Gene Details:

• Gene ID: Glyma.05G194400
• Gene Symbol: GmUVR8b
• Gene Name: UV-B receptor b
• Genome: Wm82.a4.v1
• Species: Glycine max

Functional Descriptions:

• We clarify a fine-tuning mechanism in response to ultraviolet B (UV-B) irradiation and rhizobia infection, involving GmUVR8-dependent UV-B perception and GmSTF3/4-GmMYB12-GmCHS-mediated (iso)flavonoid biosynthesis for soybean nodule formation.
• GmUVR8 receptor-perceived UV-B signal triggered R2R3-MYB transcription factors GmMYB12-dependent flavonoid biosynthesis separately in shoot and root. In shoot, UV-B-triggered flavonoid biosynthesis relied on GmUVR8a, b, c receptor-dependent activation of GmMYB12L-GmCHS8 (chalcone synthase) module.
• In shoot, UV-B-triggered flavonoid biosynthesis relied on GmUVR8a, b, c receptor-dependent activation of GmMYB12L-GmCHS8 (chalcone synthase) module. In root, UV-B signaling distinctly promotes the accumulation of the isoflavones, daidzein, and its derivative coumestrol, via GmMYB12B2-GmCHS9 module, resulting in hypernodulation.
• Demonstrate that the UV-B receptors GmUVR8a, b, and c perceive UV-B signal in soybean shoots and promote isoflavone accumulation in roots, to stimulate nodule formation in response to UV-B irradiation.
