Abstract excerpt
Gene duplication is a major force for generating evolutionary novelties that lead to adaptations to environments. We previously identified two paralogs encoding phytochrome A (phyA), GmphyA1 and GmphyA2, in soybean, a paleopolyploid species. GmphyA2 is encoded by the E4 locus responsible for photoperiod sensitivity. In photoperiod insensitive lines, GmphyA2 is inactivated by the insertion of a retrotransposon in...
