“…In addition, several studies have evaluated the roles of exogenous SA in modulating plant response to several abiotic and biotic stresses such as ultraviolet light (Mahdavian et al 2008), drought (Kadioglu et al 2011;Saruhan et al 2012), salt (Mutlu et al 2009a;Mutlu and Atici 2013;Khan et al 2014;Jayakannan et al 2015), heat (Khan et al 2013), heavy metals (Guo et al 2009;Popova et al 2009) and plant pathogenesis (Wang et al 2007). For example, exogenous SA treatment could improve chilling tolerance in maize (Janda et al 1999;Horvath et al 2002), tomato (Ding et al 2002), banana (Kang et al 2003), winter wheat (Tasgin et al 2006;Esim and Atici 2015), guayule (Sundar et al 2004), red globe grape (Li et al 2005), Brassica juncea (Setia et al 2006), radish (Biao, 2006), cucumber (Xia et al 2007;Lei et al 2010), grass (Wang et al 2009a) and barley (Mutlu et al 2013a(Mutlu et al , 2013b.…”

In this work, the time-dependent effect of exogenous salicylic acid (SA) applied before cold stress was investigated on the regulation of antioxidative respond mechanisms in two barley (Hordeum vulgare L.) cultivars (Akhisar and Tokak) differed in cold tolerance. SA (0.1 mM) was applied to 7-days old barley seedlings growing under control conditions (20/18°C). After this application, the seedlings were transferred to cold conditions (7/5°C) at different times (7, 14, 21 and 28 days) for 3 days. Then, the contents of malondialdehyde (MDA), hydrogen peroxide (H 2 O 2 ) and the activities of antioxidant enzymes such as superoxide dismutase (SOD), catalase (CAT) and peroxidase (POX) were determined in the leaves (control, cold and SA + cold) from the seedlings harvested at 10, 17, 24 and 31 days. Moreover, the effect of cold stress was evaluated on the endogenous SA level at the both cultivars by comparing to control plants. The MDA content increased in the cold treatment while it decreased in the SA treatment at all the days studied at the both cultivars. The SA + cold treatment could have a variable effect on H 2 O 2 content at the tolerant barley (Tokak) while decreased its content at the sensitive cultivar (Akhisar). The SA + cold treatment could increase the activities of POX and SOD at both cultivars, but it increased the CAT activity at the tolerant cultivar while decreased at the sensitive cultivar. In addition, the content of endogenous SA was decreased by cold stress at all the days studied at the barley cultivars as compared to control plants. The results show that the SA treatment could be effective on the regulation of the parameters studied at cold conditions until 31 days after SA application, and the importance of exogenous SA treatment before cold stress. It was concluded that exogenous and endogenous SA could play an ameliorating role on cold tolerance by regulating reactive oxygen species and the activities of antioxidative enzymes in both cold-sensitive and cold-tolerant cultivars of barley.

“…Segundo (Jayakannan et al, 2015), o ácido salicílico controla a absorção de Na + nas raízes e seu transporte para a parte aérea, evita o vazamento de K + induzido pelo estresse salino das raízes via canal de retificação de potássio ativado por despolarização, aumento assim a concentração de K + na parte aérea das plantas.…”

“…Salicylic acid (SA) is the induced in plants due to pathogen intereaction but is not present in all plants as a defense mechanism (Jayakannan et al 2015). SA is well known to promote some secondary metabolites accumulation as an abiotic elicitor For example SA induced pilocarpine accumulation in Jaborandi folium (Avancini et al 2003)and inapic acid, rutin and naringin were detected only in SA treatments to peppermint and antioxidant capacity was also improved (Pérez et al 2014).…”

A wide range of external stress stimuli trigger plant cells to undergo complex network of reactions that ultimately lead to the synthesis and accumulation of secondary metabolites. Accumulation of such metabolites often occurs in plants subjected to stresses including various elicitors or signal molecules. Throughout evolution, endophytic fungi, an important constituent in the environment of medicinal plants have known to form long-term stable and mutually beneficial symbiosis with medicinal plants. The endophytic fungal elicitor can rapidly and specifically induce the expression of specific genes in medicinal plants which can result in the activation of a series of specific secondary metabolic pathways resulting in the significant accumulation of active ingredients. Here we summarize the progress made on the mechanisms of fungal elicitor including elicitor signal recognition, signal transduction, gene expression and activation of the key enzymes and its application to this process. This paper provides guidance on studies which may be conducted to promote the efficient synthesis and accumulation of active ingredients by the endogenous fungal elicitor in medicinal plant cells, and provides new ideas and methods of studying the regulation of secondary metabolism in medicinal plants.
