Abstract:
:The creation of transgenic plants has brought significant advances to light in plant biotechnology. However, in spite of the fact that transgenic plants are beginning to be grown widely, controlled transgene integration into a pre-determined site remains to be achieved. Here we suggest two alternative approaches for gene targeting in plants: manipulating the host and donor sequence, and targeting during active homologous recombination stages.
