INCREASING HOST PLANT SUSCEPTIBILITY TO ACROBACTERIUM INFECTION BY OVEREXPRESSION OF THE ARABIDOPSIS VIP1 GENE

摘要

The present invention is directed to methods and compositions which employ anArabidopsis VIP1 gene or VIP1-like gene from another plant species forpurposes of increasing host plant susceptibility to Agrobacterium infection.Methods for increasing susceptibility of a host to Agrobacterium infection andmethods for improving Agrobacterium-mediatedgene transfer are provided. Alsoprovided are chimeric genes and expression vectors that, upon introductioninto a plant cell, enable the plant cell to become more susceptible toAgrobacterium infection and thus better transformed via Agrobacterium-mediatedgene transfer. Transgenic plant cells and plants regenerated therefrom whichoverexpress a VIP1 or VIP1 -like gene are also provided.
