Figure 2. SERF1 Is Specifically Induced by Salt Stress and H2O2 Treatment and Is Expressed in the Vascular Tissues of Roots and Leaves..[1].
Function
- ERF1 Regulates Reactive Oxygen Species–Dependent Signaling during the Initial Response to Salt Stress in Rice
- 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.
- SERF1 is a phosphorylation target of MAPK5, resulting in enhanced transcriptional activity of SERF1 toward its direct target genes.
- 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.
Expression
- Application of ABA or mannitol did not affect the expression of SERF1.
- By contrast, as observed for salt stress, H2O2 treatment caused an upregulation of SERF1 within 30 min exclusively in roots, albeit an induction was also observed after 3 h of treatment.
- Rice plants expressing a b-glucuronidase (GUS) reporter gene fused to a 1-kb promoter of SERF1 exhibited GUS activity in the vascular cylinder of the root and the main and commissural veins of leaves (Figure 2B).
Subcellular localization
- Although SERF1 does not contain a known nuclear localization signal, stable transformation of rice plants with a construct encoding a CFP-tagged version of SERF1 revealed nuclear localization of SERF1 in leaf epidermal cells (Figure 2C).
