Introduction insertional mutagenesis t dna insertional mutagen arabidopsis book in arabidopsis can be conveniently accomplished either by agrobacterium mediated t- dna transformation, or by transposable element mobilization.

An advantage of using t- dnas as the insertional mutagen, as opposed to transposons ( martienssen, t dna insertional mutagen arabidopsis book 1998; wisman et al. , 1998), is that t- t dna insertional mutagen arabidopsis book dna insertions will not transpose subsequent to integration within the genome and are therefore chemically and physically stable through multiple generations. The mobility of transposons is not necessarily a bad. We investigated the potential of the agrobacterium tumefaciens t- dna as an insertional mutagen in arabidopsis thaliana. Arabidopsis lines transformed with different t- dna vectors were generated using a leaf disc infection procedure adapted for efficient selection on either kanamycin or hygromycin medium. Recently, a number of mutant gene loci in the arabidopsis t dna insertional mutagen arabidopsis book thaliana plant genome have t dna insertional mutagen arabidopsis book been identified t dna insertional mutagen arabidopsis book through insertional mutagenesis.
