分生孢子发育的超微结构研究表明，分生孢子壁的发育是有个由薄而光滑到厚而有疣的过程；期间脂肪体在分生孢子和产孢细胞中不断累积，最后脂肪体沿着内壁排列成一层。

The megaspore mother cell is located at the 3rd or 4th layer of cells in the nucellus top end. It divides transversally to form a linear megaspore tetrad, and the megaspore at the chalazal end develops into the embryo sac mother cell.

大孢子母细胞位在珠心顶表皮下第三或四层细胞处，经横分裂后产生一直线形的大孢子四分体，其中位居合点端的大孢子发育成胚囊母细胞。

Could be observed on 10th day after pollination, archesporial cell on 20thday, megasporocyte on 24th day, the functional megaspore on 30th day; and 8-nucleate embryo sac on 41th day. And then double fertilization finish and early globular embryo emerg.

授粉10 d出现指状突起，20 d形成胚珠原基，24 d大孢子母细胞发生，30 d功能大孢子形成，41 d发育为成熟的八核胚囊，而后完成双受精发育成早期球形胚。

Young thalluscells of low development are easy to dedifferentiate and grow intoseedings directly,while mature thallus cells have to releasemonospores to form seedings through a stage of multicellular groupfor dedifferentiation.Old thallus,mainly of productive cells,releasecarporspores to form conchocelis at last.

幼嫩的叶状体细胞，由于其分化程度低，易于脱分化而直接长成细胞苗；成熟的叶状体细胞，要经过多细胞团这样一个脱分化的阶段，然后放散单孢子成苗；而老叶状体以生殖细胞为主，只能放散果孢子，最终长成丝状体。

It was proved that low concentration Fe2+ can acce lerate its growth and development,but high Fe2+may lead to seedlings defor mity, make the cells become small and the seedlings divide into monospores again and again.

结果表明，低浓度的 Fe2+能促进其生长发育；而高浓度的Fe2+可以导致苗大量畸变，细胞变小，苗反复崩解成单孢子。

The characteristic in liquid culture of the purified strains were described, and the relation between the characteristic and the taxonomic traits was researched for the first time. The two groups of Myxobacteria differentiated according to the shape character of the myxospores and vegetative cells had different characteristic in liquid culture.

对纯化菌株的液体培养特征进行了描述，并首次依据初步分类鉴定结果探索了液体特征与分类地位之间的关系，即依据营养细胞和粘孢子形态将粘细菌划分成的两大类型中，第一类型(包括粘球菌属等7个属)的菌株在液体培养基中通常形成片状或絮状，而第二类型(包括单囊菌属等5个属)的菌株则主要呈现球形。

Under favorable condition, it multiplies as a unicellular organism. Upon starvation, a pathway involving aggregation, mound, slug, culmination stages induces the formation of a fruiting body consisting of a head of spores supported on a stalk of vacuolated cells.

在营养丰富条件下，以单细胞形式存在；一旦食物匮乏，单个细胞聚集成多细胞体，细胞历经细胞丘、蛞蝓体、拔顶阶段完成发育和分化过程，最终形成由孢子细胞和柄细胞组成的子实体。

Hours after inoculation, penetration of the fungus and formation of haustoria in transformed cells were observed to evaluate the effects of the target gene's products on the invasion of powdery mildew.

转化后接种白粉菌孢子，48 h后观察转化阳性表皮细胞，研究抗病相关基因表达对白粉菌入侵及吸器形成产生的影响。

Sp. tritici conidiospores. 40 h after inoculation, penetration of the fungus and formation of haustoria in transformed cells were observed to evaluate the effect of the target gene's product on the invasion of the fungus.

基因枪轰击后高密度接种白粉病菌孢子。40h后观察转化阳性表皮细胞度其表面抱子的发育，并以阳性转化细胞中白粉病菌成功侵入的细胞所占比例为指标分析目标基因的表达对白粉病菌入侵及吸器形成产生的影响(对照为单独导入GUS基因的表皮细胞)。

Screened with cOnidia of hauIthe mp, the bo of myce1iageednated frOm cOnidia of Prtubo mp was Observd Whe the mixtUr of CS-l l andcs-l2, aS well aS the COmPoUnd cs-7 were Presot. And the mtw of Cs-1l and cs-12shOwed grOWth-inhibitory activity ofendothlial cells and NIH-3T3 fibrobast in the.

稻瘟霉活性筛选结果显示CS-11和CS-12的混合物、CS-7具有使稻瘟霉孢子菌丝体变形的作用；体外药理实验显示，CS-11和CS-12的混合物具有显著的体外抑制血管内皮细胞生长作用及抑制血管成纤维细胞生长作用。

The concept of equivalent rotationally rigidity is offered and the formula of rotationally rigidity is obtained.

主要做了如下几个方面的工作：对伸臂位于顶部的单层框架—筒体模型进行分析，提出了等效转动约束的概念和转动约束刚度的表达式。

Male cats normally do not need aftercare with the exception of the night after the anesthetic.

男猫通常不需要善后除了晚上的麻醉。
