图1 籽粒发育动态及授粉后不同时期野生型籽粒和突变型籽粒对比 A: 杂合果穗; B: 30 DAP时突变型籽粒和野生型籽粒对比; C: 授粉后不同时期野生型与突变型籽粒发育动态; D~E: 50颗野生型和突变型籽粒不同时期干重、鲜重的变化; F: 20颗野生型和突变型籽粒不同时期体积的变化。WT: 野生型籽粒; dek101: 突变体籽粒。A~C图标尺为1 cm。**, 突变型籽粒与野生型相比在统计学上有极显著差异 (P < 0.01)。DAP: 授粉后天数。

Fig. 1 Overview of the kernel development dynamics and comparison between wild-type and mutant kernels in different days after pollination A: Ear performance of heterozygous plants; B: Comparison of dek101 and wild-type kernels at 30 days after pollination; C: Developmental dynamics of wild-type and mutant kernels in different time series; D-E: Dynamics changes in dry weight, fresh weight of 50 wild-type and dek101 kernels at different stages. F: Dynamics changes in volume of 20 wild-type and dek101 kernels at different stages. WT: wild type; dek101: mutant. Bar in A-C: 1 cm. **, indicates extremely significant difference of expression in specific tissues between dek101 and WT (P < 0.01). DAP: days after pollination.
