Gene Details:

• MSU gene ID: LOC_Os09g38580
• RAPdb gene ID: Os09g0558300
• Gene Symbol: CDS1 OsCNGC9
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• We show that OsCNGC9 mediates PAMP-induced Ca2+ influx and that this event is critical for PAMPs-triggered ROS burst and induction of PTI-related defense gene expression.
• We further show that a PTI-related receptor-like cytoplasmic kinase OsRLCK185 physically interacts with and phosphorylates OsCNGC9 to activate its channel activity.
• In addition, transcription of OsCNGC9 is activated by a rice dehydration responsive element binding transcription factor, OsDREB1A.
• Transcriptional Activation and Phosphorylation of OsCNGC9 Confer Enhanced Chilling Tolerance in Rice.
• We showed that the loss-of-function mutant of OsCNGC9 is defective in cold-induced calcium influx and more sensitive to prolonged cold treatment while OsCNGC9 overexpression confers enhanced cold tolerance.
• Together, our results suggested that OsCNGC9 enhances chilling tolerance in rice through regulating cold-induced calcium influx and cytoplasmic calcium elevation.
• Mechanistically, we showed that in response to chilling stress, OsSAPK8, a homolog of Arabidopsis thaliana OST1, phosphorylates and activates OsCNGC9 to trigger Ca2+ influx.
