配子体的

C The mature male gametophyte consists of three cells resulting from two meiotic divisions.

成熟的雄配子体包括的三个细胞是由两次减数分裂而来的

The female gametophyte of flowering plants may have evolved through iteration of a modular structure and a gradient of the hormone auxin.

开花植物的雌性配子体可以通过模块结构的迭代和生长激素的梯度进行演化。

Then took calli of Physcomitrella patens on the media plus different plant hormones, normal gametophyte of Physcomitrella patens were differentiated in medium Knop.

诱导愈伤组织分化的实验结果表明：未添加任何植物激素的Knop培养基上分化出正常的配子体且数量最多。

Rhizoid A unicellular rootlike structure found in certain algae and in the gametophyte generation of the bryophytes and some ferns.

假根：在一些藻类、苔藓植物和裸子植物配子体中存在的由单个细胞形成的类似根的结构。

Although gametophytic self-incompatibility functions can ultimately prevent self-fertilization , flowering plants have adopted different signal transduction pathways to reject self pollen .

配子体SI植物虽然都具有其SI的功能而阻止自我受精，但它们采取的信号转导途径是不同的。

There formed segregating cavities between spermatocyte cell-wall and spermogonium cell-wall and osmiophillic layers outside spermatocyte cytoplasmalemma, which indicated that the spermatocytes had begun to gradually break away from the male gametophytes and embark on independent development.

精母细胞与精子器的璧细胞之间形成了分离腔，在精母细胞质膜外形成了嗜锇层，这些结构的形成说明精母细胞已经开始与雄配子体逐渐分离，进入独立发育的阶段。

The aberrant phenotypes were observed in the anther of tobaccotransformed with ZM401 sense construct: the inflorescence growth and floral axiselongation are suppressed; the flower buds falling or flowers abscission earlier wereobserved. The degradation of tapetum are not observed at the binucleate pollen stagewhich corresponds to the mature stage, although the tapetal cells of untransformedtobacco anther at the same stage have already degenerated completely anddisappeared.

对转基因烟草进行形态学、组织学分析结果表明，ZM401基因以反向方式整合的转基因烟草表现一切正常，而含有ZM401正义基因的转基因烟草在表型和组织学上都出现了异常：花序生长缓慢，花序轴变短，生长过程中花逐渐脱落，花序轴褐化枯死；花药绒毡层退化延迟，药室内壁在雄配子体发育后期不能进行带状加厚，阻碍了花粉粒的释放。

For the approach to the relations between the endangered situation and their sexual reproductive processes in Cimicifuga nanchuanensis, some comparative studies were made in C.simplex , a close and widespread species.

为了探讨南川升麻濒危与其生殖过程的联系。对广布近缘种单穗升麻进行了部分对照研究。论述单穗升麻的小孢子发生和雄配子体发育以及花药壁的发育。

In the Coniferophyta the female gametophyte is reduced to a nonphotosynthetic tissue with up to 2000 nuclei in the ovule, which produces archegonia.

松柏类植物的雌配子体成为颈卵器，其胚珠为含有2000个以上的核的非光合组织，（参见 archegonium ）。

The proportion of megaspores to forming sporelings was only about 12%. Frequently no more than 1% of the sporelings grow up to become mature individuals.

在已萌发的雌配子体中，幼苗的形成率仅为12%，模拟中华水韭野外生长的条件下移栽幼苗，其成活率非常低，不足1%。

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。
