Two days after HRP injection, the rats were sacrificed and their spinal cords and dorsal root ganglions were sampled for HRP examination.

研究结果：绝大部分被 HRP 所染色的神经元细胞，是在第四腰椎与第五腰椎的背根神经节里被发现到的。

After histochemistry determination, it shows that dioscin take the form of liquid drop and exists mainly in the cells of parenchyma of ground tissue.

经组织化学测定，根状茎中薯蓣皂甙主要存在于基本组织的薄壁细胞中，呈液滴状。

The infection- thread enters and branches in cells of the root cortex.

Herbs, shrubs, rarely lianas, subshrubs, or trees; root, stems, and leaves with oil cells.

草本，灌木，很少藤本植物，亚灌木或乔木；根，茎和叶常有油细胞。

The effect of phosphoric amide herbicide amiprophose-methyl, which was used wildly in agriculture, on chromosome structure and protein composition of root meristems of wheat were studied by exposure to concentrations of 1-4 μmol/L. The results indicated that, as the concentration of APM increased the frequency of chromosomal structure variation increased.

利用农业上广泛使用的酰胺类除草剂甲基胺草磷，在1~4μmol/L浓度下，对野二燕1号小麦根尖分生组织细胞染色体结构变异及蛋白质组分变化进行了研究，结果发现，随着浓度升高，染色体结构变异率呈上升趋势。

Seeds of three genotypes Medicago sative L. were irradiated by 0, 1000, 1500 and 2000Gy 60Co γ-rays, comparison was made among different genotypes at same dosage, and the other is the same genotype at different dosage. The effects of irradiation on root tip cell in Medicago sative L. were studied.

分别利用0、1000、1500和2000Gy 60Co γ射线处理3个品种的紫花苜蓿种子，对同一剂量不同品种或同一品种不同剂量间辐照情况相比较，研究苜蓿根尖细胞的生物学效应。

KEYWORDS: puerarin; pharmacology; retinal pigment epithelial cell; proliferation

目的：葛根素对人视网膜色素上皮细胞增殖及DNA合成的影响。

Low levels of transcripts were also detected in other organs as well as mutant ovules by RT-PCR and Northern hybridization.

进一步的分析表明GhABC1基因在纤维细胞中的表达量很高，在子叶、叶片、茎等组织中低水平表达，在根中则检测不到其转录本。

Somatic embryos can be produced both from the surface and the inner of the calli. Embryogenic cell has normal shape, dense cytoplasm , clear nucleolus, hearty metabolize; Plantlet regenerations were developed from global embryo, heart-shaped embryo, torpedo-shaped embryo and cotyledon embryo, in which the V-shaped vessel vascular bundles and shoot tip meristem and root tip meristem were observed.

胚性细胞多为椭圆形，细胞质浓厚，核仁明显，代谢旺盛；体细胞胚经过球形胚、心形胚、鱼雷形胚和子叶胚而发育成再生植株，子叶期体细胞胚可观察到明显的V型维管束、茎尖分生组织以及根尖分生组织。

Comparison of different types of stem cutting in rooting induced and analysis the cDNA clones which may be associated with the occurrence of adventitious roots of P.euphratica,the model of ARF were initial establishment of exogenous IBA controlling endogenous IAA occurred threshold and equilibrium,that is,exogenous IBA receiving by receptor of stem cutting,and transfer into the cells,then turn into active IAA by the effects of the POD enzyme.

通过对胡杨3个不定根发生调控培养体系的比较和与胡杨不定根发生可能相关的差异基因的克隆分析，初步建立IBA调控胡杨不定根发生的内源IAA阈值和激素间平衡的模型，即外源IBA通过插穗受体接收，转入细胞内并在POD酶作用下转化成具有活性的IAA，当IAA的水甲在促根的阈值内并保持相对平稳时，则有利于生根；当IAA的浓度增高超过阈值且不稳定时，则抑制不定根的发生。

Fancy gold-plated dangling earrings with facetted White Opal crystals.

花式镀金悬垂耳环与facetted白欧泊水晶。

This essay chooses the study aim from biology teachers in middle school in Shi Jiazhuang which tells us that most of the middle school biology teachers in Shi Jiazhuang have the"burnout", lower successfulness, individualize.

本文选取石家庄市初中生物教师作为研究对象，运用问卷调查的方法对石家庄市初中生物教师职业倦怠的现状进行调查，调查结果发现，石家庄市初中生物教师这一群体普遍存在职业倦怠，情感枯竭程度偏高，成就感偏低，去个性化程度最为严重。
