查询词典 female gametophyte

Epiphytic bacteria were isolated from sporophytic thallus collected from Qingdao and Dalian or gametophytic filaments stored in our lab of Laminaria japonica. Identification was done using both traditional physiological and biochemical way and molecular method. Phylogeny tree was established based on 16S rRNA gene sequence analyses, and some sequences of epiphytic strains from both sporophyte and gametophyte were different from all the sequences already exit and could be the new species.

采用生理生化和16S rRNA基因序列比对的方法对从两个海区采集的海带孢子体以及实验室中保存的海带配子体样品的外生菌分别进行组成分析，16S rRNA基因序列揭示了在海带孢子体和配子体的外生菌中都存在一些与现有数据库中序列的遗传关系较远的菌株。

In order to trace the male cytoplasm transmission during double fertilization process, the mature gametophyte, zygote, proembryo and primary endosperm in Pelargonium hortorum Bailey and Rhododendron mucronulatum Turcz were investigated using transmission electron microscope and DNA staining technique.

本研究应用透射电镜及DNA荧光技术对天竺葵和杜鹃的成熟配子体以及在受精以后雄性细胞器的存在和分布进行了系统的细胞学研究，阐明了这两种植物中雌性生殖单位的超微结构特点及雄性和雌性细胞中质体和线粒体在受精作用中的传递。

Polysomes change in number as "few-many-few-many" during the development of the egg, early zygote stage, zygote at dormancy, zygote in prophase of mitosis and two-celled proembryo in sugar beet, which indicates that such changes in metabolism as "low-high-low-high" activity may relate to the transformation from gametophyte to sporophyte generation.

根据上述结果可以得出，栽培甜菜从卵细胞成熟→合子初期→合子休眠期→合子分裂前期→二细胞原胚的超微结构变化中多聚核糖体的变化最为显著，表现为&少→多→少→多&的数量变化过程，反映出细胞代谢状态也经历了&弱→强→弱→强&的变化过程，这种变化趋势与配子体世代向孢子体世代转变有关。

Light microscope was employed to observe spore germination, protonemal development, gametophyte differentiation of Ptychomitrium sinense indoor cultured. The results showed that in P.

：通过室内人工培养中华缩叶藓的孢子，在光学显微镜下详细观察了其孢子萌发、原丝体发育及配子体发生的全过程。

About a year after pollination, the generative cell of the four-celled male gametophyte undergoes division, giving rise to two kinds of cells—a sterile cell and a spermatogenous cell.

在授粉后大约一年，四个中生殖细胞-细胞男性的配偶体接受区分，引起细胞的二个类型-一个不毛的细胞和一个 spermatogenous 细胞。

The temperature affects the sustained time of secondary sporogenous cell split, the sustained time of microspore mother cell, formation speed and regular of male gametophyte.

温度影响次生造孢细胞持续分裂的时间、小孢子母细胞的持续时间及雄配子体的形成速度和整齐度。

The first split of microspore mother cell is observed after one week after beginning of temperature arised under high temperature but the split of secondary sporogenous cell doesn't be found. The split of secondary sporogenous cell is still found after one week but the first split of microspore mother cell is observed after 12d under low temperature. Formating speed of male gametophyte is affected by temperature.

在高温条件下，开始加温1周后即看到小孢子母细胞进行第一次分裂，未观察到次生造孢细胞的分裂；在低温条件下，1周后仍能看到次生造孢细胞的分裂，12d后才看到小孢子母细胞进行第一次分裂。

In conclusion, high genetic identities were found in sporophytic offspring derived from mono-crossing of gametophyte clones of U. pinnatifida by means of both AFLP and microsatellite markers, however, subtle genetic variations were also detected.

总之，AFLP与微卫星的分析结果一致，即配子体克隆单一交配组合的孢子体后代呈现高度遗传相似性，但也存在细微的差异。

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。

Hornworts; liverworts having a thalloid gametophyte; in some classification systems included in the class Hepaticopsida.

金鱼藻；有叶状配偶体的地钱；在有些分类中，被归于苔纲中。

The use of the web to spread fears that flicking the switch on the LHC could create a Black Hole that could swallow up the Earth particularly concerned him, he said.

他说，使用互联网散布恐慌说启动LHC会生成一个可能吞噬地球的黑洞的做法让他感到忧虑。
