Gene Details:

• Gene ID: Zm00001eb172450
• Gene Symbol: ZmCCA1 ZmCCA1b cca1 mybr79
• Gene Name: circadian clock associated1
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• CIRCADIAN CLOCK ASSOCIATED1 gene of maize (ZmCCA1), an ortholog of CCA1 in Arabidopsis thaliana (AtCCA1).
• Overexpression of ZmCCA1 functionally delays flowering in Arabidopsis.
• ZmCCA1 transcripts accumulated in all tissues evaluated, with higher levels in tassels and ears.
• A detailed study of ZmCCA1 and ZmTOC1 confirmed that they are the key components in the maize circadian clock.
• ZmCCA1 encodes FLAVIN-BINDING, KELCH REPEAT, F-BOX1, is essential for photoperiodic-specific light signalling.
• ZmCCA1 may be a core component of the circadian clock in maize.
• Co-expression analysis and the diurnal expression rhythms of genes related to stress responses suggested that ZmCCT and one of the circadian clock core genes, ZmCCA1, are important nodes linking the photoperiod to stress tolerance responses under LD conditions.
• Additionally, ZmCCT and ZmCCA1 are important functional links between the circadian clock and stress tolerance.
