配子体

First, we determined the chromosomal location of the S locus in Antirrhinum by fluorescence in situ hybridization of metaphase chromosomes of a self-incompatible line of S〓S〓 using an S〓 RNase gene and its corresponding 63kb BAC clone as probes, respectively.

玄参科植物金鱼草的自交不亲和性和茄科和蔷薇科类似，都属配子体自交不亲和植物，它们S位点都编码一类控制花柱自交不亲和性的核酸酶，称为S RNase。

The result of ISH indicate that the FIE gene has specialspatio-temporal expression in apomixis E.binata during the reproduction growth andcontrols the development of embryo and endosperm.

原位杂交的结果表明FIE在龙须草生殖发育的过程中特异的时空表达，与雌雄配子体发育有关，并参与调节胚和胚乳的发育。

One of two sperm get into an archegonium and fused with egg. The nucleus of fertilized egg began to divide, and the walls were formed after the third division. The eggs without fertilization divided two times and then disappeared.

雄配子体产生的两个精子中的一个进入颈卵器与卵细胞结合形成受精卵，受精卵核到第3次分裂形成细胞壁，没有受精的卵细胞还要进行两次有丝分裂后才消失。

In this paper the authors reviewed the characteristics in the different phases in the life cycle of ferns. Special attentions were given to the effect of light, plant growth regulators, water and temperature on the fern gametophyte development, and the effect of antheridiogen, light, calcium and other plant growth regulator on the formation and differentiation of fern sex organ.

作者概述了蕨类植物生活周期中不同发育阶段的特点，并着重介绍了光、植物生长调节物质、水和温度等因素对蕨类植物配子体发育的影响以及成精子囊素、光、钙离子和其它植物生长调节物质在性器官形成和分化过程中的作用。

Cytogamy The fusion of gametes during fertilization.

细胞融合：通过受精作用达到的配子体的融合。

As the male gametophyte, pollen delivers sperm to the embryo sac for fertilization by pollen-tube polarized growth.

花粉作为种子植物的雄配子体，通过萌发后极性生长的花粉管将精细胞送到胚囊完成受精作用。

AFLP and microsatellite markers were adopted to assess the genetic identity of the sporophytic offspring derived from mono-crossing of gametophyte clones of Undaria pinnatifida.

用AFLP和微卫星标记对裙带菜配子体克隆单一交配组合的孢子体后代的遗传一致性进行分析。

Moreover, the extremely slow development of gametophyte and time interval between the appearance of antheridia and archegonia resulting from the inherent physiochemical property of red soil make it impossible to fertilize and generate sporophyte.

此外，红壤固有的理化性质导致扇蕨配子体发育极其缓慢、精子器和颈卵器发生的时间间隔过长使其不能受精产生于包子体。

The green, filamentous growth that arises from spore germination in liverworts and mosses and eventually gives rise to a mature gametophyte.

原丝体由叶苔或苔藓的孢子萌芽发展而成的绿色丝状生长物，最终发展成配子体

The green,filamentous growth that arises from spore germination in liverworts and moss es and eventually gives rise to a mature gametophyte.

原丝体由叶苔或苔藓的孢子萌芽发展而成的绿色丝状生长物，最终发展成配子体

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。
