- Key message
- In rice (Oryza sativa), a short-day plant, Heading date6 (Hd6) encodes a CK2alpha subunit that delays flowering time under long-day conditions
- Here, we demonstrate that control of flowering time in rice by the Hd6 CK2alpha subunit requires a functional Hd1 gene (an Arabidopsis CONSTANS ortholog) and is independent of the circadian clock mechanism
- The circadian clock component CIRCADIAN CLOCK ASSOCIATED1 (CCA1) is a CK2 target in Arabidopsis, where it influences photoperiodic flowering
- These findings imply that the role of CK2 in flowering-time regulation in higher plants has diversified during evolution

- Hd6~CK2, OsDof12~OsCDF1, OsMADS50 and OsMADS56 function antagonistically in regulating long day LD-dependent flowering in rice, On the other hand, mRNA levels of OsGI, Hd1, OsId1, OsDof12, Ghd7, Hd6 and SE5 were unchanged
- Hd6~CK2, OsGI, OsMADS50 and OsMADS56 function antagonistically in regulating long day LD-dependent flowering in rice, On the other hand, mRNA levels of OsGI, Hd1, OsId1, OsDof12, Ghd7, Hd6 and SE5 were unchanged
- Hd6~CK2, OsLHY~OsCCA1, The role of casein kinase II in flowering time regulation has diversified during evolution, This lack of control of the circadian clock by Hd6 CK2alpha might be due to the presence of glutamate in OsLHY (a CCA1 ortholog in rice) instead of the serine at the corresponding CK2 target site in CCA1
- Hd6~CK2, OsLHY~OsCCA1, The role of casein kinase II in flowering time regulation has diversified during evolution, We also demonstrated that the other conserved CK2 target sites in OsLHY conferred robust rhythmic expression of OsLHY-LUC under diurnal conditions

- CKI~EL1~Hd16, Hd6~CK2, Fine-tuning of the setting of critical day length by two casein kinases in rice photoperiodic flowering., Here, we identified two casein kinase genes, Hd16 and Hd6, which modulate the expression of florigen genes within certain restricted ranges of photoperiod, thereby fine-tuning the critical day length
- CKI~EL1~Hd16, Hd6~CK2, Fine-tuning of the setting of critical day length by two casein kinases in rice photoperiodic flowering., Utilization of the natural variation in Hd16 and Hd6 was only found among temperate japonica cultivars adapted to northern areas
- Hd6~CK2, OsCOL4, A Combination of Long-Day Suppressor Genes Contributes to the Northward Expansion of Rice , Here, we report the analysis of genetic variation in eight long-day flowering suppressor genes (Hd1, DTH8, Ghd7, OsCOL4, DTH7, Hd6, Se5, and PhyB) and the phylogenetic relationship of eight genes
- Hd6~CK2, OsCOL4, A Combination of Long-Day Suppressor Genes Contributes to the Northward Expansion of Rice , Genetic variations in DTH8, Ghd7, Hd1, DTH7, PhyB, and OsCOL4 are correlated with differences in heading date and the correlation between the genetic diversity of Hd6 and Se5 and rice heading data are weak
- Hd6~CK2, OsHBP1b~OsTGA5, Phosphorylation of OsTGA5 by casein kinase II compromises its suppression of defense-related gene transcription in rice., Importantly, we showed that the nucleus-localized casein kinase II (CK2) complex interacts with and phosphorylates OsTGA5 on Ser-32, which reduces the affinity of OsTGA5 for the JIOsPR10 promoter, thereby alleviating the repression of JIOsPR10 transcription and increasing rice resistance
