Fusiform initial's and morphology and division.

纺锤状原始细胞的形状和分裂

During conjugation, the complementary mating type cells unite pairwise undergo meiosis, exchange gametic nuclei and separate again.

在接合生殖期间，交配型互补的细胞相互识别配对，进行减数分裂、交换配子核，然后分开。

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。

Fromthese facts,It could be deduced that 8 to 14 pairs of chromosomes possessed a certaindegree of hetorology,which was directly groved to be hybrid origin of P.tomentosaaccording to the good chromosome homology and fertility of P.bolleana and thehybrids of P.tomentosa×P.bolleana,it could be further deduced that the original parentsof P.tomentosa involved probably P.bolleana or P.alba.

从终变期、中期I的染色体构型看，有数目不等的联会程度较差的单价体和棒状二价体出现，在后期I，甚至末期I亦可见到含落后染色体分裂相的细胞，由此推断可能有8~14对染色体表现出一定程度的异源性，鉴于新疆杨以及毛白杨与新疆杨杂交产生的杂种毛新杨的染色体同源性较强、育性较好等现象，进一步推断毛白杨起源亲本可能包括新疆杨或银白杨。

Analysis of double mutants between bro-1(bp133) and several heterochronic mutants showed that the proliferative seam cell division occurred at any stage was defective in bro-1 mutation background.

对bro-1和不同异时基因构成的双突变的细胞谱系分析表明在L2时期以外时期出现的增殖性分裂也可以因为bro-1基因的突变而缺失。

Methods A retrospective analysis was done in 11 cases of AM in terms of their clinical data and histological characteristics, such as cell caryomitosis, cell heterotype and tumor necrosis. The survival and recurrence were followed up.

回顾性分析11例AM病人的临床资料与光镜下的组织学特征，计数核分裂象、细胞异型程度以及肿瘤坏死的情况，并随访病人的生存情况和复发率。

Significant correlation was found between TrfR expression and histologic tumor type, grade of a...

提示TrfR的表达与肿瘤细胞的分裂增殖和侵袭力有关，具有一定的潜在预后价值。

Interfascicular cambium A single layer of actively dividing cells between the vascular bundles in stems.

束间形成层：束间形成层是位于茎的维管束间的具有旺盛分裂能力的一层细胞。

Intrafascicular CAMBIUM between xylem and phloem. Apical initials are rarely single cells except in certain lower plants, and initiate more than one structure, e.g.

这种细胞存在于根和芽的顶端分生组织以及在原来分裂组织基础上形成的侧生分生组织，如位于木质部和韧皮部之间的束中形成层。

Pinl is a unique peptidyl-prolyl cis/trans isomerases and can specifically isomerize the phosphorylated Ser/Thr-Pro bonds in certain proteins, thereby modulating their functions.

肤基脯氨酞顺反异构酶Pinl，是由酵母双杂交筛选出的一种功能蛋白，主要调节有丝分裂相关蛋白酶，对细胞周期运行起着非常重要的调节作用赶'〕。

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