Low temperature is one of the most important limiting factors for plant growth throughout the world. Exposure to low temperature may cause various phenotypic and physiological symptoms, and may result in oxidative stress, leading to loss of membrane integrity and to the impairment of photosynthesis and general metabolic processes. Salicylic acid (SA), a phenolic compound produced by a wide range of plant species, may participate in many physiological and metabolic reactions in plants. It has been shown that exogenous SA may provide protection against low temperature injury in various plant species, while various stress factors may also modify the synthesis and metabolism of SA. In the present review, recent results on the effects of SA and related compounds in processes leading to acclimation to low temperatures will be discussed.

Growth Promoting

The effects of plant inoculation with plant growth-promoting rhizobacteria (PGPR) and those resulting from the exogenous application of salicylic acid (SA) or methyl jasmonte (MeJA) on total phenolic content (TPC) and monoterpenes in Mentha x piperita plants were investigated. Although the PGPR inoculation response has been studied for many plant species, the combination of PGPR and exogenous phytohormones has not been investigated in aromatic plant species. The exogenous application of SA produced an increase in TPC that, in general, was of a similar level when applied alone as when combined with PGPR. This increase in TPC was correlated with an increase in the activity of the enzyme phenylalanine ammonia lyase (PAL). Also, the application of MeJA at different concentrations in combination with inoculation with PGPR produced an increase in TPC, which was more relevant at 4 mM, with a synergism effect being observed. With respect to the main monoterpene concentrations present in peppermint essential oil (EO), it was observed that SA or MeJA application produced a significant increase similar to that of the combination with rhizobacteria. However, when plants were exposed to 2 mM MeJA and inoculated, an important increase was produced in the concentration on menthol, pulegone, linalool, limonene, and menthone concentrations. Rhizobacteria inoculation, the treatment with SA and MeJA, and the combination of both were found to affect the amount of the main monoterpenes present in the EO of M. piperita. For this reason, the expressions of genes related to the biosynthesis of monoterpene were evaluated, with this expression being positively affected by MeJA application and PGPR inoculation, but was not modified by SA application. Our results demonstrate that MeJA or SA application combined with inoculation with PGPR constitutes an advantageous management practice for improving the production of secondary metabolites from M. piperita.

Antioxidant Capacities

Lilium pumilum DC has been used as an important medicinal and edible plant species in China. To provide sufficient experimental evidence for further utilization of wild L. pumilum, 12 organs were evaluated for phenolic compounds and antioxidant capacities. The results showed that (-)-epicatechin was the most abundant phenolic compound, and salicylic acid as the most abundant phenolic acid. The leaf, flower bud, petal and upper stem had higher phenolic compound contents and stronger antioxidant capacities.

Resistant Lines

Plant responses to biotic and abiotic stresses are usually accompanied by the release of reactive oxygen species including hydrogen peroxide. Hydrogen peroxide plays a direct role in defense and is involved in many signal transduction pathways that lead to the proliferation of other defenses. Because catalase helps to maintain reactive oxygen homeostasis during biotic and abiotic stress, its activity was measured in various cob tissues during maize ear development. Catalase activity was determined in immature and mature embryos, pericarp, and rachis tissues of maize lines that are resistant and susceptible to Aspergillus flavus infection. The effect of fungal inoculation on catalase activity was also measured. Over two years of field experimentation, a correlation was observed between resistance and the level of catalase-specific activity in immature embryos, which was significantly higher in resistant lines (P < 0.0001). Furthermore, catalase activity in the resistant lines was significantly higher in immature embryos from inoculated ears (P = 0.0199). No correlation was observed between resistance and catalase activity in other ear tissues. Levels of hydrogen peroxide, the catalase substrate, and salicylic acid in the embryo were also determined. The resistant lines showed lower levels of H2O2 (P < 0.0001) and higher levels of salicylic acid (P < 0.0001) as compared with the susceptible lines. Catalase 3 was sequenced from the aflatoxin-resistant (Mp313E) and -susceptible (SC212m) inbreds. The predicted amino acid sequence indicated that there was a 20-aa deletion in the resistant inbred that might affect enzymatic activity. Unlike many plant-pathogen interactions, it appears that lowering H2O2 levels helps to prevent A. flavus infection and subsequent aflatoxin accumulation.

In this work, some physiological parameters of micropropagated Bac Kan local alpinia (Alpinia coriandriodora D. Fang) affected by drought and salicylic acid treatments under drought condition were analyzed. In comparison to well watered plants, the droughted plants have lower contents of relative water, photosynthetic pigments, anthocyanins in leaves and Fv/Fm ratio. In constrat, proline content and activity of both catalase and peroxidase are higher in droughted plants. SA treatments, 10 M in particular, attenuate damages in droughted alpinia plants by affecting on some physiological parameters. An increase in content of relative water, photosynthetic pigments (chlorophylls and carotenoids), and anthocyanins were observed in leaves of treated plants in comparison to non-treated plants under drought condition. Fv/Fm ratio and peroxidase activity are higher in 10 M SA-treated plants than non-treated ones. Both 10 M and 100 M SA treatments lead to a decrease in proline accumulation and catalase activity in leaves of droughted plants.

The Cross

Transgenic tobacco plants with severely reduced catalase activity were crossed with NahG plants that do not accumulate salicylic acid. Some of the progeny from the cross spontaneously developed necrosis when grown under strong light, similar to that observed on the parental severely catalase-deficient plants. However, in contrast to the parental catalase-deficient plants, these progeny plants did not constitutively express PR-1 genes or develop enhanced resistance. Thus, salicylic acid appears to be required for the induction of these defense responses in catalase-deficient tobacco plants.
