| 5. | Generally speaking , the content of k in soil , ph of the soil , altitude and the content of hygroscopic water are the most critical factors to cause the morphological differentiation of e . chloranthoides yang 从总体上看,对形态性状影响最大的几个环境因子是全钾、土壤ph值、海拔、吸湿水的含量。 |
| 6. | Their life cycles and characteristics of their colonies were observed and strain s - l was found to have the typically morphological differentiation of a . yumaense . the morphological differences of every mutants and the period of morphological block were ascertained 尤马马杜拉放线菌( actinomadurayumaense )是马杜霉素( maduramicin )的产生菌,有明显的产素不稳定性,影响工业生产。 |
| 7. | Streptomyces are mycelial multicellular soil actinomycetes in which adverse environmental conditions induce a developmental program involving complex morphological differentiation coordinated with synthesis of an enormous variety of interesting and useful secondary metabolites 链霉菌是丝状多细胞土壤放线菌,土壤逆环境诱导链霉菌具有复杂形态分化生命周期,获得合成大量有用次生代谢物能力。 |
| 8. | The results suggest that visual experience has a facilitating effect on morphological differentiation of bipolar cells , and early mature bipolar cells could provide light dependent signals to guide synaptic connections of ganglion cells in the inner retina 本篇结果证明了视觉经验可促进双极细胞的形态发育,并可进而推论早期成熟的双极细胞提供了光传入视网膜的讯号,再进一步去影响内层视网膜中神经节细胞在发育过程中的突触连结。 |
| 9. | The differentiation of the studied morphological characters shows that the differentiation of vegetative organs is greater than that of reproductive organs and the differentiation of reproductive organs does n ' t reach the notable level , which indicates that the morphological differentiation mainly occurred in the vegetative organs and is caused mainly by environment factors 在所研究的形态性状中,其差异程度表现出:营养器官的变异大于生殖器官的变异,所测量的生殖器官性状的变异均没达到显著水平,这说明形态分化主要表现在营养器官特征上,也说明营养器官受环境影响较大。 |
| 10. | Glial cell line - derived neurotrophic factor ( gdnf ) was originally isolated based on its potent and specific ability to promote the survival and morphological differentiation of dopaminergic neurons and motoneurons in embryonic midbrain cultures . in addition , gdnf also support the survival and regulate the differentiation of many peripheral neurons , including sympathetic , parasympathetic , sensory and enteric neurons . gdnf also plays a crucial role outside the nervous system , as a morphogenetic factor in kidney development and as a regulator of spermatogonia differentiation Gfr 1与gdnf结合位点的研究胶质细胞源性神经营养因子( gdnf )对多巴胺能神经元、运动神经元、感觉神经元、肠道神经元等多种神经元具有促进存活及保护作用,它还能促进肾脏的发育和精原细胞的成熟,因此,极有希望用于治疗神经损伤和神经系统退行性病变。 |
