Patterns of gene action in plant development revealed by enhancer trap and gene trap transposable elements.
The crucifer Arabidopsis thaliana has been used widely as a model organism for the study of plant development. We describe here the development of an efficient insertional mutagenesis system in Arabidopsis that permits identification of genes by their patterns of expression during development. Transposable elements of the Ac/Ds system carrying the GUS reporter gene have been designed to act as ...
متن کاملA gene trap approach in Xenopus
The frog transgenesis technique ultimately promises to make mutagenesis possible through random insertion of plasmid DNA into the genome. This study was undertaken to evaluate whether a gene trap approach combined with transgenesis would be appropriate for performing insertional mutagenesis in Xenopus embryos. Firstly, we confirmed that the transgenic technique results in stable integration int...
متن کاملThe International Gene Trap Consortium Website: a portal to all publicly available gene trap cell lines in mouse
Gene trapping is a method of generating murine embryonic stem (ES) cell lines containing insertional mutations in known and novel genes. A number of international groups have used this approach to create sizeable public cell line repositories available to the scientific community for the generation of mutant mouse strains. The major gene trapping groups worldwide have recently joined together t...
متن کاملEstablishment of gene-trap and enhancer-trap systems in the moss Physcomitrella patens.
Because of its simple body plan and ease of gene knockout and allele replacement, the moss Physcomitrella patens is often used as a model system for studies in plant physiology and developmental biology. Gene-trap and enhancer-trap systems are useful techniques for cloning genes and enhancers that function in specific tissues or cells. Additionally, these systems are convenient for obtaining mo...
متن کاملGene regulation by substoichiometric heterocomplex formation of undecameric TRAP and trimeric anti-TRAP.
The control of tryptophan production in Bacillus is a paradigmatic example of gene regulation involving the interplay of multiple protein and nucleic acid components. Central to this combinatorial mechanism are the homo-oligomeric proteins TRAP (trp RNA-binding attenuation protein) and anti-TRAP (AT). TRAP forms undecameric rings, and AT assembles into triskelion-shaped trimers. Upon activation...
