Gene Details:

• Gene ID: Glyma.13G329700
• Gene Symbol: TOE4b
• Gene Name: The AP2/ERF transcription factor
• Genome: Wm82.a4.v1
• Species: Glycine max

Functional Descriptions:

• The AP2/ERF transcription factor TOE4b regulates photoperiodic flowering and grain yield per plant in soybean.
• TOE4b overexpression delayed flowering time. TOE4b is directly bound to the promoters and gene bodies of the key flowering integration factor genes FT2a and FT5a to inhibit their transcription.
• TOE4b overexpression lines in field trials not only showed late flowering but also altered plant architecture, including shorter internode length, more internodes, more branches and pod number per plant, and finally boosted grain yield per plant by 60% in Guangzhou and 87% in Shijiazhuang.
• Our findings therefore identified TOE4b as a pleiotropic gene to increase yield potential per plant in soybean, and these results provide a promising option for breeding a soybean variety with an idealized plant architecture that promotes high yields.
