“…In the nearest, the ribosomal RNA methylation was discovered to respond to abiotic stress (Baldridge & Contreras, 2013). In addition, the mitogen-activated protein kinase (MAPK) signaling pathways, which are involved in stress responses, are the highly conserved and important regulating system in plants (Colcombet & Hirt, 2008;Sinha et al, 2011).…”

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.

“…5 The MAPK signaling cascade is a 3-tier phospho-relay signaling module that is evolutionarily conserved in all eukaryotes. 6,7 In plants, the MAPK signal transduction network is implicated in various biotic and abiotic stress responses, Recently, MAPK was also shown to act as a nodal point of crosstalk between SUB1A1 and submergence signaling pathways.Thus, the present study was undertaken to investigate the role of MAPK cascade components in a mega-variety lacking SUB1A1 gene. It was intriguing to investigate the possible activation of MAPK cascade in absence of the potential downstream executor i.e.…”

Mitogen-activated protein kinase (MAPK) signaling cascade has been extensively studied in plants. Recently, this important network has been implicated in imparting submergence tolerance by facilitating the phosphorylation of the SUB1A1 protein. In this study, we try to examine the speculative role of MAPK cascade components in another rice mega-variety Pusa Basmati 1. The study reports that potential MAPK cascade components are triggered by submergence stress. Overall, the results provide a brief understanding of activation of MAPK cascade components post submergence stress in a rice variety, which does not harbor the SUB1A1, and in turn, succumbs to prolonged submergence stress. KEYWORDSMAPK; submergence; Pusa Basmati1; rice Pusa Basmati 1 is a characteristic aromatic, long-slender grained rice cultivar grown in the foothills of Himalayas in the Indian sub-continent. According to the 2014-2015 survey conducted by the Ministry of Commerce and Industry, Government of India, India is the leading exporter of the 'Basmati Rice' to the global market. The agro-climatic changes by global warming are major concern for the yield of this economically important rice cultivar. Incidence of flash flooding has emerged as a major challenge to farmers cultivating this aromatic rice grain. These rice cultivars are adapted to thrive in standing water but at the same time are prone to flash flooding and complete submergence. In rice, in general, various submergence directed physiological and molecular studies have identified, 2 submergence survival schemes firstly, the low-oxygen quiescence strategy (LOQS), which is typical of lowland rice varieties and on a whole, is characterized by a general constraint of growth due to cellular metabolism deficit. This characteristic strategy is displayed by plant species that recurrently endure deep floods. The second strategy is designated as the low-oxygen escape strategy (LOES), which is typical to upland rice cultivars and is categorized by rapid elongation of below water plant tissues especially, stems or leaves. This rapid growth enables the photosynthesizing tissues to outgrow shallow floodwaters and reach the air. LOES is predominantly governed by SNORKEL1/2 (SK1 and SK2), which are tandem ethyleneresponsive factor (ERF) genes. 1 On the contrary, LOQS involves stress-induced repression of carbohydrate resource consumption, in conjunction with plant growth inhibition. This quiescent strategy is majorly governed by the SUB1A gene of the SUBMERGENCE1 (SUB1) QTL. 2 The identification of the SUB1 QTL was a major landmark for plant breeders, which enabled the transfer of this quintessential locus by marker-assisted backcrossing strategy into the farmer-preferred mega-varieties. 3 Pusa Basmati 1 mega-variety is intolerant to complete inundation. Submergence leads to detrimental effects particularly during the vegetative stage. Flooding substantially decreases the number of panicles, the number of grains per panicle and grainfilling proportion. This also leads to delayed flowering and ...

“…6,7 The completion of sequencing project revealed the presence of 15 MAPKs, 8 MAP2Ks, and 75 MAP3Ks in rice genome. 5,8 Out of eight MAP2Ks reported from rice, a partial functional characterization of only OsMKK6 has been performed so far. OsMKK6 (earlier named as OsMEK1) specifically and physically interacted with OsMPK3 (earlier named as OsMAP1) in moderate low temperature stress signaling as shown by yeast two hybrid assay.…”
