Genetically modified soybean plants
By modifying the GmSWEET10b gene in soybean plants, especially by truncating its C-terminal region to encode an open-cavity GmSWEET10b protein, the problem of increasing oil content and seed size in existing technologies has been solved, and a stable increase in oil content and seed size has been achieved.

AI Technical Summary
Technical Problem
Existing technologies make it difficult to effectively increase soybean oil content and seed size through gene editing while avoiding yield loss.
Method used
By modifying the GmSWEET10b gene in soybean plants, particularly by truncating its C-terminal region, a modified GmSWEET10b protein with an open cavity is encoded, which improves sugar transport efficiency, thereby enhancing the oil content and seed size of soybean seeds.
Benefits of technology
It significantly increased soybean oil content and seed size without reducing yield in field trials at multiple locations and in different seasons, and exhibited stable genetic characteristics.

Abstract
This disclosure provides a method for increasing the oil content and / or seed size of soybean (Glycine max) plants, comprising modifying a polynucleotide encoding a GmSWEET10b protein in the plant genome such that the modified GmSWEET10b protein encoded by the modified polynucleotide has a truncated C-terminal region compared to the parental GmSWEET10b protein.
