Abstract excerpt
KEY MESSAGE: We mapped the QTLs for FAAs in edamame seeds and identified TOF11 as the causal gene. TOF11 loss-of-function accelerates flowering/maturation and increases FAAs during the edamame stage. The free amino acid (FAA) content in edamame seeds is a determinant of sweetness and umami taste; however, its genetic regulation remains unclear. Therefore, in this study, to elucidate the genetic basis of FAA...
