“…As we know, photosynthates and other plant compounds are transported from aboveground parts of plants to their underground parts mainly by means of phloem vessels [ 46 ]. Therefore, the systematic effects of exogenous salicylic acid on the chemical defense responses of non-treated plant parts have also attracted the attention of some scholars [ 18 , 19 , 47 ]. For example, Methenni et al [ 19 ] reported that the foliar application of 1.0 mM SA systematically increased the root contents of total phenolics and flavonoids in the Oueslati olive variety after 15 d. However, we reported for the first time that the concentrations of salicylic acid and post-treatment time had different effects on the same detection index of the same parts of maize seedlings.…”

Salicylic acid (SA) plays a critical role in allergic reactions of plants to pathogens and acquired systemic resistance. Thus far, although some research has been conducted on the direct effects of different concentrations of SA on the chemical defense response of treated plant parts (leaves) after at multiple post-treatments times, few research has reported on the systematic effects of non-treated parts (roots). Therefore, we examined direct and systemic effects of SA concentration and time following foliar application on chemical defense responses in maize variety 5422 with two fully expanded leaves. In the experiments, maize leaves were treated with different SA concentrations of 0.1, 0.5, 1.0, 2.5, 5.0 mM, and then, the presence of defense chemicals and enzymes in treated leaves and non-treated roots was measured at different time points of 3, 12, 24, 48, 72 h following SA foliar application. The results showed that direct and systemic effects of SA treatment to the leaf on chemical defense responses were related to SA concentration and time of measurement after spraying SA. In treated leaves, total phenolics content increased directly by 28.65% at the time point of 12 h following foliar application of 0.5 mM SA. DIMBOA (2,4-dihydroxy-7-methoxy-2H, 1, 4-benzoxazin-3 (4H)-one) content was directly enhanced by 80.56~551.05% after 3~72 h following 0.5~5.0 mM SA treatments. Polyphenol oxidase and superoxide dismutase activities were directly enhanced after 12~72 h following 0.5~5.0 mM SA treatments, whereas peroxidase and catalase activities were increased after 3~24 h following application of 1.0~5.0 mM SA. In non-treated roots, DIMBOA content and polyphenol oxidase activity were enhanced systematically after 3~48 h following 1.0~5.0 mM SA foliar treatments. Superoxide dismutase activities were enhanced after 3~24 h following 0.5~2.5 mM SA applications, but total phenolics content, peroxidase and catalase activity decreased in some particular concentrations or at the different times of measurement in the SA treatment. It can be concluded that SA foliar application at 1.0 and 2.5 mM produces strong chemical defense responses in maize, with the optimal induction time being 24 h following the foliar application.

Salicylic acid (SA) is well known hormonal molecule involved in cell death regulation. In response to a broad range of environmental factors (e.g., high light, UV, pathogens attack), plants accumulate SA, which participates in cell death induction and spread in some foliar cells. LESION SIMULATING DISEASE 1 (LSD1) is one of the best-known cell death regulators in Arabidopsis thaliana. The lsd1 mutant, lacking functional LSD1 protein, accumulates SA and is conditionally susceptible to many biotic and abiotic stresses. In order to get more insight into the role of LSD1-dependent regulation of SA accumulation during cell death, we crossed the lsd1 with the sid2 mutant, caring mutation in ISOCHORISMATE SYNTHASE 1(ICS1) gene and having deregulated SA synthesis, and with plants expressing the bacterial nahG gene and thus decomposing SA to catechol. In response to UV A+B irradiation, the lsd1 mutant exhibited clear cell death phenotype, which was reversed in lsd1/sid2 and lsd1/NahG plants. The expression of PR-genes and the H2O2 content in UV-treated lsd1 were significantly higher when compared with the wild type. In contrast, lsd1/sid2 and lsd1/NahG plants demonstrated comparability with the wild-type level of PR-genes expression and H2O2. Our results demonstrate that SA accumulation is crucial for triggering cell death in lsd1, while the reduction of excessive SA accumulation may lead to a greater tolerance toward abiotic stress.

“…Studies have shown that soil amendment with vermicompost enhances the performance of PGPR resulting in increased seed yield (Bajracharya and Rai, 2009;Singh et al, 2012) and protection against pathogen in chickpea (Sahni et al, 2008). However, most studies indicate individual effect of vermicompost, PGPR and salicylic acid on plant growth and development and induction of defense responses in chickpea (Sahni et al, 2008;War et al, 2011;Bhar et al, 2018;Mazumdar et al, 2019). In the present investigation, an attempt was made to determine the effect of vermicompost and PGPR isolate for improved plant growth.…”

Aim: The aim of the present study was to evaluate the ability of integration of salicylic acid, vermicompost and bioagent for effective management of chickpea wilt disease. Methodology: The effectiveness of salicylic acid and ZnSO4 unaided and in combination with Plant growth-promoting rhizobacteria (PGPR) and vermicompost were evaluated against Fusarium wilt of chickpea under natural condition. Three sets of experiment with nine treatments were conducted in earthen pots in completely randomized design. Ten seeds of wilt susceptible chickpea variety JG 62 were sown. Twenty-days-old plants were sprayed with salicylic acid (Set I), ZnSO4 (Set II) and distilled H2O (Set III). After 24 hr of foliar spray, the whole set of treatment was inoculated with Fusarium oxysporum f. sp. ciceri inoculums, except uninoculated control. The number of wilted seedlings in each pot for each treatment were recorded at 10, 20 and 30 days post-inoculation (dpi) and compared with uninoculated pots. Results: The combined effect of vermicompost amendment @15% and pre-inoculation treatment of salicylic acid showed 0.00, 6.67 and 6.67% wilt incidence whereas treatments having ZnSO4 as pre-inoculation foliar spray resulted in 0.00, 13.33 and 13.33% wilt incidence at 10, 20 and 30 dpi, respectively. Further, the combined treatment of 15% vermicompost along with seed bacterization and pre-inoculation foliar spray of salicylic acid showed complete protection against F. oxysporum f. sp. ciceri. The beneficial effect of vermicompost and PGPR isolate on root and shoot length, and fresh and dry weight of chickpea plants were also observed. Interpretation: High potential for integrating vermicompost, bioagent and foliar application of salicylic acid to surrogate chemical fungicides for eco-friendly and sustainable management of wilt disease in chickpea.
