The present invention provites a compound having the following structure: 

Diterpenoid compounds imparting stress resistance to plants

The present invention is drawn to a method of conferring resistance to pathogenic fungi on a plant by transformation with a nucleic acid encoding Sarcotoxin 1a operatively linked to a signal peptide, and optionally linked via the hinge region of tobacco chitinase to a plant peptide, and plants thereby obtained.

Pathogen-resistant plants transformed with a DNA encoding sarcotoxin 1A linked to a signal peptide and a method for production thereof

A method for regulating cell death in a plant, includes the steps of: transforming a plant cell with a polynucleotide containing a gene encoding DS9 or a homologue thereof or a part of the gene; and redifferentiating the transgenic plant cell to obtain a plant. The DS9 or the homologue thereof is an ATP-dependent Zn-type metalloprotease. The polynucleotide decreases or increases production of the ATP-dependent Zn-type metalloprotease in the plant cell, whereby cell death of a cell in the plant is promoted or suppressed.

Method for regulating cell death

The present invention provides a stress resistant plant in which a cell death suppressing gene is introduced.

Stress resistant plant in which cell death suppressing gene is introduced and method for producing the same

A plant exhibiting resistance to at least one disease is provided. The plant includes an expression cassette including a thionin gene from,, which is capable of expressing the thionin protein. A method for producing the plant is also provided. The method includes the steps of constructing an expression vector containing an expression cassette including a thionin from,gene, which is capable of expressing the thionin protein, transforming a plant cell with the expression vector, and regenerating a plant from the transformed plant cell. The plant exhibits resistance to at least one disease such as a disease caused by a plant pathogenic bacterium (e.g., a bacterium causing bacterial leaf blight of rice or a bacterium causing bacterial seedling blight of rice) or a plant pathogenic filamentous fungus (e.g., a fungus causing late blight of potato). A seed obtained from the above disease resistant plant is also provided.
