Gene Details:

• Gene ID: Glyma.20G085100
• Gene Symbol: POWR1
• Gene Name: CCT domain-containing protein
• Genome: Wm82.a4.v1
• Species: Glycine max

Functional Descriptions:

• POWR1 is a domestication gene pleiotropically regulating seed quality and yield in soybean.
• A CCT gene, POWR1, underlies a large-effect protein/oil QTL.
• POWR1 pleiotropically controls these traits likely through regulating seed nutrient transport and lipid metabolism genes.
• POWR1 is also a domestication gene. We hypothesize that the TE insertion allele is exclusively fixed in cultivated soybean due to selection for larger seeds during domestication, which significantly contributes to shaping soybean with increased yield/seed weight/oil but reduced protein content.
• We demonstrate that a CCT gene, POWR1, underlies a large-effect protein/oil QTL. A causative TE insertion truncates its CCT domain and substantially increases seed oil content, weight, and yield while decreasing protein content.
