“…(For interpretation of the references to color in this figure legend, the reader is referred to the web version of this article.) a tomato ABA-regulated transcription factor involved in stressinduced responses was shown to be involved in the regulation of primary carbohydrate and amino acid metabolism (Bastias et al, 2014). Additionally, sugar accumulation is a function of ABA dependent invertase and transporters biosynthesis (Medici et al, 2014).…”

“…BZI-1 TFs bind specifically to the ACEs (ACGT core elements; example: G-box, GT-box , etc. ), thereby controlling stress-specific regulation of primary (NIN88, Adh, α-amylase, AtEM6, ProDH, Dc3, LEA, Kin1, BAD, GST and SbeI; Lu et al, 1996; Finkelstein and Lynch, 2000; Kim et al, 2002; Satoh et al, 2004; Wobbes, 2004; Iven et al, 2010; Bastías et al, 2011, 2014) and specialized metabolism genes (CHI, CHS, Ah24, DFR and PAL; Strathmann et al, 2001; Heinekamp et al, 2002, 2004; Fujita et al, 2005; Iven et al, 2010; Yoshida et al, 2015). It can therefore be inferred that the ACEs and bZIP TFs interactions can play a central role in coregulating primary and specialized metabolism in plants.…”

“…The bZIP family (basic leucine zipper) is one of the largest TF families in plants, which is involved in diverse regulatory functions, like abiotic and biotic stress tolerance, hormone signaled gene regulation, sugar signaling, nitrogen, carbon and energy metabolism, light responsiveness and developmental regulation (like cell elongation, differentiation, flowering, senescence and maturation of seedlings, Chuang et al, 1999; Wei et al, 2012; Bastías et al, 2014; Llorca et al, 2014; Zhao et al, 2016). The bZIP TFs have a widespread presence among eukaryotes (17 in S. cerevisiae , 27 in Drosophila, 75 in A. thaliana , 89 in rice, 125 in maize, 131 in soybean, 69 in tomato and 585 among six leguminous plants: G. max, M. truncatula, P. vulgaris, C. arietinum, C. cajan , and L. japonicus , Fassler et al, 2002; Wei et al, 2012; Llorca et al, 2014; Li D. et al, 2015; Wang et al, 2015).…”

“…For example, studies have indicated that the expression of primary ( SUSY, LEAs, CWIN, vINV, PP2C ) and specialized metabolism genes ( PAL, CHS, DFR, FLS ) is regulated by AREB- ABRE interactions via ABA signaling (Narusaka et al, 2003; Gómes-Porras et al, 2007; Bastías et al, 2011, 2014; Basu et al, 2014; Yoshida et al, 2015). Similarly, Opaque 2 (O2) is an endosperm-specific TF that was found to enhance the expression of several primary and specialized metabolism genes (Table 2).…”

Stress-Mediated cis-Element Transcription Factor Interactions Interconnecting Primary and Specialized Metabolism in planta

2016

Plant specialized metabolites are being used worldwide as therapeutic agents against several diseases. Since the precursors for specialized metabolites come through primary metabolism, extensive investigations have been carried out to understand the detailed connection between primary and specialized metabolism at various levels. Stress regulates the expression of primary and specialized metabolism genes at the transcriptional level via transcription factors binding to specific cis-elements. The presence of varied cis-element signatures upstream to different stress-responsive genes and their transcription factor binding patterns provide a prospective molecular link among diverse metabolic pathways. The pattern of occurrence of these cis-elements (overrepresentation/common) decipher the mechanism of stress-responsive upregulation of downstream genes, simultaneously forming a molecular bridge between primary and specialized metabolisms. Though many studies have been conducted on the transcriptional regulation of stress-mediated primary or specialized metabolism genes, but not much data is available with regard to cis-element signatures and transcription factors that simultaneously modulate both pathway genes. Hence, our major focus would be to present a comprehensive analysis of the stress-mediated interconnection between primary and specialized metabolism genes via the interaction between different transcription factors and their corresponding cis-elements. In future, this study could be further utilized for the overexpression of the specific transcription factors that upregulate both primary and specialized metabolism, thereby simultaneously improving the yield and therapeutic content of plants.

“…Salinity resistance genes in tomato were identified in many studies and published in the Sol Genomics Network (SGN) database (SGN, 2015). Some of these genes encode transcription factors, which regulate many genes in response to stress, such as zinc finger homeodomain transcription factor family (ZFHD1) (Aoki et al, 2010) and abscisic acid response element-binding protein (AREB) (Orellana et al, 2010;Bastías et al, 2014). Osmolytes are among the genes induced under salinity stress.…”

To cite this paper: Almutairi, Z.M., 2016. Influence of silver nano-particles on the salt resistance of tomato (Solanum lycopersicum) during germination. AbstractSilver nanoparticles (AgNPs) have been implicated to enhance seed germination and plant growth, improve photosynthetic quantum efficiency and act as antimicrobial agents to manage plant diseases. The role of nanoparticles in the improvement of plant tolerance to environmental stresses such as drought and salinity remains unclear. In this study, we examined the effects of AgNP dose on the salt tolerance of tomato (Solanum lycopersicum L.) plants during germination. Tomato seeds were treated with different AgNP doses and germinated under salinity stress. Five concentrations of AgNPs (0.05, 0.5, 1.5, 2 and 2.5 mg L -1 ) and two levels of NaCl (150 and 100 mM) were tested. Seed germination and seedling growth of tomato plants were markedly inhibited by salt stress, and this effect was alleviated by exposure to AgNPs. The germination percentage, germination rate, root length and seedling fresh and dry weight of tomato were improved after exposure to AgNPs under NaCl stress. The expression of salt stress genes was investigated by semi-quantitative RT-PCR. Of the examined salt stress genes, four genes, AREB, MAPK2, P5CS and CRK1, were up-regulated by AgNPs under salt stress, and three genes, TAS14, DDF2 and ZFHD1, were down-regulated in response to AgNPs. The gene expression patterns associated with AgNP exposure also suggest the potential involvement of AgNPs in response to stress, indicating that they might be useful for improving plant tolerance to salinity.
