Gene Details:

• Gene ID: Glyma.08G183500
• Gene Symbol: GmSWEET10b
• Gene Name: Bidirectional sugar transporter SWEET
• Genome: Wm82.a4.v1
• Species: Glycine max

Functional Descriptions:

• Simultaneous changes in seed size, oil content and protein content driven by selection of SWEET homologues during soybean domestication.
• GmSWEET10b was found to be functionally redundant with its homologue GmSWEET10a and to be undergoing selection in current breeding, leading the the elite allele GmSWEET10b, a potential target for present-day soybean breeding.
• Both GmSWEET10a and GmSWEET10b were shown to transport sucrose and hexose, contributing to sugar allocation from seed coat to embryo, which consequently determines oil and protein contents and seed size in soybean.
• We conclude that past selection of optimal GmSWEET10a alleles drove the initial domestication of multiple soybean-seed traits and that targeted selection of the elite allele GmSWEET10b may further improve the yield and seed quality of modern soybean cultivars.
