Our results suggest that glucose-trimming was involved in cell wall integrity, polarity, septation and conidiation in A. fumigatus, probably by affecting proper localization and function of the proteins that are required for cell wall synthesis and actin re-organization.

本实验表明，烟曲霉的葡萄糖加工与细胞壁完整性、极性生长、分隔以及孢子的生成有关。N-糖链加工缺陷所导致的参与细胞壁合成及肌动蛋白细胞骨架重排的蛋白不能正常定位和失去功能可能是引起这些现象的原因。

Monosomic 3, monosomic 5, monosomic 10, trisomic 4 and trisomic 5 as experiment materials, their meiosis behavior of pollen mother cell, pollen characteristics, physiological and biochemical characteristics of anther, section observation of pollen development and the structure of embryo sac were studied, and the effects on the seed set and transmission rate were analyzed.

本文以大白菜同源四倍体小孢子培养产生的且已鉴定为3号单体、5号单体、10号单体、4号初级三体、5号初级三体的非整倍体株系及二倍体株系等为试材，对各材料的结籽率、雄配子传递率进行了统计，并对花粉母细胞减数分裂行为、花粉特性、花粉发育和胚囊结构以及花药生理生化特性等方面进行了观察研究，进而分析了其对大白菜单体n-1雄配子和三体n+1雄配子传递率的影响。

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。

The myxobacteria have a life cycle that is dominated by social behavior. During vegetative growth, cells prey on other bacteria in large groups by gliding motility. When faced with starvation, cells form a macroscopic fruiting body containing thousands of resting myxospores.

粘细菌运动、发育相关基因的克隆及分析粘细菌以具有复杂的多细胞社会学行为著称，它们能够在营养丰富的条件下在固体表面上滑行运动；又能在饥饿的条件下聚集形成子实体结构以及抗逆性的粘孢子。

From 94 soil samples and 9 bark samples in these areas, 259 Myxobacteria strains were isolated and 140 strains of them were purified. These 259 Myxobacteria strains were primarily identified in genus or species level by their fruiting bodies, myxospores and vegetative cells on the base of Sergey's manual of determinative bacteriology and they belonged to 9 genera(Myxococcus, Corallococcm. Angiococcus. Archangium, Cystobacter. Stigmatella . Hapoangium. Nannocystis. Polyangium) of Myxococcales.

根据菌株的特征性子实体形态和其营养细胞、粘孢子形态，以《Bergey's manualof determinative bacteriology》第九版为依据，将分离纯化出的菌株初步鉴定到属，这259株粘细菌菌株经过初步的分类鉴定，分属于9个属，即粘球菌属139株、珊瑚球菌属20株、囊球菌属18株、原囊菌属21株、孢囊杆菌属5株、标桩菌属36株、单囊菌属9株、小囊菌属3株，和多囊菌属8株。

A special arc or ring of cells in the sporangia of ferns that constitutes the mechanism for spore dispersal.

某些蕨类植物所具有的一种与孢子萌发机制有关的，孢子囊细胞壁上的一种特化的环状或弧状结构。

The results proposed that the abnormalities of microsporocytic cytoplasm or pollen exine, rather than the tapetal development caused the pollen abortion of Peiai 64S.

据此认为，培矮64S的花粉败育可能是由小孢子母细胞或花粉外壁的异常发育造成的，而不是由绒毡层发育引起的。

The Actinobacteria are distinguished by producing actinospres: entire cells encysted in thick walls to form resistant spores.

放线菌的特征是能够产生放线菌孢子，它是一种被囊的具有厚壁的完整细胞，具有一定的抵抗能力。

Any of a large group of single-celled, usually microscopic, eukaryotic organisms, such as amoebas, ciliates, flagellates, and sporozoans.

原生动物大批单细胞的，通常要在显微镜下才能看到的真核细胞有机体中的任何一种，包括变形虫、纤毛虫和孢子虫

For metabolites of strain SIPI-800, three active compounds were found, named as SIPI-800-1, 2 and 3 respectively, moreover SIPI-800-1 was new compound showing immunosuppressant activity and moderate anti- anaerobic activity; 2 and 3 were isoflavones with estrogenic activity, attracting activity to fungal zoospores, inhibiting alcohol dehydrogenase and aldehyde dehydrogenase I activities.

对SIPI-800菌株的代谢产物研究，分离出3个活性化合物，分别命名为：SIPI-800-1、2和3，其中1化合物为文献没有报道的新化合物，具有免疫抑制活性（1ug/ml浓度抑制NK细胞88.9%的活性）和弱的抗厌氧菌活性；2和3为异黄酮化合物，分别为Daidzein和Genisten的7甲基化衍生物，具有雌激素活性、强吸引真菌游动孢子、抑制乙醇或醛脱氢酶等活性。
