“…The phenolic compounds may involved in the enhancement of mechanical strength of the host cell walls by which it can restrict the entry of the pathogen (El Modafar et al 2012). The accumulation of phenolics by application of various elicitors has already been acknowledged (Dong et al 2010;El Modafar et al 2012;Gupta et al 2013). In this work, significantly enhanced accumulation of total phenols and flavonoids was observed in tomato leaves treated with CaCl 2 (0.5 %) or INA (2.5 mM), which might be an indication towards the enhancement of defense arsenals in tomato plants.…”

Improvement of the host resistance by using hazard free chemical elicitors is emerging as an alternative approach in the field of plant disease management. In our present work, we have screened the efficacy and possible mechanism of abiogenic elicitors like Dipotassium hydrogen orthophosphate (K 2 HPO 4 ), Oxalic acid (OA), Isonicotinic acid (INA), Salicylic acid (SA), Acetylsalicylate (AS), Arachidonic acid (AA) and Calcium chloride (CaCl 2 ) to stimulate innate immune responses in Lycopersicum esculentum Mill. Excised tomato leaves, treated with elicitors at three different concentrations, were found to stimulate defense and antioxidative enzymes, total phenol and flavonoid content after 24 h of incubation. CaCl 2 (0.5 %) followed by INA (2.5 mM) were found most effective in activation of all such defense molecules in tomato leaves. Furthermore, nitric oxide (NO), a key gaseous mediator in plant defense signaling, was also measured after subsequent elicitor application. Higher doses of elicitors showed an elevated level of reactive oxygen species (ROS) generation, enhanced lipid peroxidation rate and proline content, which indicates the extent of abiotic stress generation on the leaves. However, ROS production, lipid peroxidation rate and proline concentration remain significantly reduced as a result of CaCl 2 (0.5 %) and INA (2.5 mM) application. A sharp increase of total chlorophyll content was also recorded due to treatment of CaCl 2 (0.5 %). These results demonstrate the effects of different abiogenic elicitors to regulate the production of defense molecules. Results also suggest that among all such chemicals, CaCl 2 (0.5 %) and INA (2.5 mM) can be used as a potential elicitor in organic farming of tomato.

“…These include, e.g. caffeic acid and salvianolic acid from Salia miltiorrhiza (Dong et al 2010), phenolic acids (cichoric acid and chlorogenic acid) from Rauvolfia serpentine (Nair et al 2013), p-coumaroylmalic acid from Thunbergia alata (Housti et al 2002). Due to their stress-related accumulation phenols are considered as stress metabolites.…”

Salicylic acid regulates secondary metabolites content in leaves of Matricaria chamomilla

2013

The influence of increasing doses of salicylic acid (SA) on selected physiological parameters and the content of coumarin-related compounds of diploid and tetraploid cultivars of Matricaria chamomilla plants were studied. Forty-eight hours after treatment SA showed growth-promoting effect with decrease in tissue water content, chlorophylls and soluble proteins. High doses of SA led to an increase of reactive oxygen species (hydrogen peroxide and superoxide radical) resulted in membrane damage (measured by accumulation of malondialdehyde). Changes in secondary metabolites accumulation in leaves were also observed. The pattern of quantitative changes of studied compounds was similar in tetraploid and diploid plants. The content of herniarin and its precursor (Z )-and (E )-2-β-D-glucopyranosyloxy-4-methoxycinnamic acid increased simultaneously. A considerable increase of umbelliferone and decrease in chlorogenic acid was registered. The rise of ene-yne-dicycloether in treated plant was also detected.

“…Both phenolic acid accumulations were significantly increased at 8 and 96 h after the applications of 3.125-25 mg/L of SA, but were significantly less with 32-50 mg/L of SA. After the 96 h treatments with 3.125-25 mg/L of SA, the concentration of the phenolic acids decreased significantly compared to the amount 8 h after the treatments, but were still higher than that of the control [61]. SA with transgenic technology, highly enhanced the production of tanshinones in S. miltiorrhiza hairy roots [62].…”
