Gene Details:

• Gene ID: Cla97C04G070940
• Gene Symbol: ClLCYB
• Gene Name: lycopene β-cyclase
• Genome: [watermelon reference v2 genome](http://cucurbitgenomics.org/organism/21; Zheng et al., 2019)
• Species: Citrullus lanatus

Functional Descriptions:

• Identified a lycopene β-cyclase (ClLCYB) gene that controls the flesh color of watermelon. Down-regulation of ClLCYB caused the flesh color to change from pale yellow to red, and ClLCYB overexpression in the red-fleshed line caused the flesh color to change to orange.
• Analysis of ClLCYB single-nucleotide polymorphisms using 211 watermelon accessions with different flesh colors revealed that two missense mutations between three haplotypes (ClLCYB red, ClLCYB white, and ClLCYB yellow) were selected and largely fixed in domesticated watermelon.
• Selection Pressure on ClLCYB Underlies the Domestication of Red-Fleshed Watermelon.
• These results indicate that natural missense mutations within ClLCYB influence ClLCYB protein abundance and have contributed to the development of red flesh color in domesticated watermelon.
