Note: T, H, and F₁ refer to T449, H1, and hybrid (F₁), respectively. DEG_PP refers to DEG between T449 and H1, DEG_FP refers to DEG between hybrid and its parents. DEG_FPU denotes the unique numbers of DEG_FP that were belong to F₁ only, and DEG_C denotes the overlapped genes between DEG_PP and DEG_FP. L1 and P1 represent flag leaves and anthers at meiosis stage, respectively. L2, P2, E2 and Z2 represent flag leaves, anther, embryo sac and leaf sheath at pre-flowering stage, respectively. L3, P3 and Z3 represent flag leaves, grain and leaf sheath at three days after flowering, respectively
