“…In addition, some synthetic compounds elicit SAR-related events, such as the induction of broad disease resistance and the expression of SAR marker genes, but have very little or no antibiotic activity. Among these chemicals, 2,6-dichloroisonicotinic acid (Mé traux et al, 1990;Uknes et al, 1992), benzo(1,2,3)thiadiazole-7-carbothioic acid S-methyl ester (BTH) Gö rlach et al, 1996;Lawton et al, 1996), N-cyanomethyl-2-chloroisonicotinamide (Yoshida et al, 1990;Nakashita et al, 2002a;Yasuda et al, 2003a), 3-chloro-1-methyl-1H-pyrazole-5-carboxylic acid (Nishioka et al, 2003;Yasuda et al, 2003b), andN-(3-chloro-4-methylphenyl)-4-methyl-1,2,3-thiadiazole-5-carboxamide (Yasuda et al, 2004) induce SAR by acting at the point of SA accumulation or downstream in the SAR signal transduction pathway. By contrast, probenazole and its derivative, 1,2-benzisothiazol-3(2H)-one1,1-dioxide (BIT), induce SAR by stimulating the SAR signaling pathway upstream of SA (Watanabe et al, 1979;Yoshioka et al, 2001;Nakashita et al, 2002b).…”

Systemic acquired resistance (SAR) is a potent innate immunity system in plants that is effective against a broad range of pathogens. SAR development in dicotyledonous plants, such as tobacco (Nicotiana tabacum) and Arabidopsis thaliana, is mediated by salicylic acid (SA). Here, using two types of SAR-inducing chemicals, 1,2-benzisothiazol-3(2H)-one1,1-dioxide and benzo(1,2,3)thiadiazole-7-carbothioic acid S-methyl ester, which act upstream and downstream of SA in the SAR signaling pathway, respectively, we show that treatment with abscisic acid (ABA) suppresses the induction of SAR in Arabidopsis. In an analysis using several mutants in combination with these chemicals, treatment with ABA suppressed SAR induction by inhibiting the pathway both upstream and downstream of SA, independently of the jasmonic acid/ethylene-mediated signaling pathway. Suppression of SAR induction by the NaCl-activated environmental stress response proved to be ABA dependent. Conversely, the activation of SAR suppressed the expression of ABA biosynthesis–related and ABA-responsive genes, in which the NPR1 protein or signaling downstream of NPR1 appears to contribute. Therefore, our data have revealed that antagonistic crosstalk occurs at multiple steps between the SA-mediated signaling of SAR induction and the ABA-mediated signaling of environmental stress responses.

“…Thus, in addition to the anti-rice blast effect reported previously, 1) CMPA provided resistance against a disease caused by a bacterial pathogen, without showing direct antibacterial activity. These findings suggest that CMPA acts on the rice plants to induce resistance against diseases.…”

“…1) However, CMPA did not have any significant effects on the hyphal growth, spore germination, and appressorium formation of Pyricularia oryzae. 1) These results suggest that the anti-rice blast activity of CMPA was caused by its effect on the rice plants and not on P. oryzae. On the other hand, CMPA induced the expression of pathogenesis related (PR) genes and a broad range of disease resistance without exhibiting antibacterial activity in tobacco, indicating that CMPA acts as an inducer of systemic acquired resistance (SAR) in tobacco 2) like probenazole (PBZ; 3-allyloxy- [3][4][5] acibenzolar-S-methyl (BTH; benzo [1,2,3]thiadiazole-7-carbothionic acid S-methyl ester), 6,7) N-cyanomethyl-2-chloroisonicotinamide (NCI), [8][9][10] and tiadinil (TDL).…”

A pyrazole derivative, 3-chloro-1-methyl-1H-pyrazole-5-carboxylic acid (CMPA), exhibited high anti-rice blast activity without any significant antimicrobial activity. To assess the mode of action of CMPA, its effects on rice bacterial leaf blight caused by Xanthomonas oryzae pv. oryzae and the expression of a defenserelated gene were examined. The treatment of CMPA reduced the disease symptoms in a dose-dependent manner, but CMPA did not exhibit any direct antibacterial activity against X. oryzae at concentrations up to 1 mg/ml. The treatment of CMPA induced the expression of PBZ1, a defense-related gene, which is evoked by several plant activators. This ability to induce PBZ1 expression and enhance disease resistance without antimicrobial activity suggests that CMPA can activate systemic acquired resistance in rice as well as in tobacco.
