Study suggests new targets for improving soybean oil content

Scientists working to increase soybean oil content tend to focus their efforts on genes known to impact the plant’s seeds, but a Purdue University study shows that genes affecting other plant parts deserve more attention.

Wild-type soybeans contain bloom, a powdery substance originating in the pod that can coat seeds. This trait makes the seeds less visible and is believed to be advantageous for their long-term survival in natural environments. But the bloom is enriched with allergens and can be harmful for animals and people if ingested. People domesticating soybeans selected a naturally occurring mutation that makes soybean seeds shiny through eliminating bloom. For the full story, click here.
