Gene Transfer in Plants Virulent strains of Agrobacterium contain large Ti-plasmids, which are responsible for the DNA transfer and subsequent disease symptoms. It has been shown that Ti-plasmids contain two sets of sequence necessary for gene transfer three sets of sequence necessary for gene transfer four sets of sequence necessary for gene transfer one set of sequence necessary for gene transfer two sets of sequence necessary for gene transfer three sets of sequence necessary for gene transfer four sets of sequence necessary for gene transfer one set of sequence necessary for gene transfer ANSWER DOWNLOAD EXAMIANS APP
