“…The data suggested that SA was taken up by the seed and it was converted to bound forms. These results are in accordance with our earlier findings where it was shown that soaking of pea seed in radioactively labelled SA solution led an increased level of labelled bound SA in the seed, while in the epicotyl the increased level of SA was mainly due to de novo synthesis of SA (Szalai et al 2011).…”

The application of naturally occurring biologically active compounds could be an effective method to improve crop productivity under changing environmental conditions. In the present work the effects of priming maize seed with salicylic acid were tested on the grain yield under field conditions, and on the salicylic acid and polyamine metabolism under controlled environmental conditions. The field data suggested that the beneficial effects of pretreating maize seed with salicylic acid were mainly detectable in the yield in the case of early sowing dates. When young maize seedlings were exposed to low temperature stress, priming the seed with salicylic acid only modified the salicylic acid levels in the seed but not in the roots or leaves. The data suggested that salicylic acid was taken up by the seed and was then converted to bound forms. In contrast to salicylic acid, 5 days after sowing there was a substantial increase in the free form of ortho-hydroxy cinnamic acid in the seed, roots and leaves. Priming with salicylic acid also led to an increase in the putrescine content and a slight decrease in spermidine in the seed. The levels of putrescine, spermidine and spermine also increased in the roots of plants treated with salicylic acid under normal growth conditions. The results suggest that polyamines may also contribute to the stress tolerance of plants primed with salicylic acid.

“…Furthermore, exogenous SA may also enhance the plant's own de novo SA synthesis, as it was illustrated by the changes in free and bound SA levels in pea plants growing from seeds pre-treated with SA before sowing (Szalai et al 2011). Pre-soaking the seeds in SA also increased the activities of some antioxidant enzymes, namely ascorbate peroxidase and guaiacol peroxidase and the level of oHCA, which may also affect the tolerance to environmental stressors (Fig.…”

“…The role of shikimate pathway in SA synthesis of young pea plants was also demonstrated (Szalai et al 2011). This shikimic acid pathway is also a link between metabolism of carbohydrates and biosynthesis of aromatic compounds like phenylalanine, tyrosine and tryptophan (Herrman and Weaver 1999).…”

Salicylic acid and photosynthesis: signalling and effects

et al. 2014

Salicylic acid (SA) is a well-known signalling molecule playing a role in local and systemic acquired resistance against pathogens as well as in acclimation to certain abiotic stressors. As a stress-related signalling compound, it may directly or indirectly affect various physiological processes, including photosynthesis. The effects of exogenously applied SA on plant 2 physiological processes under optimal environmental conditions are controversial. Several studies suggest that SA may have a positive effect on germination or plant growth in various plant species. However, SA may also act as a stress factor, having a negative influence on various physiological processes. Its mode of action depends greatly on several factors, such as the plant species, the environmental conditions (light, temperature, etc.) and the concentration. Exogenous SA may also alleviate the damaging effects of various stress factors, and this protection may also be manifested as higher photosynthetic capacity.Unfavourable environmental conditions have also been shown to increase the endogenous SA level in plants. Recent results strongly suggest that controlled SA levels are important in plants for optimal photosynthetic performance and for acclimation to changing environmental stimuli. The present review discusses the effects of exogenous and endogenous SA on the photosynthetic processes under optimal and stress conditions. Running title: Salicylic acid and photosynthesis

“…It has been proved in many cases that adding special plant growth regulators to priming solution may improve performance of seed priming in terms of better germination and early growth under abiotic stresses (Alonso-Ramirez et al, 2009;Liu et al, 2011). Salicylic acid (SA) as a signal molecule contributes in induction of stress tolerance within plant cells (Horvath et al, 2007) and several studies proposed that SA play an important role in induction of defense mechanisms against abiotic stresses within plant cells (Szalai et al, 2011;Alonso-Ramırez et al, 2009;Shah, 2003).…”

Due to low rainfall at early autumn, smooth vetch seedling growth in rain-fed lands often is limited by water deficit stress yet the data regarding the reactions of smooth vetch to water deficit at early growth stages are pretty rare. The objective of current study was to examine possibility of using priming treatments (hydro priming and priming salicylic acid) to alleviate the inhibitory effect of water deficiency during early growth of Smooth Vetch. In this respect, seeds were soaked in distilled water (hydro priming) or 0.5 mM solution of SA for 36 h at 10 °C then dried back to original moisture content. Pots were irrigated for 25 days at four levels of available water containing field capacity (FC), 75% FC, 50% FC and 25% FC. In general, seedling emergence and early growth were markedly limited by increasing water deficiency. However, priming treatments particularly with SA caused considerable improvement in either emergence or growth of seedlings (dry weight, length). The obtained results showed that primed samples exhibited higher accumulation of proline, glycine betaine (GB) under all levels of available water except 100% FC and also higher total soluble sugars (TSS) and trehalose under severe water deficit (25% FC). SA primed samples had higher relative water content especially under higher levels of water deficiency. The more balanced water status within SA primed samples also was accompanied with higher accumulation of proline and glycine betaine. There were significant differences between two priming treatments in terms of proline and GB content within seedlings and SA priming considerably increased proline and GB accumulation. In contrast to proline and GB, TSS and trehalose content wasn't influenced by SA treatment and both hydro and SA primed samples showed statistically similar quantities.
