查询词典 mother cells

Since microspore mother cells showabortion during the first meiotic divison,it is suggested thatthe early male abortion is frequently associated with variousdegrees of impairment to the fertility to the female〓amate.

研究的27个杂种第一代中，有11个组合的产量超过对照或与对照持平，占总组合数的40.74%。在强优势组合中，不育细胞质带来的负效应不足以使F1产量的显著降低，而且通过杂优补偿作用可比对照有所提高。

Staining with the improved carbol fuchsin-aniline blue fluorescence method is a convenient and efficient way to observe the behavior of the callose wall of microspore mother cells during meiosis.

利用改良苯酚品红－苯胺蓝压片法，观察小孢子母细胞减数分裂过程中胼胝质的动态变化。

There are nine bivalents in pollen mother cells at late diplotene or early diakinesis, and the homologous chromosomes essentially arrange on the equatorial plate at late metaphase Ⅰor early anaphase Ⅰ, then the two homologous chromosomes of each bivalent separate from each other and move to two opposite poles drawn by spindle fibers.

在减数分裂双线期末或终变期初，可以观察到9个二价体，在中期I末至后期I初，同源染色体基本排列在赤道板上，然后在纺锤丝的牵引下二价体的两条同源染色体分开，分别移向两极，每一极有9条染色体，从而确认该属植物的染色体基数为x=9。

Barley seeds were irradiated with five different doses of 60 Co-γ ray.There were many kinds of chromosome aberration in pollen mother cells,such as bridge,laggards in anaphase I and anaphase II,asymmetrical division in anaphase I and asynchronous division in anaphase II,ring quadrivalent in metaphase I,three pole division and micro-nuclei in telophase I,micro-nuclei in tetrad and some micro-nucleus separates from the tetrad to form polyad.

大麦种子经5种不同剂量γ射线辐照后， M1植株的花粉母细胞出现多种染色体畸变类型，例如后Ⅰ、后Ⅱ中出现桥、落后，后Ⅰ中出现不对称分裂，后Ⅱ中出现不同步分裂，中期Ⅰ出现环状四价体，末期Ⅰ中有三极分裂和微核，四分体中出现微核且有的微核独立于四分体，从而形成多分体。

The dominant male sterility was expressed normally in the new Taigu genic sterile wheat carrying the intergenomically translocated Ms2, and the female fertility mechanism in its male sterile plants was normal as well. Observation of the chromosome configuration at meiosis of pollen mother cells of the young ears of the sterile plants showed that they were euploid plants (2n=42). No configurations different from those of the Taigu geneic sterility gene located at the original locus were noticed of the Ms2 intergenomically translocated back into the common wheat.

所获携带易组Ms2基因的新型太谷核不育小麦其显性雄性不育特性表达正常，且雄性不育株的雌性可育机制正常，对不育株幼穗花粉母细胞减数分裂期染色体构型的观察可见其为整倍体(2n=42)，尚未发现回归普通小麦的易组太谷核不育基因与原位点的太谷核不育基因有不同的表型。

2The mother cells of macrospore and microspore directly go mitosis by-passed meiosis to form normally fertility gametes.

分析其主要原因在于：①雌配子不育；②雄配子不育；③雌雄配子之间的亲和性障碍；④雌雄配子发育不同步；⑤单受精。

When skin is young, the natural repair functions in the germinative layer's mother cells perfectly counterbalance their deterioration, allowing them to reproduce as new, intact, identical daughter cells.

年轻时，肌肤真皮层内的母细胞拥有天然的修护机能，完美平衡皮肤细胞的退化，复制出完美健康的子细胞。

Like a faulty photocopier, the reproduction of mother cells into daughter cells ineluctably deteriorates.

就像复印机出现故障，从母细胞到子细胞的复制进程发生无可避免的错误。

After the aggregates have formed the sporogenous cells inside the- aggregates(which could now be called massulae)divide to form numerous pollen mother cells.

在文献中有关兰花花粉块的成熟结构的描述已有很多一刃，但有关兰花花粉块的形成过程的报道

The haploid pollen cells develop in the tapetal zone from spore mother cells.

单倍体花粉细胞由绒毡层提供营养发育。

Methods: Five patients with parkinsonism or dystonia were assigned to general anesthesia using an modified endotracheal tube.

本实验依照人体实验之相关规定进行，五位患有帕金森氏症或肌张力异常的病人接受神经立体定位手术。
