“…Moreover, EREBPs play an important role in responding to phytohormone, pathogen attack and environmental stresses such as cold, drought and high salt content (9). DREBs such as OsDREB from Oryza sativa and DREB1 from Arabidopsis are implicated in the response to abiotic stress (10,11). AtDREB1A is only expressed at low temperatures, while AtDREB2A responds to drought and high salinity (12).…”

We investigated the expression pattern of dehydration responsive element-binding protein-3 in tomato under different abiotic stresses. Full length LeDREB3 cDNA was isolated from tomato plant, followed by phylogenetic analysis based on deduced amino acid sequences that revealed significant sequence similarity to DREB proteins belonging to diverse families of plant species. Southern blot analysis showed duplicate copies of LeDREB3 in the tomato genome while organ-specific expression profiling indicated constitutive expression of LeDREB3 in all tested organs, which was particularly strong in flower. LeDREB3 expression was significantly induced by Nacl, drought, low temperature and H2O2. Moreover,

“…Salt tolerance is a complex trait involving the function of many genes (Flowers, 2004;Foolad, 2004). In fact, the exploitation of natural genetic variations and the generation of transgenic plants introducing novel genes or altering expression levels of the existing genes are being used to improve salt tolerance (Austin, 1993;Jain and Selvaraj, 1997;Yeo, 1998;Hasegawa et al, 2000;Park et al, 2001;Xiong and Yang, 2003;Guo et al, 2004;Davletova et al, 2005;Dana et al, 2006;Hong and Hwang, 2006). In legumes, salt stress significantly limits productivity because of its adverse effects on the growth of the host plant and its symbiotic interactions.…”

“…TFs are crucial elements for the regulation of development and adaptation to abiotic stresses in plants, and the overexpression of specific TFs leads to increased tolerance to abiotic stress, such as salt stresses (Kasuga et al, 1999;Winicov and Bastola, 1999;Winicov, 2000;Guo et al, 2004;Kim et al, 2004;Mukhopadhyay et al, 2004;Davletova et al, 2005). We have previously studied the MtZpt2 TFIIIA-related TFs (MtZpt2-1 and MtZpt2-2) in the 108-R genotype (Merchan et al, 2003(Merchan et al, , 2007.…”

Differential Expression of the TFIIIA Regulatory Pathway in Response to Salt Stress between Medicago truncatula Genotypes

Soil salinity is one of the most significant abiotic stresses for crop plants, including legumes. These plants can establish root symbioses with nitrogen-fixing soil bacteria and are able to grow in nitrogen-poor soils. Medicago truncatula varieties show diverse adaptive responses to environmental conditions, such as saline soils. We have compared the differential root growth of two genotypes of M. truncatula (108-R and Jemalong A17) in response to salt stress. Jemalong A17 is more tolerant to salt stress than 108-R, regarding both root and nodulation responses independently of the nitrogen status of the media. A dedicated macroarray containing 384 genes linked to stress responses was used to compare root gene expression during salt stress in these genotypes. Several genes potentially associated with the contrasting cellular responses of these plants to salt stress were identified as expressed in the more tolerant genotype even in the absence of stress. Among them, a homolog of the abiotic stress-related COLD-REGULATEDA1 gene and a TFIIIA-related transcription factor (TF), MtZpt2-1, known to regulate the former gene. Two MtZpt2 TFs (MtZpt2-1 and MtZpt2-2) were found in Jemalong A17 plants and showed increased expression in roots when compared to 108-R. Overexpression of these TFs in the sensitive genotype 108-R, but not in Jemalong A17, led to increased root growth under salt stress, suggesting a role for this pathway in the adaptive response to salt stress of these M. truncatula genotypes.

“…ERF family have single AP2/ERF domain and carry crucial function in ethylene signal transduction in response to environmental stresses (Takagi and Shinshi, 1995; Dubouzet et al, 2003), pathogen related stimuli and regulated pathogenesis-related gene expression (Zarei et al, 2011). Recently, overexpression of ERF gene was studied in rice (Zhang and Huang, 2010), tomato and tobacco under saline and drought environment (Guo et al, 2004;Zhang and Huang, 2010). In RAV, in addition to one AP2/ERF domain, there is another DNA binding B3-like domain, which is plant specific binding and also present in other transcription factors (Kagaya, et al, 1999).…”

Abstract. Transcription factors are usually considered as key player for gene regulation. Among various transcription factor families, AP2/ERF superfamily is well known for regulating various stress responses in plants. The family encompasses AP2/ERF domain, which is involved in DNA binding comprises of about 60 to 70 amino acids. To date, there is no detailed report presenting structural and functional prediction of ERF genes in Zea mays (L.). The current study presents a comprehensive genome-wide analysis of 105 ERF genes in maize (ZmERF) using several computational techniques. We performed phylogenetic analysis, conserved motif analysis, chromosomal localization, gene structure analysis and multiple sequence alignment of ERF genes. The phylogenetic analysis led to classification of these ERF members into 10 major groups and various subgroups and inferred evolutionary relationship among the groups on the basis of various protein motifs as well as intron/exon structure. The mapping of ERF genes on 10 maize chromosomes revealed their existence on all chromosomes with most number (17 genes) carried by chromosome 1 and least number (8 genes) found on chromosome 3. Interestingly, a very limited intron frequency was resulted in gene structure analysis. Gene ontology analysis concludes that ZmERF are involved in responses to various stresses including both biotic and abiotic. The results of the present study provide important structural information to design functional analyses of the ERF genes in Z. mays.
