Gene Details:

• MSU gene ID: LOC_Os03g55389
• RAPdb gene ID: Os03g0762000
• Gene Symbol: Hd6 CK2
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• 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.
