Crispr
Soybeans grown from seeds with this trait could deliver better oil and nutritional profiles without farmers sacrificing the harvest size they depend on.
Researchers snipped a tiny piece out of a soybean gene using a molecular editing tool called CRISPR. The edited plants still produced normal amounts of seeds at normal sizes, but the seeds themselves had different internal qualities. This kind of targeted change is a shortcut for plant breeders trying to improve the nutritional or processing value of soybeans without accidentally making the plant less productive.
Key Findings
A 36-base-pair in-frame deletion in the GmOIL2 gene was created using CRISPR without disrupting plant fertility
Seed weight was maintained in plants carrying the new allele, decoupling quality traits from yield penalties
The allele alters seed-related traits, providing a genetic resource for soybean quality improvement programs
chevron_right Technical Summary
Scientists used CRISPR to create a specific soybean gene variant that improves seed quality traits without reducing fertility or seed size. This gives breeders a precise tool to develop better soybeans without the usual trade-offs.

Gene editing removes 97% of celiac-triggering proteins from bread wheat
It could mean that people with celiac disease — roughly 1 in 100 worldwide — may one day safely eat bread made from real wheat, without sacrificing the taste...
The soybean, soy bean, or soya bean is a species of legume native to East Asia, widely grown for its edible bean. Soy is a staple crop, the world's most grown legume, and an important animal feed.
