胼胝质

It was found that callose appears in microsporangium at the microspore mother cell formation stage.

结果发现，胼胝质最早于小孢子母细胞形成期出现于花粉囊中。

Hypersensitive reaction and callose formation were two important resistance mechanisms.

过敏性坏死反应和胼胝质的形成是2个重要的抗锈机制。

The pores are lined with callose, and allow cytoplasmic strands to pass from one sieve cell to the next.

孔与孔之间列成直线由胼胝质联系，其内允许细胞质细流从一个筛胞通向另一个。

Callose An insoluble polysaccaride that is laid down around the perforations in sieve plates, at wound or infection sites, and by growing pollen tubes.

callose 胼胝质：在植物筛管的筛域上存在的一种由不溶性的多糖物质积聚而形成的结构。

Callose stains are aniline blue, resorcin blue and rosolic acid.

胼胝质的染剂是苯胺蓝，间苯二酚蓝和玫红酸。

The abnormality of tetrad callose wall degradation and tapetum development was associated with the abortion of microspore.

导致小孢子败育的原因与四分体胼胝质壁不适时解体和绒毡层细胞发育异常、延迟解体有关。

This paper briefly describes the progress in cytoplasm reorganization, dynamics of wall callose, starch granules and organelles in pollen grains, the tapetum development, specific genes, asymmetric division and cell fate determination in developing pollens. Some problems and future research directions are pointed out in this review.

本文针对花粉发育过程中的细胞质改组；胼胝质壁、淀粉粒和细胞器的动态变化；绒毡层的发育；花粉发育特异基因；以及不对称分裂和细胞命运等几个生物学问题的研究进展作了简要综述，最后还提出了一些研究展望。

In early stage of tetrad,primexine produces between the plasmolemma and calloses.

四分体初期，在质膜与胼胝质之间产生原外壁，然后，在原外壁中产生原棒，进而形成了基粒棒。

In the stage of sporogenous tissue, the Ca^2＋ fluorescence intensity was well-proportioned in different cell layer of anther wall.

早期四分体小孢子细胞质中Ca^2＋荧光强度较强，胼胝质壁无荧光；后期细胞质中的Ca^2＋荧光减弱，而胼胝质壁处Ca^2＋荧光增强。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
