The results suggest that exterior of nomal PAM has plenty of microruga, the surface area of PAM was increased so as to make it possible to conglutinate and englut more conidia when activated by Aspergillus fumigatus conidia; at the same time, it provides the histologic evidence of augmentation of lysosome and endoplasmic reticulum.

我们发现，正常PAM 表面有大量微皱褶或微皱襞，在被烟曲霉孢子激活后，PAM 可以明显增大细胞的表面积，即可以使一个巨噬细胞同时粘附和吞噬多个

Cinnamaldehyde and citral have directly or indirectly interfered the conventional synthesis of fungal hereditary DNA and RNA and normal differentiation of conidiophore in A. flavus and A. fumigatus, thus inhibiting the normal cell cycle and the growth and propagation of fungi.

肉桂醛、柠檬醛直接或间接影响了真菌细胞遗传物质的正常合成，以至不能完成正常细胞周期，影响分生孢子梗的正常分化，从而抑制真菌生长、繁殖。

The Cork was consisted of five or six layer long cells. The secondary phloem occupied 46% of the diameter of root, and the parenchymas cell was abundant of the inclusions. The secondary xylem consisted of vessel, xylary radial ,and a little of xylary parenchyma cells. Some segment of hypha, swelled hypha, pelotons and conidiophore were colonied in cork and secondary phloem.

周皮由木栓层，木栓形成层和栓内层组成，其中木栓层由5～6 列长形细胞组成；维管组织中次生韧皮部所占根径的比例达46%，其薄壁细胞中内含物较丰富，次生木质部中分布有导管和木射线及少量木薄壁组织；在格木木栓层和次生韧皮部中分布有菌丝片段、膨大的菌丝和菌丝团及分生孢子。

In the gymnosperms the megaspore gives rise to a cell that is termed the embryo sac because of its similarity to the angiosperm structure.

在裸子植物中，大孢子也产生一个细胞，因为它类似于被子植物的胚囊细胞，故也可以称之为胚囊。

Based on principle of pollen abortion, utilizing tapetum of anther cell, mitochondria of tapetum, callose well, process of cell meiosis during formation process of pollen, we adopt genetic transformation to create plant male sterility, such as, exogenous cytotoxin gene, chaperones, anti-sense RNA, degradation of callose ahead of time, disturbing information intercommunion between mitochondria and nucleolus and affected development of pollen sporule by bacteria.

根据花粉败育的原理，利用花药细胞绒毡层、绒毡层线粒体、胼胝质壁、细胞减数分裂过程等花粉形成过程中的不同环节，采取外源细胞毒素基因、分子伴侣、反义RNA技术、提早降解胼胝质、扰乱线粒体与细胞核之间的信息交流和细菌影响花粉小孢子发育等策略，使花粉不能正常形成，从而产生不育花粉，达到产生雄性不育的目的。

In succession, the middle layer of anther wall had the strongest Ca^2＋ fluorescence intensity, and the tapetum took second place during the meiosis of microspore mother cell.

小孢子内Ca^2＋分布不均匀，细胞质中的Ca^2＋荧光较弱，细胞壁处Ca^2＋荧光较强，二细胞花粉时期，细胞呈现较强的Ca^2＋荧光。

The analysis shows that under heat stress, meiocytes degenerate while tetrad cell dispersion fails at microspore formation phase. During pollen maturation phase, loss of orientation of reproductive cells, abnormal vacuolization of tapetal cells, paramorphia or abortion of anther walls and pollens are observed under heat stress.

结果表明，受高温胁迫后，在小孢子形成阶段，水稻花粉母细胞发育异常、四分体无法适时分散；在花粉粒成熟阶段，水稻生殖细胞失去正确的排列方向、绒毡层细胞发生非正常分解、花药壁和花粉粒发生形态异常并出现败育。

Objective whether ganoderma spores can promote the neural epithelia of embryonic neural tube stagnated by retinoic acid in G0/G1 phase reentering into the cell cycle, and keep proliferation and differentiation, which can reduce the occurrence of neural tube defects.

目的 探讨灵芝孢子能否促进受维甲酸诱导停滞在G0/G1期的胚胎神经管神经上皮细胞重新进入细胞周期循环，继续增殖和分化，减少神经管畸形的发生。

It"s vegetal mycelia were colorless, smooth, 1.2μm～3.0μm crude, manyconidiogenous cells born on vegetal mycelia, sometimes as many as a dozen,a very small number were single. The base of conidiogenous cell wasenlarged and many of them were bottle-shaped or spherical. The upper ofconidiogenous cell extended into a conidiogenous axis of 1μm wide and 14μm length which was the knee-bending ("Z like bending), there were small pectinae on the axis, conidium located on the small pectina.

营养菌丝无色，光滑，有隔，粗1.0μm～3.0μm，产孢细胞常浓密簇生于菌丝或泡囊上，有时可多达十几个，极少数单生，产孢细胞基部膨大，多为瓶形，近球形，颈部明显延长成粗1μm，最长达14μm的产孢轴，呈膝状弯曲，轴上具小齿突，分生孢子位于小齿突上。

Endospores are formed within the cell, one in each parent cell, and are surrounded by a thick coat containing dipicolinic acid.

内生孢子是在细菌细胞内形成的，且每一个母细胞只形成一个，形成后被含有2，6吡啶二羧酸的厚壁所包围。

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