosslinks (DPCs)-where proteins are covalently trapped on the DNA strand-block the progression of replication and transcription machineries and hence hamper the faithful transfer of genetic information. However, the repair mechanism of DPCs remains largely elusive. Here we have analyzed the roles of nucleotide excision repair (NER) and homologous recombination (HR) in the repair of...
