Gene trap mutagenesis: a functional genomics approach towards reproductive research

Gene trap mutagenesis: a functional genomics approach towards reproductive research.

We have entered a new era of genomics in biomedical research with the availability of genome-wide sequences and expression data, resulting in the identification of a huge number of novel reproductive genes. The challenge we are facing today is how to determine the function of those novel and known genes and their roles in normal reproductive physiology, such as gamete production, pregnancy and ...

TILLING. Traditional mutagenesis meets functional genomics.

Most of the genes of an organism are known from sequence, but most of the phenotypes are obscure. Thus, reverse genetics has become an important goal for many biologists. However, reverse-genetic methodologies are not similarly applicable to all organisms. In the general strategy for reverse genetics that we call TILLING (for Targeting Induced Local Lesions in Genomes), traditional chemical mut...

Tnt1 retrotransposon mutagenesis: a tool for soybean functional genomics.

Insertional mutagenesis is a powerful tool for determining gene function in both model and crop plant species. Tnt1, the transposable element of tobacco (Nicotiana tabacum) cell type 1, is a retrotransposon that replicates via an RNA copy that is reverse transcribed and integrated elsewhere in the plant genome. Based on studies in a variety of plants, Tnt1 appears to be inactive in normal plant...
