“…This SOS3/SOS2 complex phosphorylates and activates SOS1, hence the activated SOS1 has the ability to export excess ions and contribute to Na + ion homeostasis (Liu & Zhu, 1998;Liu et al, 2000;Quintero et al, 2002). SOS1 was discovered to be the downstream target of MPK6 by GST-pull-down assay (Smékalová et al, 2013). Moreover, during salt stress the phosphorylation degree of SOS1 increases (Davies et al, 2005).…”

“…ROS act as a dual role in plants. Superfluous ROS are detrimental to plant cells, yet moderate ROS components are necessarily playing important roles in signaling transduction and cell homeostasis (Smékalová et al, 2013). In fact, the up-regulation of the enzyme genes expression levels or the enhancement of the enzyme activities are the result of the cell signaling.…”

“…MAK3 and MAK6 can be activated by the elevated content of ROS (Lumbreras et al, 2010), and the activated MAK3 and MAK6 were relocated in the nucleus to strengthen or lessen gene expression triggering plant responses to ROS. Nevertheless, the MAPK phosphatase 2 (MKP2) which is induced by oxidative stress is able to dephosphorylate MPK3 and MPK6 to promote oxidative stress tolerance (Smékalová et al, 2013). Therefore, the signal regulatory pathways are intricate.…”

“…ABA is the foremost hormone and is induced by various stresses. It is able to regulate the adaption of the plants to stresses such as cold, drought, salinity, pathogen attacks, wounding and oxidative stress (Smékalová et al, 2013). It has been proven to be responsible for the changes in salt-stress-induced genes (De Bruxelles et al, 1996).…”

The increasing seriousness of salinization aggravates the food, population and environmental issues. Ameliorating the salt-resistance of plants especially the crops is the most effective measure to solve the worldwide problem. The salinity can cause damage to plants mainly from two aspects: hyperosmotic and hyperionic stresses leading to the restrain of growth and photosynthesis. To the adverse effects, the plants derive corresponding strategies including: ion regulation and compartmentalization, biosynthesis of compatible solutes, induction of antioxidant enzymes and plant hormones. With the development of molecular biology, our understanding of the molecular and physiology knowledge is becoming clearness. The complex signal transduction underlying the salt resistance is being illuminated brighter and clearer. The SOS pathway is the central of the cell signaling in salt stress. The accumulation of the compatible solutes and the activation of the antioxidant system are the effective measures for plants to enhance the salt resistance. How to make full use of our understanding to improve the output of crops is a huge challenge for us, yet the application of the genetic engineering makes this possible. In this review, we will discuss the influence of the salt stress and the response of the plants in detail expecting to provide a particular account for the plant resistance in molecular, physiological and transgenic fields.

“…It is therefore intriguing that MPK3 and MPK6 were identified as central regulators of plant innate immunity, hypoxia, and salt and osmotic stress responses, which control cross talk between different stresses, hormonal signals, and second messengers, such a ROS (Droillard et al, 2002;Teige et al, 2004;Chang et al, 2012;Rasmussen et al, 2012;Smekalova et al, 2013). MAP kinases were reported to phosphorylate other transcription factors such as WRKY33, which is involved in regulation of ethylene biosynthesis (Li et al, 2012), or MYB44, which regulates abscisic acid sensitivity (Nguyen et al, 2012b).…”

Heat shock factors (HSFs) are principal regulators of plant responses to several abiotic stresses. Here, we show that estradioldependent induction of HSFA4A confers enhanced tolerance to salt and oxidative agents, whereas inactivation of HSFA4A results in hypersensitivity to salt stress in Arabidopsis (Arabidopsis thaliana). Estradiol induction of HSFA4A in transgenic plants decreases, while the knockout hsfa4a mutation elevates hydrogen peroxide accumulation and lipid peroxidation. Overexpression of HSFA4A alters the transcription of a large set of genes regulated by oxidative stress. In yeast (Saccharomyces cerevisiae) two-hybrid and bimolecular fluorescence complementation assays, HSFA4A shows homomeric interaction, which is reduced by alanine replacement of three conserved cysteine residues. HSFA4A interacts with mitogen-activated protein kinases MPK3 and MPK6 in yeast and plant cells. MPK3 and MPK6 phosphorylate HSFA4A in vitro on three distinct sites, serine-309 being the major phosphorylation site. Activation of the MPK3 and MPK6 mitogen-activated protein kinase pathway led to the transcriptional activation of the HEAT SHOCK PROTEIN17.6A gene. In agreement that mutation of serine-309 to alanine strongly diminished phosphorylation of HSFA4A, it also strongly reduced the transcriptional activation of HEAT SHOCK PROTEIN17.6A. These data suggest that HSFA4A is a substrate of the MPK3/MPK6 signaling and that it regulates stress responses in Arabidopsis.
