Key message

• OsHKT2;1~OsHKT1, OsCCT11~OsPRR73, Clock component OsPRR73 positively regulates rice salt tolerance by modulating OsHKT2;1-mediated sodium homeostasis, RNA sequencing and biochemical assays identified OsHKT2;1, encoding a plasma membrane-localized Na+ transporter, as a transcriptional target of OsPRR73 in mediating salt tolerance
• OsHKT2;1~OsHKT1, OsCCT11~OsPRR73, Clock component OsPRR73 positively regulates rice salt tolerance by modulating OsHKT2;1-mediated sodium homeostasis, Immunoprecipitation-mass spectrometry (IP-MS) assays further identified HDAC10 as nuclear interactor of OsPRR73 and co-repressor of OsHKT2;1
• OsHKT2;1~OsHKT1, OsCCT11~OsPRR73, Clock component OsPRR73 positively regulates rice salt tolerance by modulating OsHKT2;1-mediated sodium homeostasis, Consistently, H3K9ac histone marks at OsHKT2;1 promoter regions were significantly reduced in osprr73 mutant
• OsHKT2;1~OsHKT1, OsCCT11~OsPRR73, Clock component OsPRR73 positively regulates rice salt tolerance by modulating OsHKT2;1-mediated sodium homeostasis, Together, our findings reveal that salt-induced OsPRR73 expression confers salt tolerance by recruiting HDAC10 to transcriptionally repress OsHKT2;1, thus reducing cellular Na+ accumulation
• Ehd1, OsCCT11~OsPRR73, The transcriptional repressor OsPRR73 links circadian clock and photoperiod pathway to control heading date in rice, OsPRR73 bound to the promoters of the floral gene Ehd1 and the circadian gene OsLHY, and significantly suppressed their expression at dawn
• Ehd1, OsCCT11~OsPRR73, The transcriptional repressor OsPRR73 links circadian clock and photoperiod pathway to control heading date in rice, Therefore, OsPRR73 is involved in a feedback loop of the rice clock and connects the photoperiod flowering pathway by binding to the Ehd1 promoter in rice
