Gene Details:

• Gene ID: Glyma.10G221500
• Gene Symbol: E2 GIa GI3
• Gene Name: Gigantea gene 3
• Genome: Wm82.a4.v1
• Species: Glycine max

Functional Descriptions:

• A genome-wide association study to identify a major salt-tolerance locus controlled by E2, an ortholog of Arabidopsis thaliana GIGANTEA (GI).
• Loss of E2 function not only shortened flowering time and maturity, but also enhanced salt-tolerance in soybean.
• E2 delayed soybean flowering by enhancing the transcription of the core flowering suppressor gene E1, thereby repressing Flowering Locus T (FT) expression.
• An E2 knockout mutant E2CR displayed reduced accumulation of reactive oxygen species (ROS) during the response to salt stress by releasing peroxidase, which functions in ROS scavenging to avoid cytotoxicity.
• Evolutionary and population genetic analyses also suggested that loss-of-function E2 alleles have been artificially selected during breeding for soybean adaptation to high-latitude regions with greater salt stress.
