Characterization of T-DNA Insertion Sites in Arabidopsis thaliana and the Implications for Saturation Mutagenesis
"... A key component of a sound functional genomics infrastructure is the availability of a knockout mutant for every gene in the genome. A fruitful approach to systematically knockingout genes in the plant Arabidopsis thaliana has been the use of transferred-DNA (T-DNA) from Agrobacterium tumefaciens as ..."

as an insertional mutagen. One of the assumptions underlying the use of T-DNA as a mutagen is that the insertion of these DNA elements into the Arabidopsis genome occurs at randomly selected locations. We have directly investigated the distribution of T-DNA insertions sites in populations of transformed Arabidopsis
Groups involved:
"... Objectives and assessment of the project The objective of this project was to develop a biological and bioinformatic resource making it possible to obtain data of genomic sequences which flank the ADN-T of the mutants affected in genes of selected sequences and thus to facilitate their identificatio ..."

their identifications. These genomic labels are also named FST for "Flanking Sequence Tag". This project based on a first biological resource: a collection of mutants of T-DNA insertion of Arabidopsis thaliana generated by the INRA-GAP of Versailles, composed of 55 000 primary transforming plants and managed
