- Key message
- OsRACK1A was found to follow a rhythmic expression profile under circadian conditions at both the transcription and the translation levels, although the expression was arrhythmic under salt stress
- Analysis of plant survival rates, fresh weight, proline content, malondialdehyde, and chlorophyll showed that suppression of OsRACK1A enhanced tolerance to salt stress
- We identified putative interactors of OsRACK1A, and found that OsRACK1A interacted with many salt stress-responsive proteins directly
- These results suggest that OsRACK1A is regulated by circadian rhythm, and involved in the regulation of salt stress responses
- Although the analysis of natural variation revealed no OsRACK1A variants that could avoid being targeted by UvCBP1, expression levels of OsRACK1A are correlated with field resistance against U
- Overproduction of OsRACK1A restores the OsRACK1A-OsRBOHB association and promotes OsRBOHB phosphorylation to enhance ROS production, conferring rice floral resistance to U
- Mechanistically, UvCBP1 interacts with the rice scaffold protein OsRACK1A and competes its interaction with the reduced nicotinamide adenine dinucleotide phosphate oxidase OsRBOHB, leading to inhibition of reactive oxygen species (ROS) production
- Connection
- OsRac1, OsRACK1A, Proteome analysis of detergent-resistant membranes DRMs associated with OsRac1-mediated innate immunity in rice, To examine the possible association of DRMs and OsRac1-mediated innate immunity, we used rice suspension-cultured cells transformed with myc-tagged wild-type (WT) OsRac1 and found that OsRac1 and RACK1A, an effector of OsRac1, shifted to the DRMs after chitin elicitor treatment
- OsRACK1A, OsRAR1, RACK1 functions in rice innate immunity by interacting with the Rac1 immune complex, RACK1A was shown to interact with the N terminus of NADPH oxidase, RAR1, and SGT1, key regulators of plant disease resistance
- OsRac1, OsRACK1A, RACK1 functions in rice innate immunity by interacting with the Rac1 immune complex, Rice contains two RACK1 genes, RACK1A and RACK1B, and the RACK1A protein interacts with the GTP form of Rac1
- OsRac1, OsRACK1A, RACK1 functions in rice innate immunity by interacting with the Rac1 immune complex, Rac1 positively regulates RACK1A at both the transcriptional and posttranscriptional levels
- OsRac1, OsRACK1A, RACK1 functions in rice innate immunity by interacting with the Rac1 immune complex, These results suggest that RACK1A functions in rice innate immunity by interacting with multiple proteins in the Rac1 immune complex
- OsRACK1A, RACK1B~OsWD40-122~OsRACK1B, RACK1 functions in rice innate immunity by interacting with the Rac1 immune complex, Rice contains two RACK1 genes, RACK1A and RACK1B, and the RACK1A protein interacts with the GTP form of Rac1

- OCP, OsRACK1A, Knockout of a papain-like cysteine protease gene OCP enhances blast resistance in rice., We prove that OCP, featuring cysteine protease activity, interacts with OsRACK1A (receptor for activated C kinase 1) and OsSNAP32 (synaptosome-associated protein of 32 kD) physically in vitro and in vivo, and they co-locate in the rice cytoplasm but cannot form a ternary complex
- OCP, OsRACK1A, Knockout of a papain-like cysteine protease gene OCP enhances blast resistance in rice., Therefore, OCP negatively regulates blast resistance in rice by interacting with OsRACK1A or OsSNAP32 and influencing the expression profiles of many resistance-related genes
