Subfunctionalisation and self-repression of duplicated E1 homologues finetunes soybean flowering and adaptation
Abstract Soybean click here is a photoperiod-sensitive staple crop.Its photoperiodic flowering has major consequences for latitudinal adaptation and grain yield.Here, we identify and characterise a flowering locus named Time of flower 4b (Tof4b), which encodes E1-Like b (E1Lb), a homologue of the key soybean floral repressor E1.Tof4b protein physic
