- Key message
- Induced expression of SAPK4 resulted in improved germination, growth and development under salt stress both in seedlings and mature plants
- CONCLUSION: Our results show that SAPK4 regulates ion homeostasis and growth and development under salinity and suggest function of SAPK4 as a regulatory factor in plant salt stress acclimation
- SAPK4-regulated genes with functions in ion homeostasis and oxidative stress response were identified: the vacuolar H+-ATPase, the Na+/H+ antiporter NHX1, the Cl- channel OsCLC1 and a catalase
- Here, we address a specific role of spermidine during high salt stress by studying its interaction with OSPDK, a sucrose nonfermenting 1-related protein kinase2 (SnRK2)-type serine/threonine protein kinase SAPK4 homolog in indica rice
- In this study, we characterized the function of the sucrose nonfermenting 1-related protein kinase2 (SnRK2) SAPK4 in the salt stress response of rice
- To examine the role of SAPK4 in salt tolerance we generated transgenic rice plants with over-expression of rice SAPK4 under control of the CaMV-35S promoter
- In response to salt stress, the SAPK4-overexpressing rice accumulated less Na+ and Cl- and showed improved photosynthesis
- In this report, we demonstrate that spermidine mediates in vitro phosphorylation of OSBZ8, a bZIP class of ABRE-binding transcription factor, by OSPDK

- OsbZIP42, SAPK4~OSPDK, OsbZIP42 is a positive regulator of ABA signaling and confers drought tolerance to rice., The activation of OsbZIP42 depends on stress-/ABA-activated protein kinase 4 (SAPK4) and an additional ABA-dependent modification of OsbZIP42
- OsbZIP42, SAPK4~OSPDK, OsbZIP42 is a positive regulator of ABA signaling and confers drought tolerance to rice., Although the full-length OsbZIP42 protein did not, the N-terminus of the protein interacted with SAPK4
- OsbZIP42, SAPK4~OSPDK, OsbZIP42 is a positive regulator of ABA signaling and confers drought tolerance to rice., Our results suggest that the activation of OsbZIP42 by SAPK4 requires another ABA-dependent modification of OsbZIP42
