Gene Details:

• Gene ID: Zm00001eb057490
• Gene Symbol: ZmPHYC1
• Gene Name: phytochromeC1
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• Double knockout mutants of ZmPHYC1 and ZmPHYC2 created using the CRISPR/Cas9 technology display a moderate early-flowering phenotype under long-day conditions, whereas ZmPHYC2 overexpression plants exhibit a moderately reduced plant height and ear height.
• ZmPHYC1 and ZmPHYC2 can be used as potential targets for genetic engineering of maize to improve flowering time and plant architecture suitable for high-density planting.
• ZmPHYC1 zmphyC2 double knockout mutants display an early-flowering phenotype under LD conditions.
• we examined the expression patterns of ZmPHYC1 and ZmPHYC2 and found that ZmPHYC1, but not ZmPHYC2, is highly expressed in leaves and is regulated by the circadian clock.
• Together, these results provided new insight into the function of ZmPHYCs and guidance for breeding high-density tolerant maize cultivars.
