“…The optimal (Fv/Fm) and effective ( F/Fm') quantum yield of photosystem II (PSII) was measured on fully expanded leaves using a PAM-2000 instrument (Walz, Effeltrich, Germany) according to [15]. The Fv/Fm was determined after 15 min dark adaptation, while F/Fm' was measured at steady state condition using 100 mol m -2 s -1 actinic light.…”

Wheat genotypes with different endogenous SA contents were investigated, in order to reveal how cadmium influences salicylic acid (SA) synthesis, and to find possible relationships between SA and certain protective compounds (members of the antioxidants and the heavy metal detoxification system) and between the SA content and the level of cadmium tolerance.Cadmium exposure induced SA synthesis, especially in the leaves, and it is suggested that the phenyl-propanoid synthesis pathway is responsible for the accumulation of SA observed after cadmium stress. Cadmium influenced the synthesis and activation of protective compounds to varying extents in wheat genotypes with different levels of tolerance; the roots and leaves also responded differently to cadmium stress. Although a direct relationship was not found between the initial SA levels and the degree of cadmium tolerance, the results suggest that the increase in the root SA level during cadmium stress in the Mv varieties could be related with the enhancement of the internal glutathione cycle, thus inducing the antioxidant and metal detoxification systems, which promote Cd stress tolerance in wheat seedlings. The positive correlation between certain SA-related compounds and protective compounds suggests that SA-related signalling may also play a role in the acclimation to heavy metal stress.

“…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. Recently, some researchers carried out on winter wheat (Tasgin et al 2006) and watermelon (Yang et al 2008) demonstrated that exogenous SA treatment could be involved in cold tolerance by regulating the activities of antioxidant enzymes.…”

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.

“…Freezing (subzero) or chilling (low positive) temperatures can cause injury or reduced growth depending on the cold tolerance of the species (Schneider et al, 1995;Pearce, 1999;Humphreys et al, 2003). Recent studies describe potentially valuable effects of salicylate treatment on cold tolerance in maize, rice, and wheat (Janda et al, 1999;Szalai et al, 2000;Kang and Saltveit, 2002;Tasgin et al, 2003), bean (Ding et al, 2002), cucumber (Kang and Saltveit, 2002), tomato (Senaratna et al, 2000;Ding et al, 2002), banana (Kang et al, 2003), and Persian lilac (Bernard et al, 2002).We have recently subjected a range of SA-related Arabidopsis genotypes to different temperatures (Clarke et al, 2004) and report here novel responses during prolonged growth at 5°C. Unlike most species in the above-mentioned cold tolerance papers, Arabidopsis is chilling resistant and able to grow to maturity at 5°C.…”

Salicylate Accumulation Inhibits Growth at Chilling Temperature in Arabidopsis

The growth of Arabidopsis plants in chilling conditions could be related to their levels of salicylic acid (SA). Plants with the SA hydroxylase NahG transgene grew at similar rates to Col-0 wild types at 23°C, and growth of both genotypes was slowed by transfer to 5°C. However, at 5°C, NahG plants displayed relative growth rates about one-third greater than Col-0, so that by 2 months NahG plants were typically 2.7-fold larger. This resulted primarily from greater cell expansion in NahG rosette leaves. Specific leaf areas and leaf area ratios remained similar in both genotypes. Net assimilation rates were similar in both genotypes at 23°C, but higher in NahG at 5°C. Chlorophyll fluorescence measurements revealed no PSII photodamage in chilled leaves of either genotype. Col-0 shoots at 5°C accumulated SA, particularly in glucosylated form. SA in NahG shoots showed similar tendencies at 5°C, but at greatly depleted levels. Catechol was not detected as a metabolite of the NahG transgene product. We also examined growth and SA levels in SA signaling and metabolism mutants at 5°C. The partially SAinsensitive npr1 mutant displayed growth intermediate between NahG and Col-0, while the SA-deficient eds5 mutant behaved like NahG. In contrast, the cpr1 mutant at 5°C accumulated very high levels of SA and its growth was much more inhibited than wild type. At both temperatures, cpr1 was the only SA-responsive genotype in which oxidative damage (measured as thiobarbituric acid-reactive substances) was significantly different from wild type.Salicylic acid (SA) has received much attention due to its association with economically important plant responses to disease and other stresses. Detailed evidence implicates SA in PR gene expression, systemic acquired resistance, and the hypersensitive response (Kunkel and Brooks, 2002). SA also seems to be involved in responses to abiotic stresses, such as ozone (Sharma et al., 1996;Rao and Davis, 1999;Koch et al., 2000), salt and osmotic stress (Borsani et al., 2001;Molina et al., 2002;Shim et al., 2003), UV-B (Surplus et al., 1998), drought (Senaratna et al., 2000Nemeth et al., 2002), paraquat (Kim et al., 2003, and heat (Dat et al., 1998a(Dat et al., , 1998b(Dat et al., , 2000Lopez-Delgado et al., 1998a;Senaratna et al., 2000;Larkindale and Knight, 2002; Clarke et al., 2004). Stress-influenced developmental transitions, including flowering (Hatayama and Takeno, 2003;Martinez et al., 2004), tuberization (Lopez-Delgado and Scott, 1997), and senescence (Morris et al., 2000), may also involve SA.Cold is one of the most important limitations to crop productivity and species distribution. Freezing (subzero) or chilling (low positive) temperatures can cause injury or reduced growth depending on the cold tolerance of the species (Schneider et al., 1995;Pearce, 1999;Humphreys et al., 2003). Recent studies describe potentially valuable effects of salicylate treatment on cold tolerance in maize, rice, and wheat (Janda et al., 1999;Szalai et al., 2000;Kang and Saltveit, 2002;Tasgin et al., 200...
