Method for producing disease resistant plant with thionin gene from Avena sativa

A method for producing a transgenic plant, comprising the steps of:

• constructing an expression vector comprising an expression cassette comprising a thionin gene from Avena sativa, the expression cassette expressing the thionin gene;
• transforming a plant cell with the expression vector to produce a transformed plant cell;
• and
• regenerating the transgenic plant from the transformed plant cell;
• wherein the transgenic plant has enhanced resistance to at least one disease compared to non-transgenic plants, wherein the disease is a disease caused by a plant pathogenic filamentous fungus, wherein the disease is late blight of potato and wherein the transgenic plant is a plant of the family Solanaceae.

A method for conferring resistance to at least one disease to a plant, comprising the steps of:

• transforming a plant cell with an expression vector which comprises an expression cassette comprising a thionin gene from Avena sativa, the expression cassette expressing the thionin gene to produce a transformed plant cell;
• and
• regenerating a transgenic plant from the transformed plant cell;
• wherein the transgenic plant has enhanced resistance to at least one disease compared to non-transgenic plants, wherein the disease is a disease caused by a plant pathogenic bacterium, wherein the disease is bacterial leaf blight of rice or bacterial seedling blight of rice, and wherein the transgenic plant is a plant of the family Poaceae.
