Genotoxin Induced Mutagenesis in the Model Plant Physcomitrella patens
The moss Physcomitrella patens is unique for the high frequency of homologous recombination, haploid state, and filamentous growth during early stages of the vegetative growth, which makes it an excellent model plant to study DNA damage responses. We used single cell gel electrophoresis (comet) assay to determine kinetics of response to Bleomycin induced DNA oxidative damage and single and doub...
متن کاملExcision repair is required for genotoxin-induced mutagenesis in mammalian cells.
Certain hexavalent chromium [Cr(VI)] compounds are human lung carcinogens. Although much is known about Cr-induced DNA damage, very little is known about mechanisms of Cr(VI) mutagenesis and the role that DNA repair plays in this process. Our goal was to investigate the role of excision repair (ER) pathways in Cr(VI)-mediated mutagenesis in mammalian cells. Repair-proficient Chinese hamster ova...
متن کاملTagged mutagenesis and gene-trap in the moss, Physcomitrella patens by shuttle mutagenesis.
The moss, Physcomitrella patens has been used as a useful material in many fields, because of its simple body plan, ease of gene targeting, and other reasons. Although many mutants have been reported, no method to isolate the corresponding genes was reported. We developed a gene tagging and gene-trap system in P. patens by using the shuttle mutagenesis technique, which has been used in the budd...
متن کاملTransformation of the moss Physcomitrella patens using T-DNA mutagenesis.
In this protocol, the transformation of moss (Physcomitrella patens) protoplasts is performed via Agrobacterium-mediated transfer of T-DNA. Protoplasts are incubated with Agrobacterium and acetoseringone in regeneration medium. They are then washed and plated on antibiotic-containing medium to select for T-DNA insertion in stable transformants. The transformation rate for this protocol is typic...
متن کاملA new moss genetics: targeted mutagenesis in Physcomitrella patens.
The potential of moss as a model system to study plant biology is associated with their relatively simple developmental pattern that nevertheless resembles the basic organization of the body plan of land plants, the direct access to cell-lineage analysis, their similar responses to plant growth factors and environmental stimuli as those observed in other land plants, and the dominance of the ga...
