Gene Details:

• Gene ID: Bra004503
• Gene Symbol: BrCCA1
• Gene Name: CIRCADIAN AND CLOCK ASSOCIATED 1
• Genome:
• Species: Brassica rapa

Functional Descriptions:

• Vernalization-mediated demethylation of BrCKA2 (casein kinase II α-subunit) and BrCKB4 (casein kinase II β-subunit) shorten the period of the clock gene BrCCA1 (circadian clock associated 1) in Brassica rapa.
• Virus-induced gene silencing (VIGS) of BrCKA2 and BrCKB4 in B. rapa resulted in no change to the period of BrCCA1 (circadian clock associated 1) and a 1-week late flowering time.
• Demonstrated that increased levels of BrCKA2 and BrCKB4 in vernalized B. rapa confer elevated CK2 activity, resulting in a shortened period of the clock gene BrCCA1, which plays an important role in perceiving photoperiod in plants.
• BrCCA1 was detected following silencing of BrCKA2 and BrCKB4, demonstrating that vernalization affects clock genes in B. rapa.
