分裂组织

The ovule of development is the one nucellus that make a group at first organization, because basilar segmentation is rapidder and form or two bags by the layer, bead by , other nucellus the organization laps inside and next alveolus stays in one aspect of the matter, bead aperture .

发育的胚珠最初是一整团珠心组织，由于基部的细胞分裂较快而形成一层或两层包被层—珠被，将其他珠心组织包裹在内并在一端留下一个小孔—珠孔。

IGF2, which encodes a protein functioning as a fetal growth factor and a cell mitogen, is expressed only from paternally allele in most tissues but from both alleles in adult liver. H1 9, which acts as an RNA, is a gene of unknown function and expressed only from maternally allele.

IGF2编码的胰岛素样生长因子-2是一种胚胎生长因子及细胞有丝分裂原，在人体内大多数组织中特异地表达父系来源的等位基因，而母源等位基因处于印记状态。H19表达一种功能尚不清楚的RNA，其印记状态与IGF2相反，目前发现H19在正常组织内均为母源等位基因表达，父源等位基因印记。

During secondary growth,the meristematic PHELLOGEN gives rise to parenchyma tissue,the periderm, which forms the secondary cortex.

在次生生长过程中，周皮分生组织的分裂活动所产生薄壁组织细胞，形成栓内层。

For example, the cytokinins were discovered through work on tobacco pith tissue culture.

细胞分裂素就是在进行烟草髓部组织的组织培养过程中发现的。

More thicker epiphyseal plate were found in the left femurs than the right femurs of the group fixed with plates at 3 and 6 month after operation. In the group fixed with plates, Safranine O staining showed epiphyseal plates ot the left femurs had more fuscous staining than the right femurs at 3 and 6 month after operation. Electron microscopy also found that the cells of the epiphyseal plates of left femurs were more eugenic than the right femurs in the group fixed with plates at 3 and 6 month after operation.

光镜学实验结果示滑动钢板固定的左侧股骨骨骺板总厚度及肥大细胞计数均明显大于普通组；组织化学观察示滑动钢板固定的左侧股骨骺板于术后3个月及6个月Safranine O组织化学染色明显深于普通组；电镜观察示滑动钢板固定的左侧股骨骨骺于术后3个月及6个月软骨增殖区软骨细胞分裂及生长较普通钢板固定的右侧活跃。

Using cytohischemical staining methods, with the results of comparison the dynamics of proteins and polysaccharides in the anthe wall cells and colule cells of different developmental phases in female and male flowers, the anormogenesis of anther tapetum in the inflecting phase of from bisexual flower to unisexual flower was observed. In microspore developed phase, the tapetum functions of preserving and transportingmutritive material for microspore development and of secreting callosal enzyme for decompositing callosal cell lost no normal guadrant formed, of being abnormal meiose of pollen mother cells, and then, the stamen aborted selectively in female flowers and pistil in male flower.

利用细胞组织化学染色技术，对雌、雄花雄蕊花药壁细胞及花药内细胞发育过程中多糖及蛋白质动态进行了比较，实验中观察到雌花在从两性至单性花转变时期雄蕊绒毡层在整个发育过程中表现异常，在小孢子发育过程中未能起到贮藏、转运营养物质供小孢子发育及适时分泌胼胝质酶溶解胼胝质壁的功能，并且花粉母细胞减数分裂异常而未形成四分体结构，进而导致雌花雄蕊选择性败育，而雄花中雌蕊组织也发生了选择性败育过程。

The structure, division and growth of embryogenic callus of litchi and longan were observed by paraffin method.

通过石蜡切片观察荔枝胚性愈伤组织的结构以及分裂、生长的方式，并与龙眼胚性愈伤组织作比较。

Under imitated daily field microclimatic conditions for heat stress, the rice cultivar "Jinyou63"(which is a hybrid rice combination) was treated with a consecutive 3-day heat stress during meiosis in phytotron. Anther and pollen tissues at different development stages after subjected to heat stress were sampled and analyzed for transverse abnormalities.

本研究模拟田间典型灾害天气条件，在人工气候箱内对杂交水稻&金优63&花粉母细胞减数分裂期进行连续3 d的热害胁迫处理，对处理后不同发育时期的花药组织取样切片观察，从组织、细胞水平探讨水稻受高温胁迫后花药可能出现的早期异常特征。

The nucleus of mature egg cell was located at the micropylar end and a great deal of starch grains were in the cytoplasm surrounding the nucleus.

胚囊发育为蓼型，反足细胞分裂形成反足组织，反足组织含有大量淀粉粒，反足细胞直到胚乳细胞化时才退化，反足细胞在胚和胚乳发育中起着积极作用。

When the protoplast-derived calli were transferred into the MS solid medium added with 2.0mg/L benzylamino-purine and 0.4mg/L naphthaleneacetic acid and cultivated in the codition of low illumination, after which the adventitious shoots were induced, then we could obtain numerous plantlets and could transplant them survival to pots in the greenhouse.

当将原生质体分裂形成的愈伤组织转移到附加2.0mg/L6-苄氨基嘌呤和0.4mg/L萘乙酸的MS固体培养基上，并在低光照条件下培养后，从愈伤组织上分化出了不定芽，进而发展成小植株，并移栽成活。

Lugalbanda was a god and shepherd king of Uruk where he was worshipped for over a thousand years.

Lugalbanda 是神和被崇拜了一千年多 Uruk古埃及喜克索王朝国王。
