Transgenesis in C. elegans.
The ability to manipulate the genome of organisms at will is perhaps the single most useful ability for the study of biological systems. Techniques for the generation of transgenics in the nematode Caenorhabditis elegans became available in the late 1980s. Since then, improvements to the original approach have been made to address specific limitations with transgene expression, expand on the re...
متن کاملMos1-Mediated Transgenesis to Probe Consequences of Single Gene Mutations in Variation-Rich Isolates of Caenorhabditis elegans
Caenorhabditis elegans, especially the N2 isolate, is an invaluable biological model system. Numerous additional natural C. elegans isolates have been shown to have unexpected genotypic and phenotypic variations which has encouraged researchers to use next generation sequencing methodology to develop a more complete picture of genotypic variations among the isolates. To understand the phenotypi...
متن کاملA Genome-Wide Collection of Mos1 Transposon Insertion Mutants for the C. elegans Research Community
Methods that use homologous recombination to engineer the genome of C. elegans commonly use strains carrying specific insertions of the heterologous transposon Mos1. A large collection of known Mos1 insertion alleles would therefore be of general interest to the C. elegans research community. We describe here the optimization of a semi-automated methodology for the construction of a substantial...
متن کاملUbiquitin-mediated pathways in C. elegans.
Ubiquitin is a highly conserved 76 amino acid polypeptide, which is covalently attached to target proteins to signal their degradation by the 26S proteasome or to modify their function or localization. Regulated protein degradation, which is associated with many dynamic cellular processes, occurs predominantly via the ubiquitin-proteasome system. Ubiquitin is conjugated to target proteins throu...
متن کاملTol2-mediated transgenesis in tilapia (Oreochromis niloticus).
The Nile tilapia (Oreochromis niloticus) is an important species in aquaculture and an excellent model system for laboratory studies. Functional genetic analysis using this species has been difficult because existing methods for producing transgenics are inefficient. Here we show that the Tol2 transposon system can be used to create transgenic tilapia with high efficiency. We constructed a line...
