The ecological functions of arbuscular mycorrhizal fungi in natural and agroecosystem was greatly concerned in recent decades.

泡囊丛枝状菌根真菌(Arbuscular Mycorrhizal Fungi，AMF)对植物营养吸收和对重金属污染的土壤的生态恢复功能是近年来人们关注的热点问题，有关AMF对植物多样性的影响及对被Pb污染土壤的修复的研究已有了较多的报道。

Strains arbuscular mycorrhizal fungi were used to study the effects on cucumber growth, yield and quality of fruit in organic soil and ordinary soil cultivation under greenhouse.

Three protozoa (Bodo edax, Colpoda cucullus, Amoeba proteus) were isolated from soil. The porous simulation with glass bead, soil column and root box incubation experiments were made to study the association of protozoa movement with phosphorus translocation and its influencing factors. The effects of protozoa on corn growth and corn straw mineralization were also involved. The results showed that protozoa movement in glass bead column was greatly controlled by the pore sizes. Bodo edax, about 5-7 m, could pass through the pores of 28-20 11 m in diameters. Colpoda cucullus (30-60 m) could move through the pores of 155~116 m. However, no Amoebaproteus(100~150 m) was found in the effluents from all the columns. All the three protozoa made 32P redistribution in soil column.

本研究利用土壤中常见的3种原生动物(梨波豆虫Bodo edax、僧帽肾形虫Colpoda cucullus、大变形虫Amoeba proteus)，通过玻璃珠孔隙模拟、土柱及根箱培养试验，研究3种原生动物运动与磷素运移之间的关系及其影响因素，以及原生动物对玉米磷素营养的影响，同时对3种原生动物在玉米秸秆分解中的作用做了初步的探索，研究结果表明：原生动物的运动与孔隙密切相关，Bodo edax(5～7μm)能够穿过28～20μm孔隙，Colpoda cucullus (30～60μm)只能穿过155～116μm的孔隙，而Amoeba proteus(100～150μm)不能从玻璃柱中流出。

Objective To study the levels of brain-derived neurotrophic factor protein in experimental dogs using multiple cauda equina constrictions throughout the entire lumbar, sacral and coccygeal spinal cord and their central processes of the dorsal root ganglia neurons resulting in the acute and severe cauda equina syndrome.

目的研究实验性犬急性重度马尾神经压迫48h的相关脊髓和背根神经节（dorsal root ganglion，DRG）内脑源性神经营养因子（brain-derived neurotrophic factor，BDNF）蛋白表达水平。

RT-PCR analysis showed that GhMADS1 gene expressed in petals, stamens, ovules and fibers, but not in roots, stems, leaves, bracts and sepals. The strongest expression of GhMADS1 gene was detected in petals. But in floral buds of a cotton homeotic mutant (CHV1), whose floral organs are all converted to bract leaf-like organs, the transcript of GhMADS1 gene was not detected.

RT-PCR分析显示，该基因在陆地棉的花瓣、雄蕊、胚珠和纤维中表达，特别是在花瓣中表达量最高，而在根、茎、叶等营养器官和棉花同源异型突变体CHV1（所有花器官均变为苞叶状叶性器官）的变异花蕾中不表达。
