Gene Details:

• Gene ID: Cs3g20450
• Gene Symbol: CsSGRb
• Gene Name: STAY-GREEN
• Genome: C. sinensis genomic database
• Species: Citrus sinensis

Functional Descriptions:

• The comparison of transcriptomic and genomic data from multiple genotypes and plant sectors revealed an underlying lesion in the gene encoding STAY-GREEN (SGR) protein, which simultaneously regulates carotenoid biosynthesis and chlorophyll degradation.
• The carotenoid and chlorophyll regulatory activities could be uncoupled in the case of certain SGR alleles in citrus and thus we propose a model for the molecular mechanism underlying the brown flavedo phenotype.
• CsSGR function in regulating carotenoid biosynthesis.
• CsSGRb, which encodes a truncated protein that lacks the chlorophyll-degradation activity, still maintains the ability to interact with PSY and inhibit carotenoid accumulation.
