Claims23
A compound of general formula I:
- or salt thereof,
- wherein R1 is C, N or S;
- wherein R2 and R4 are each independently a hydrogen, oxygen, sulfide, alkyl, hydroxide, alkoxide, amino, mercaptor, alkyl sulfide, thionyl, halo, cyano, nitro or carboxylate;
- wherein at least one of R3 and R9 is a halogen and wherein R3 and R9 can be a hydrogen, alkyl, oxygen, halo or mercapto;
- wherein A1 is selected from the group consisting of a carbon, nitrogen, oxygen and sulfur, where in A2 is nitrogen, wherein when A1 or A2 is a nitrogen R5, R6, R7 or R8 is a hydrogen, wherein when A1 comprises a carbon, A1 comprises —COOH or a carboxyalkyl and wherein a structure of compound I induces modulation of a resistance gene, a gene from Table I or induces pathogen or disease resistance in a plant.
(canceled)
A method of inducing pathogen resistance in a plant comprising contacting the plant with a compound having the general formula I:
- or salt thereof,
- wherein R1 is C, N or S;
- wherein R2 and R4 are each independently a hydrogen, oxygen, sulfide, alkyl, hydroxide, alkoxide, amino, mercaptor, alkyl sulfide, thionyl, halo, cyano, nitro or carboxylate;
- wherein at least one of R3 and R9 is a halogen and wherein R3 and R9 can be a hydrogen, alkyl, oxygen, halo or mercapto;
- wherein A1 and A2 are each independently a carbon, nitrogen, oxygen or sulfur, wherein when A1 or A2 is a nitrogen, R5, R6, R7 or R8 is a hydrogen, wherein when A1 comprises a carbon, A1 comprises —COOH or a carboxyalkyl and A3 is —NHR10 wherein R10 is —H, or an alkyl and wherein a structure of compound I induces modulation of a resistance gene, a gene from Table I or induces pathogen or disease resistance in a plant.
A method of inducing pathogen resistance in a plant comprising contacting the plant with a composition that causes increased transcription of a LURP gene member.
(canceled)
A composition of comprising a 3-, 4-, or 5-chloroanthranilic acid and a carrier.
A method of inducing pathogen resistance in a plant comprising contacting the plant with a 3-, 4-, or 5-chloroanthranilic acid.
