Other examples for stress related genes which are preferentially expressed in the vascular tissue are the drought, salt and cold stress regulated potassium channel gene GORK (Becker et al 2003), freezing tolerance associated proteins (Houde et al 1995) and rice C2H2-type zinc finger protein playing a role in salt tolerance (Huang et al 2007). The novel stress responsive gene HIPP26 also follows this pattern of preferential expression in the sensitive vascular tissue.…”

HIPP26 from Arabidopsis thaliana belongs to a novel class of plant proteins, characterized by a heavy metal associated domain and an additional isoprenylation motif. It is induced during cold, salt and drought stress. The nuclear localization of HIPP26, predicted by a NLS motif, could be confirmed in onion epidermal cells overexpressing GFP-HIPP26. Experiments with modified HIPP26 indicate that the isoprenylation plays a role in the spatial distribution in the nucleus. Using promoter-GUS constructs, a tissue specific expression pattern of HIPP26 could be shown, with high expression in the vascular tissue. By a yeast-two-hybrid approach a strong interaction of HIPP26 with the zinc finger homeodomain transcription factor ATHB29, which is known to play a role in dehydration stress response could be detected. This was confirmed by GST pull-down assays. When using a modified HIPP26 lacking the two central cysteines of the heavy metal associated domain, ATHB29 was not bound in the GST pull-down assay, indicating that this structure is necessary for the interaction. Further yeast-two-hybrid analyses testing interaction of different members of the HIPP family with related zinc finger transcription factors revealed a specific interaction of ATHB29 with several HIPP proteins. A functional relationship between HIPP26 and ATHB29 is also indicated by experiments with mutants of HIPP26 showing altered expression levels of such genes known to be regulated by ATHB29.

“…In addition to salt stress, both TF genes were H 2 O 2 inducible. The transcript levels of the zinc-finger TF genes ZFP179, ZFP182, and ZFP252 (Huang et al, 2007;Xu et al, 2008;Sun et al, 2010) were enhanced in wild-type roots after 30 min of salt stress. However, no significant induction was observed in roots of serf1 and SERF1 knockdown lines.…”

SALT-RESPONSIVE ERF1 Regulates Reactive Oxygen Species-Dependent Signaling during the Initial Response to Salt Stress in Rice

Early detection of salt stress is vital for plant survival and growth. Still, the molecular processes controlling early salt stress perception and signaling are not fully understood. Here, we identified SALT-RESPONSIVE ERF1 (SERF1), a rice (Oryza sativa) transcription factor (TF) gene that shows a root-specific induction upon salt and hydrogen peroxide (H 2 O 2 ) treatment. Loss of SERF1 impairs the salt-inducible expression of genes encoding members of a mitogen-activated protein kinase (MAPK) cascade and salt tolerance-mediating TFs. Furthermore, we show that SERF1-dependent genes are H 2 O 2 responsive and demonstrate that SERF1 binds to the promoters of MAPK KINASE KINASE6 (MAP3K6), MAPK5, DEHYDRATION-RESPONSIVE ELEMENT BINDING2A (DREB2A), and ZINC FINGER PROTEIN179 (ZFP179) in vitro and in vivo. SERF1 also directly induces its own gene expression. In addition, SERF1 is a phosphorylation target of MAPK5, resulting in enhanced transcriptional activity of SERF1 toward its direct target genes. In agreement, plants deficient for SERF1 are more sensitive to salt stress compared with the wild type, while constitutive overexpression of SERF1 improves salinity tolerance. We propose that SERF1 amplifies the reactive oxygen species-activated MAPK cascade signal during the initial phase of salt stress and translates the salt-induced signal into an appropriate expressional response resulting in salt tolerance.

“…Several EAR motif-containing ZF proteins play an important role in regulating defense responses to drought, saline, or cold conditions [93]. Altering the expression of the genes encoding C2H2-type transcription improved stress tolerance in Arabidopsis, rice, tobacco, and petunia [93][94][95][96]. Recently, a chickpea C2H2 ZF protein named CaZF was shown to mediate osmotolerance in budding yeast as well as improved salinity response in transgenic tobacco [97].…”

Climate Change and Plant Abiotic Stress Tolerance

View full text Add to dashboard Cite

Climate change and the associated environmental constraints have created a challenge to sustain food security and biodiversity globally. The response to adverse environments is a complex process and plants integrate several approaches that allow them to withstand climatic restraints, depending on the timing and length. Changes at the transcriptional level of various genes transduce cellular signals for the synthesis of necessary metabolites. Transcription factors have the principal role for the efficient adaptation capacity of the plants, and present an attractive target category for manipulation and gene regulation. As many biological processes in plants are regulated at the level of transcription, understanding transcription factor function is an important step towards understanding plant responses to environmental conditions. Among them, numerous transcription factors belonging to several large transcription factor families, such as AP2/ERF, bZIP, MYB, MYC, Cys2His2 zinc finger, WRKY, and NAC, have been shown as stress-responsive proteins. They act both by an abscisic acid-dependent and -independent manner, and through their interaction with respective cis-elements of their target genes, play crucial roles in recuperating plant stress tolerance. We highlight the considerable biotechnological progress made towards understanding the molecular stress responses of plants using important transcription factor families. The progress of their practical and application value in crop improvement through genetic engineering is also discussed. 22.
