Gene Details:

• Gene ID: TraesCS1B02G113100
• Gene Symbol: TaPGS1-1B-2
• Gene Name: T. aestivum POSITIVE REGULATOR of GRAIN SIZE 1
• Genome: Chinese_Spring1.0
• Species: Triticum aestivum

Functional Descriptions:

• TaPGS1 was bound directly to the E-box motif at the promoter of the PLATZ TF genes TaFl3 and OsFl3 and positively regulated their expression in wheat and rice.
• We identified the bHLH protein TaPGS1 (T. aestivum Positive Regulator of Grain Size 1) specifically expressed in the seeds at 5–20days post-anthesis in wheat.
• Our results reveal that TaPGS1 functions as a valuable trait-associated gene for improving cereal grain yield.
• Overexpression (OE) of TaPGS1 in wheat and rice resulted in altered expression levels of seed-development-related genes and increased grain weight and grain size in field tests.
• TaPGS1 increased grain weight and size in wheat and rice.
