孢子的细胞

In angiosperms, a diploid embryo may develop from a cell of the nucellus or chalaza; this is also apospory.

在被子植物中。二倍体的胚胎可以从珠心或合点的细胞发育而来，这也可以被称为无孢子生殖。

As a result penicillium of Ma Erni humble is double photograph bacterium, mould bacterium colony can discover the broom shape mycelial of diagnostic sex,; of pigment of rose of water-solubility of the generation after sanded Paul fosters 3 days is medullary inside and outside of cell of blood of the week outside mixing all can discover spore;PAS coloring sees bacterium body show circle, elliptic or sausage shape, size is differ, it is 2~8 μ M about, color of afterbirth wall incarnadine and clear and successive, it is thus clear that inside the cell of sausage shape one apparent horizontal stroke is lain between, afterbirth is qualitative not easy and chromatic.

结果马尔尼菲青霉菌为双相菌，霉菌型菌落可发现特征性的扫帚状菌丝，沙保罗培养3天后产生水溶性玫瑰色素；骨髓和外周血细胞内外均可发现孢子；PAS染色可见菌体呈圆形、椭圆形或腊肠状，大小不一，约为2~8μm，胞壁染红色且清楚连续，在腊肠状的细胞内可见一明显的横隔，胞质不易着色。

Observation was made on the cell morphology of the microspore development of the sterile and fertile plants in the Aibai wheat.

对矮败小麦中的可育株和不育株进行了小孢子发育过程的细胞形态学观察。

Another form of apomixes in which seeds develop from unfertilized gametes can also be termed parthenogenesis.

以这种方式产生的种子不是单倍体就是二倍体，完全取决于大孢子母细胞是否经历减数分裂。

Hyphae and swollen cells resembling chlamydospores were observed in the scrapings of skin lesion of the experimental infection of the rabbit.

在实验家兔的皮损刮屑中可见菌丝及类似厚壁孢子的肿胀细胞。

Past study re-sults had indicated that MMC in the apomictic type could at most develop to te-trad stage.We observed that the sexual embryo sac of"Pingyi Tiancha"coulddevelop into 4-nuclei embry sac.

前人只观察到无融合生殖类型的大孢子母细胞至多能发育到四分体时期，而我们观察到平邑甜茶的有性胚囊能发育到四核胚囊。

2N gametes are the result of meiotic mutation during micro- and mega-sporogenesis that bear the sporophytic rather than the gametophytic chromosome number. This paper reviewed the genetic markers including the morphologic, cytological, isozymes and DNA markers, which have been employed in the generation, inheritance, heterozygosity and marker-assisted breeding of 2n gametes based on the frequency of large pollen grains, cytological analyses, unexpected occurrence of polyploidy progeny and the associations between parents and progenies.

文章综述了植物2n配子发生及其遗传标记研究现状，论述涉及有关形态学标记、细胞学标记、同工酶标记乃至DNA标记等遗传标记在2n配子研究中的应用，指出通过花粉形态观察、大小孢子母细胞减数分裂行为观察、杂种后代倍性鉴定以及亲子分子标记相关分析等，对2n配子发生、2n配子遗传类型与杂合性以及2n配子在育种实践中的有效性等进行研究。

Microsporidia are ubiquitous intracellular parasitic protozoa infecting all types of animals.

微孢子虫是广泛分布於自然界的细胞内原虫类寄生物。

These abnormal changes mainly occurred at two stages:(1) at meiotic prophase, almost half of Peiai 64S microsporocytes exhibited aberration, with sparse free ribosomes, underdeveloped mitochondria and many swollen endoplasmic reticula.

这些变化主要发生在两个阶段：（1）减数分裂前期，约半数的小孢子母细胞的胞质出现异常，游离核糖体稀少，并具有不发育线粒体和大量泡状内质网。

These abnormal cells became dramatically vacuolated and hereafter disintegrated completely at later stage.

这类异常的小孢子母细胞在随后的发育中逐渐液泡化并最终解体。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
