OsCIPK1 is a member of CIPK genes (CIPKs,calcineurin B-like protein interacting protein kinases).
- Interestingly, five OsCIPK genes, OsCIPK1, OsCIPK2, OsCIPK10, OsCIPK11 and OsCIPK12, were transcriptionally up-regulated after bacterial blight infection.
- OsCIPK1 is involved in the biotic stress.
- OsCBL7 and OsCBL8 interact strongly with OsCIPK1. OsCBL1 interacted strongly with OsCIPK1.
- By the RT-PCR-based cDNA cloning approach, 15 CIPK genes were cloned from stress-treated seedlings of Nipponbare. Among them, 10 genes (OsCIPK2, OsCIPK5, OsCIPK10, OsCIPK11, OsCIPK2, OsCIPK14, OsCIPK15, OsCIPK18, OsCIPK25 and OsCIPK26) were intron-less, and other five genes (OsCIPK1, OsCIPK3, OsCIPK7, OsCIPK23 and OsCIPK24) were intron-rich, consistent with the previous data.
- OsCIPK1 was transcriptionally up-regulated by Hg2+, the up-regulation occurred mainly in roots.
- OsCIPK01 and OsCIPK33 showed high expression in all tissues/organs except for the root, callus, and pollen.
- OsCIPK01 was induced by drought, PEG treatment and cold.
- Calcineurin B-like protein-interacting protein kinases(CIPKs) are a group of typical Ser/Thr protein kinases that mediate calcium signals. Some genes in the CIPK family of rice are involved in the responses to multiple abiotic stresses, whereas some genes of the family are responsive to specific stresses.
- The calcineurin B-like protein–CBL-interacting protein kinase (CBL–CIPK) signaling pathway in plants is a Ca2+-related pathway that responds strongly to both abiotic and biotic environmental stimuli. The CBL–CIPK system shows variety, specificity, and complexity in response to different stresses, and the CBL–CIPK signaling pathway is regulated by complex mechanisms in plant cells.
- Putative proline synthetase and transporter genes had significantly higher expression level in the transgenic plants than in the wild type. The differentially induced expression of OsCIPK genes by different stresses and the examples of improved stress tolerance of the OsCIPK transgenic rice suggest that rice CIPK genes have diverse roles in different stress responses and some of them may possess potential usefulness in stress-tolerance improvement of rice.
