Gene Details:

• Gene ID: Glyma.13G329700
• Gene Symbol: TOE4b
• Gene Name: transcription factor 4
• Genome: Wm82.a4.v1
• Species: Glycine max

Functional Descriptions:

• This new transcription factor, which we named TOE4b, is localized in the nucleus.
• The gene-edited TOE4b knockout mutant exhibited earlier flowering, conversely, 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 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.
• 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.
