Molecular and geographic evolutionary support for the essential role of GIGANTEAa in soybean domestication of flowering time

摘要

BackgroundFlowering time is a domestication trait of Glycine max and varies in soybeans, yet, a gene for flowering time variation has not been associated with soybean domestication. GIGANTEA (GI) is a major gene involved in the control of flowering time in Arabidopsis, although three GI homologs complicate this model in the soybean genome.
