| 4. | In this paper , signal peptide was added before the n - terminus of cema with the intention to reduce its toxic to plant cells while maintaining the strong antibacterial activity 本文通过在cema的n端添加信号肽,对其进行改造,以探索不降低抑菌作用的同时,降低其对植物细胞毒害作用的可能性。 |
| 5. | In the cema algorithm , three color edge detection operators in vertical , horizontal and diagonal directions are employed separately to obtain three edge images from the original image , 在提取出图像内的文字区域后,本文运用纹理修复技术,将提取出的文字从原图中去除,同时,修复原图中被文字所遮挡的背景区域。 |
| 6. | 2 . obtaining of mcema ( modified cema ) and plant defensin afp gene mcema ( 141bp ) was amplified with pucspcema plasmid as template and p5 , p4 as primers , and plant expression vector pemcema was constructed Mcema和植物防御素基因的pcr合成以经测序验证的spcema为模板,用p _ 5和p _ 4扩增得到了全长141bp的mcema ,并构建了植物表达载体pemcema 。 |
| 7. | Plant defensin disrupts the cell membrane of phytopathogen differently from cema that contacts directly with the cell membrane . plant defensins are thought to interact with specific receptor harboring in the cell membrane 由于对真菌,特别是丝状真菌有很强的抑制作用,而对植物细胞没有毒害作用,防御素有望在植物抗病基因工程中得到广泛应用。 |
| 8. | Cationic antibacterial peptides are found in insect , animal and plant . they are grouped into four classes including cecropins , magainins , melittins and defensins . cema consists of eight amino acid from n - terminus of cecropin a and c - terminus of modified melittin 阳离子抗菌肽是一类广泛存在于昆虫、动物、植物体内的小分子抗菌活性多肽,大体可分为:杀菌肽( cecropin ) 、蛙皮素( magainin ) 、蜂毒素( melittin ) 、防御素( defensin )等四大类。 |
| 9. | Construction of plant binary expression vector peasp in consideration of the different cell membrane disruption mechanism of plant defensin and cema , plant binary expression vector peasp were constructed . simultaneous expression of cema and afp may synergistically inhibit the growth of phytopathogens that are the main cause agent of agricultural loss 构建了双价抗菌肽基因植物表达载体peasp鉴于植物防御素与cema的空间结构、作用机制有所不同,两者在植物中的同时表达,有可能对病源真菌有协同抑制作用,构建了双价植物表达载体peasp 。 |
| 10. | They inhibits the growth of fungi ( filamentous fungi especially ) while are non - toxic to plant cells . the main results were as follows : 1 . obtaining of spcema ( signal peptide modified cema ) spcema ( 187bp ) was amplified with two long complementary primers ( p2 and p3 ) and two primers ( pl and p4 ) containing restriction enzyme recognition site 带信号肽cema基因的pcr合成以两条部分重叠长链引物p _ 2和p _ 3延伸产物为模板, p _ 1和p _ 4为正、反引物进行pcr扩增,获得了改造的抗菌肽基因spcema ( 187bp ) 。 |
