“…Chlorothanolil a commercial fungicide which used widely to control various blight diseases and a constituent of this commercial fungicide 1,3-dichloro-2-fluorobenzene is identified in the GC-MS analysis of n-hexane fraction in present study. An aromatic carboxylic acid benzoic acid, 3-methyl-2-trimethylsilyloxytrimethysilyl ester identified in present study has antifungal potential against many fungal strains (Amborabe et al, 2002). Dicyclohexylethylphosphonate was also found in the GC-MS analysis of the C. album n-hexane fraction.…”

-Chenopodium album, leaves were selected to evaluate their antifungal potential against Ascochyta rabiei causative agent for chickpea blight. Different concentrations of methanolic extract of C. album leaves i.e. 1%, 2.5%, 4%, 5.5% and 7% were tested against the target fungus A. rabiei. Maximum reduction in the test fungal biomass (68%) was observed in 7% concentration. This methanolic leaf extract was partitioned and n-butanol, chloroform, n-hexane, ethyl acetate fractions were isolated according to their polarity. In vitro antifungal activity of these fractions was studied by serial dilution method. n-hexane fraction exhibited the highest antifungal potential with 55% inhibition in test fungal biomass, so this fraction was selected for Gas chromatography mass spectrometry (GC-MS) analysis. Total thirteen compounds identified in this analysis belonged to class aromatic hydrocarbons, hydrocarbons, saturated fatty acids, aromatic carboxylic acid, siloxanes, phosphonates and cardiac glycosides. These compounds might be responsible for antifungal activity of C. album.Keywords: antifungal potential, bathu, GC-MS, methanolic extract. RESUMO -Foram selecionadas folhas de Chenopodium album, para avaliação do potencial antifúngico contra o Ascochyta rabiei, agente causal da praga do grão de bico. Diferentes concentrações do extrato metanólico das folhas de C. album (1%, 2.5%, 4%, 5.5% e 7%) foram testadas contra o fungo-alvo

“…Para outros autores, o aS teve efeito de redução da perda de massa e da incidência de fungos, manutenção da firmeza, maior quantidade de vitamina C, maior at e teor de SSt, inibição da respiração e da produção de etileno (que são relacionados à aceleração do apodrecimento de frutos), e não causou efeitos negativos na aparência e no sabor de pêssegos, romãs e morangos, sendo a concentração de 2,0 mm de aS a mais efetiva na manutenção da qualidade destes frutos (amBoRaBe et al, 2002;SaYaRi et al, 2009;lolaei et al, 2012;SalaRi et al, 2012;Khademi ;eRShadi, 2013). Para Sayari et al (2009), que avaliaram o aS em morangos armazenados a 3º ±1 o C por 12 dias, considerou-se que a aplicação de aS pode ser boa alternativa na pós-colheita de morangos na manutenção dos parâmetros qualitativos e quantitativos, considerando-se sua alta perecibilidade; no entanto, considerou-se que existe comportamento distinto entre as cultivares.…”

INDUCTION OF RESISTANCE AND POST-HARVEST QUALITY OF BLACKBERRY TREATED WITH SALICYLIC ACIDABSTRACT -the objective of this study was to evaluate the effect of the elicitor salicylic acid (Sa) applied in post-harvest blackberry on conservation and the induction of resistance. Blackberry cultivar tupy fruits were harvested, selected and subjected to treatment with different concentrations of Sa (0.5, 1.0, 1.5 and 2.0 mm) and control (distilled water). We used a completely randomized design with four replications of 30 fruits per experimental unit. after 144 hours storage at the temperature of 8 °C, it was evaluated the weight loss, total soluble solids (tSS), titratable acidity (ta), ascorbic acid and the incidence of rottenness. at intervals of 24, 48, 96 and 144 hours fruit samples were withdrew for determination of total protein, anthocyanins, flavonoids and activity of the enzymes: phenylalanine ammonia-lyase (PAL), chitinase and β-1,3-glucanase. There was an increase of protein content and activation of β-1,3-glucanase with the application of SA, demonstrating induction of resistance in fruits by application of SA. The content of anthocyanins and flavonoids, as well as the activity of Pal, had changes during the experiment due to the application of Sa, which demonstrated activation of the phenylpropanoid route for synthesis of secondary metabolites. the treatments of aS did not affect the mass loss, ta, tSS, rot incidence, ascorbic acid and chitinase activity. Index terms: Rubus sp, phenylalanine ammonia lyase, chitinase and β-1,3-glucanase, anthocyanins and flavonoids.

“…In this respect, age-related resistance to pathogens in Arabidopsis is dependent on EDS1 signaling and associated more with the mobilization of SA to intercellular spaces between cells than with conventional SA-mediated NPR1-dependent intracellular changes in defense gene activation (67). At high concentrations, 2,3-DHBA was found to possess antifungal activity by disrupting cellular glutathione homeostasis in in vitro assays (68,69). At lower concentrations, 2,3-DHBA might protect the plant cell from oxidative stress because this is a function of 2,3-DHBA produced by bacterial pathogens infecting mammals.…”

An intricate network of hormone signals regulates plant development and responses to biotic and abiotic stress. Salicylic acid (SA), derived from the shikimate/isochorismate pathway, is a key hormone in resistance to biotrophic pathogens. Several SA derivatives and associated modifying enzymes have been identified and implicated in the storage and channeling of benzoic acid intermediates or as bioactive molecules. However, the range and modes of action of SA-related metabolites remain elusive. In Arabidopsis, Enhanced Disease Susceptibility 1 (EDS1) promotes SA-dependent and SAindependent responses in resistance against pathogens. Here, we used metabolite profiling of Arabidopsis wild type and eds1 mutant leaf extracts to identify molecules, other than SA, whose accumulation requires EDS1 signaling. Nuclear magnetic resonance and mass spectrometry of isolated and purified compounds revealed 2,3-dihydroxybenzoic acid (2,3-DHBA) as an isochorismate-derived secondary metabolite whose accumulation depends on EDS1 in resistance responses and during ageing of plants. 2,3-DHBA exists predominantly as a xylose-conjugated form (2-hydroxy-3-␤-O-D-xylopyranosyloxy benzoic acid) that is structurally distinct from known SA-glucose conjugates. Analysis of DHBA accumulation profiles in various Arabidopsis mutants suggests an enzymatic route to 2,3-DHBA synthesis that is under the control of EDS1. We propose that components of the EDS1 pathway direct the generation or stabilization of 2,3-DHBA, which as a potentially bioactive molecule is sequestered as a xylose conjugate.
