Molecular mechanism of E1/E1Lb editing manipulating soybean flowering and determinacy. E1/E1Lb editing breaks the equilibrium balance of soybean flowering regulation under long‐day conditions. The flowering‐promoting genes FT2a and FT5a up‐regulated and flowering‐inhibiting genes FT1a and FT4 down ‐ regulated to series of different expression level that is caused by E1/E1Lb NLS editing, consequently trigger AP1 gene expression increasing to a certain level and switching the soybean development to reproductive growth. Meanwhile, high FT5a expression represses key gene of soybean determinacy DT1, causing stem growth termination and plant height decreasing.
