DNA Sequence that Confers Aphid Resistance in Soybeans (Rag2)
- 详细技术说明
- Researchers at the University of Illinois and USDA – Agricultural Research Service have identified a gene that can confer aphid resistance for soybeans.
- *Abstract
-
Soybean aphid is an invasive insect pest that was first discovered in North America in 2000. Since then, these aphids have become a significant pest in the soybean producing regions of the northern USA and southern Canada. Currently, millions of acres of fields are sprayed with insecticide each year, which is both costly and has potential environmental implications. Researchers at the University of Illinois and USDA – Agricultural Research Service have identified a gene that can confer aphid resistance for soybeans. This gene, Rag2, offers a non-GMO way to confer aphid resistance.
DESCRIPTION/DETAILS
The Rag2 gene was identified through fine-mapping techniques in an aphid-resistant strain andmaps to a novel chromosomal locus. Identification of the specific resistancegene allows researchers to identify and breed Rag2-containing soybean strainsthrough various methods including marker-assisted selection.
APPLICATIONS
- Cultivation of aphid-resistant soybeans
BENEFITS
- Rapid, straight-forward introgression of Rag2 into susceptible soybean cultivars by marker-assisted selection.
- Ability to identify aphid-resistant germplasm that has new resistance genes
- Prevents successful aphid colonization on plants by reducing aphid multiplication, survival, lifespan, and development of nymphs to adults.
- Conventional, non-GMO, breeding can be used
- Is a safe alternative to insecticide use
