Abstract

Methods and compositions for suppressing gall formation in plant cells induced by Agrobacterium infection are disclosed. The methods involve introducing at least one DNA construct, encoding at least one untranslatable sense-strand RNA and/or double-stranded RNA, into a plant cell. Introduction of these molecules into the plant cell causes the plant cells to become resistant to gall formation.
