The development of SAR is associated with the induction of pathogenesis related ( PR) gene expression. In addition to signaling SAR, SA regulates both basal and R-gene mediated local disease resistance mechanisms. SAR can be induced effectively by exogenous applications of either SA or synthetic functional analogs of SA, 2,6-dichloroisonicotinic acid (INA) and benzo (1,2,3) thiadiazole-7-carbo-thioic acid S-methyl ester (BTH). Exogenous application of SA increases the resistance of tobacco plants to tobacco mosaic virus (TMV). Salicylic acid (SA) is a signaling molecule of the SAR pathway. The induced resistance is typically effective against a wide range of pathogens including those taxonomically unrelated to the SAR inducing organism. SAR can be triggered by infection with certain pathogenic strains. One of the most common inducible defense mechanisms is systemic acquired resistance (SAR).

Plants use a series of physical, preformed chemical and inducible defense mechanisms to protect themselves from pathogen attack. Substitution of Cys 216 residue, essential for oligomer-monomer transition of Arabidopsis NPR1, with Ser and Leu residues in GmNPR1-1 and GmNPR1-2, respectively, suggested that there may be differences between the regulatory mechanisms of GmNPR1 and Arabidopsis NPR proteins. Therefore, SAR pathway in soybean is most likely regulated by GmNPR1 genes. ConclusionД¬omplementation analyses in Arabidopsis npr1-1 mutants revealed that homoeologous GmNPR1-1 and GmNPR1-2 genes are orthologous to Arabidopsis NPR1. Of the five cysteine residues, Cys 82, Cys 150, Cys 155, Cys 160, and Cys 216 involved in oligomer-monomer transition in NPR1, Cys 216 in GmNPR1-1 and GmNPR1-2 proteins was substituted to Ser and Leu, respectively. tomato ( Pst), and SAR was induced following Pst infection. In GmNPR1-1 and GmNPR1-2 transformed Arabidopsis npr1-1 mutant plants, SAR markers: (i) PR-1 was induced following INA treatment and (ii) BGL2 following infection with Pseudomonas syringae pv. GmNPR1-1 and GmNPR1-2 are the only soybean homologues of NPR1and are located in homoeologous regions.

They showed similar expression patterns among the organs, studied in this investigation. Soybean GmNPR1-1 and GmNPR1-2 genes showed high identities to Arabidopsis NPR1.

sojae-infected plants, SAR was induced against the bacterial pathogen, Pseudomonas syringae pv. Pathogenesis-related gene GmPR1 is induced following treatment of soybean plants with the SAR inducer, 2,6-dichloroisonicotinic acid (INA) or infection with the oomycete pathogen, Phytophthora sojae. We investigated if SAR in soybean is regulated by a pathway, similar to the one characterized in Arabidopsis. SAR in soybean was first reported following infection with Colletotrichum trancatum that causes anthracnose disease. Arabidopsis n on-expressor of PR1 ( NPR1) is a regulatory gene of the SA signal pathway. The development of SAR is associated with the induction of pathogenesis related ( PR) genes. Systemic acquired resistance (SAR) is induced in non-inoculated leaves following infection with certain pathogenic strains.
