- Some large vacuoles appeared in the tapetal cells of the sterile anthers at the early uninucleate pollen stage. 在单核细胞早期,不育花粉的四分体细胞中有较明显的大液泡出现。
- In contrast,tapetal cells of fertile anthers began to degenerate at the stage of mononuclear pollen. 可育株绒毡层在单核花粉粒期开始解体,花粉粒成熟期时完全解体。
- The abnormity of tapetal cells vas also an important reason for the degeneration. 另外,绒毡层细胞质的液泡化也是小孢子败育的一个重要原因。
- The pollen sterility of 392A, 86A and 629A are closely related with the abnormal growth of tapetal cells. 392A、86A和629A的花药败育与绒毡层发育异常有密切的关系。
- The abnormity of tapetal cells was also an important reason for the degeneration. 另外,绒毡层细胞质的液泡化也是小孢子败育的一个重要原因。
- During the anther development, the tapetal cells or digesting tapetal cells kept at high level of ABA. 绒毡层或降解中的绒毡层细胞内有较多金颗粒分布。
- When microspore mother cell (MMC) preparing meiosis, calcium precipitates appeared in the cytoplasm of tapetal cells and callus wall surrounding MMC. 当花粉母细胞进行减数分裂时,花药中的钙颗粒进一步增加,尤其是在小孢子母细胞的胼胝质壁中。
- Tapetum cells were elongated, vacuolated or tapetum was made up of multilayer cells or discomposed tardily. 绒毡层细胞径向过度伸长,高度液泡化,且出现多层细胞,严重挤压小孢子母细胞,解体较晚且充塞花粉囊室;
- The middle layer and the tapetum cells are totally absorbed as nutrient at last. 中层和绒毡层细胞最终作为营养被全部吸收利用。
- Meanwhile, it was presumed that the tapetal cells in male sterile anther underwent premature programmed cell death (PCD) based on the DNA ladder. 利用DNA梯度技术发现不育系绒毡层细胞提早发生程序性死亡。
- At the stage of microspore, the tapetal cells evidently degenerated, and starches in parenchyma around vascular bundle became large. 在小孢子时期,药隔薄壁细胞中淀粉粒体积增大,绒毡层细胞明显退化;
- Tapetal cells go through many cycles with respect to dilation of rER, few or many vesicles and production of Ubisch bodies. 在小孢子的液胞期一开始,营养层细胞即行有丝分裂。在小孢子的液胞期的全盛时期。
- At the late microspore stage, the degeneration of the tapetal cell begins, and the thickening of the endothecium cell wall by callose happens. 小孢子晚期,绒毡层细胞开始解体,药室内壁细胞开始加厚,其加厚的物质为胼胝质类物质。
- At late anther developing stage, the tapetal cells became to vacuolated, anther chamber was full of giant tapetum and the microspore degenerated completely. 而绒毡层细胞的异常从花粉母细胞时期一直持续到二分体直至四分体。
- Abbreviation: T: Tapetal; N: Nucleus; TE:Tetrad; TW: Wall of tapetal cell; V: V acuole; D: Dictyosome; C: Callose; M: Mitochondria. 绒毡层细胞,N:细胞核,TE:四分体,TW:绒毡层细胞壁,V:液胞,D:高尔基体,C:胼胝质壁,M:线粒体。
- During meiotic cell division stage, wall of tapetal cells dissociates and disappears, plasmodesmata break down, asynchronous condition occurs in cell development. 减数分裂期,绒毡层细胞壁融解消失,胞间连丝断离,细胞间发育出现不同步现象。
- Anther wall was formed in a special method due to the homology of tapetum cell and secondary sporogenous cell. 花药壁按特有方式发生,主要特点是绒毡层与次生造孢细胞同源。
