Abstract
The present invention relates to a method of imparting pathogen resistance to plants. This involves applying a hypersensitive response elicitor polypeptide or protein in a non-infectious form to a plant seed under conditions where the polypeptide or protein contacts cells of the plant seed. The present invention is also directed to a pathogen resistance imparting plant seed. Alternatively, transgenic plant seeds containing a DNA molecule encoding a hypersensitive response elicitor polypeptide or protein can be planted in soil and a plant can be propagated from the planted seed under conditions effective to impart pathogen resistance to the plant.
Claims36
A method of producing plant seeds which impart pathogen resistance to plants grown from the seed, said method comprising:
- applying a hypersensitive response elicitor polypeptide or protein in a non-infectious form to plant seeds under conditions effective to impart pathogen resistance to plants grown from the seeds, wherein the hypersynsetive response elicitor is protease sensitive and heat stable at 100° C.
A pathogen-resistance imparting plant seed to which a non-infectious hypersensitive response elicitor polypeptide or protein has been applied, wherein the application of said non-infectious hypersensitive response elicitor polypeptide or protein imparts pathogen-resistance to a plant grown from said plant seed, wherin the hypersensetive response elicitor is protease sensitive and heat stable at 100° C.
