| 1. | The entire shoot apex of a horsetail could fit into the large apical cell in the growing tip of a fern .
木贼的整个茎尖可相当于蕨类生长锥中大的顶端细胞。 |
| 2. | If the borer has been properly located and drilled into the pith, a record of growth and age is obtainable for that position on the tree .
如果生长锥放的位置适当，钻入木髓即可得到树木那个部位的生长记录和年龄。 |
| 3. | Utilization deffirent growth awl shape of rice to forcasting flowerscence
利用水稻生长锥形态差异预测花期 |
| 4. | Similarly , xenopus spinal growth cones turned away from a gradient of baclofen , an agonist of the gabab receptor
同样的， gabab受体的激动剂baclofen的浓度梯度也能够吸引或排斥爪蟾脊髓神经元的生长锥。 |
| 5. | In mature neuronal network , nogo - a immunoreactive axons showed a string of beads which correspond to the varicosities or growth cones
Nogo a在成熟的神经元网状的突起上，呈串珠样分布，这些结构推测为膨体或生长锥。 |
| 6. | Thus , gpcrs can mediate both repulsive and attractive axon guidance in vitro , and chemokines may serve as guidance cues for axon pathfinding
因此， g蛋白耦联受体可以介导生长锥的吸引或排斥反应，并且chemokine也能作为导向因子指导生长锥转向。 |
| 7. | Then , nogo - a expression was gradually enriched in the distal segment and growth cone of the putative axon which grew much faster than other neurites
神经元突起形成过程中， nogo a主要表达于树突近端，在轴突上随着轴突的伸长逐渐表达于轴突远端和生长锥。 |
| 8. | Because the charge must be released by the silicon neuron and sensed by the silicon growth cone simultaneously , the softwires end up connecting neurons that are active at the same time
因为矽神经元释出的电荷必须同时被矽生长锥侦测到，结果软线就将同时活跃的矽神经元连结在一起。 |
| 9. | Under normal culture conditions , pkc - dependent repulsion dominated , but the repulsion could be converted to attraction by inhibiting pkc or by elevating cytosolic cgmp
通常条件下， pkc通路介导了生长锥排斥反应，而ip3通路介导了吸引反应，由于pkc通路占据主导， sdf - 1和baclofen排斥生长锥。 |
| 10. | Agrin inhibits rac activity in developing neurons and expression of dominant negative rac1 abolishes agrin - induced growth cone turning and substantially inhibits neurite extension
我们的实验也表明， agrin抑制发育中神经元rac的活性。 dn - rac1的表达完全阻断了agrin引起的生长锥导向，并抑制突起的生长。 |
