Involvement of a vitronectin-like protein in attachment of Agrobacterium tumefaciens to carrot suspension culture cells.

Abstract excerpt

Infections of dicotyledonous plants by Agrobacterium tumefaciens result in the formation of crown gall tumors. Attachment of the bacteria to plant host cells is required for tumor formation. Human vitronectin and antivitronectin antibodies both inhibited the binding of A. tumefaciens to carrot cells. Wild-type bacteria are able to bind radioactive vitronectin; nonattaching mutants showed a reduction in the...
