图1 mi-ms-3和野生型表型 A: 野生型(左)和mi-ms-3 (右)雄穗表型, mi-ms-3花药不外露; B1~B2: 花药发育后期, 野生型和mi-ms-3花药横切片, mi-ms-3花药只有2个药室; C1~C4: mi-ms-3突变体小穗, 分别包含0~3个花药; D1~D2: 野生型和mi-ms-3花粉粒; E1: mi-ms-3 (左)和野生型(右)雌穗表型, mi-ms-3雌穗花丝增多; E2: mi-ms-3 (左)和野生型(右)籽粒表型, mi-ms-3每个籽粒对应多个花丝。

Fig. 1 Phenotypic of the mi-ms-3 and wild type (WT) A: the tassel of WT(wild type) (left) and mi-ms-3 (right), mi-ms-3 anther not exserted; B1-B2: transverse sections of the entire anther of WT and mi-ms-3 in the late microspore developmental stage, mi-ms-3 anthers with only two pollen sacs; C1-C4: the spikelet of mi-ms-3 contain 0-3 anthers respectively; D1-D2: pollen grains of WT and mi-ms-3; E1: the ear of mi-ms-3 (left) and WT (right), the number of silks in the ear of the mi-ms-3 increased; E2: the kernel of mi-ms-3 (left) and WT (right), mi-ms-3 each seed corresponds to multiple silks.
