Two years age , africa lost more than half its cassava crop - - a key source of calories - - to the mosaic virus 两年前，花叶病毒使非洲损失了超过一半的木薯，而这种作物是当地人的主要食物。
The influence of defense enzymes activity of incompatible and compatible interactions between corn and sugarcane mosaic virus - maize dwarf strain b 玉米与矮花叶病毒互作对防御反应酶系活性的影响
Turnip mosaic virus ( tumv ) and cucumber mosaic virus ( cmv ) are two worldwide spread plant rna viruses , whose damages to host plants are utmost serious 芜菁花叶病毒( turnipmosaicvirus ， tumv )和黄瓜花叶病毒( cucumbermosaicvirus ， cmv )是两种世界范围内分布极为广泛、危害极为严重的植物病毒。
Up to date , the cauliflower mosaic virus ( camv ) 35s promoter and its derivatives are used commonly . no report show transgenic plants expressed badh from halophyte and using its own promoter or other strong promoters 目前在遗传工程中所用的启动子多为35s ，还没有高效胁迫诱导启动子的实际运用的报道。
Vp53 / vp37 genes have similar positions in rna2 to 58 - kd / 48 - kd movement protein ( mp ) genes of cowpea mosaic virus ( cpmv ) and encoded conserved motif of " 30k super group " mp 通过与同科的豇豆花叶病毒( cpmv )基因组编码区的比较发现， vp53 vp37与cpmv58 - kd 48 - kd移动蛋白的编码位置相同并存在一定同源性，并且vp53 vp37内含有病毒移动蛋白特有的“ 30k超组”保守模体。
Abstract : tobacco mosaic virus plays an very important role in the discovery of virus and several pioneers made contributions to the developmental process of virology , through which the brief history of discovery of virus can be traced 文摘:烟草花叶病病毒在病毒的发现中有着极其重要的地位，几位病毒学研究的先驱在这方面的研究有极大的贡献，以此为线索可以看到病毒被发现的简要历史。
Upon inoculation of cucumber mosaic virus ( cmv ) , the symptom development in the transgenic plants was delayed , one week later than that of the non - transgenic control , and the symptom on the transgenic plants were much milder Pcr反应以及southern杂交实验表明，外源基因片段已经插入到番茄的染色体中。用黄瓜花叶病毒cmv接种转基因番茄植株，其症状出现的时间比非转基因番茄对照要延迟7天左右。
Turnip mosaic virus ( tumv ) is a member of the potyvirus genus . it occurs worldwide and can infect more than 300 species in 156 genera of 43 plant families . it was found to be one of the most important ( only second to cucumber mosaic virus ) 芜菁花叶病毒（ tumv ）是植物病毒中最大的属? ?马铃薯y病毒属的一个重要成员，在世界范围内广泛分布，能侵染43科、 156属的300多种植物，其为害仅次于黄瓜花叶病毒（ cmv ） 。
We have created transgenic tobacco plants in which expression of the atnced3 coding region is under strong constitutive 35s cauliflower mosaic virus ( 35s ) promoter , stress - inducible rd29a promoter or stomotal - specific kst1 promoter by agrobacterium tumefaciens - mediated transformation 构建了组成型35s 、诱导型rd29a 、气孔特异表达性kst1启动子驱动atnced _ 3基因表达的真核表达载体，通过农杆菌介导的叶盘法转化烟草，得到了转基因植株。
An antisense molecular beacon ( mbl ) was designed for the dctonninon of the genome rna of tobacco mosaic virus with no need of stringen isolation and purification of the virus prtc1es and rna as well , which benefited from the proininen specificity and selectivity of molecular beacon 凝g胶中的存在状态，发现酶分子在溶胶凝胶中象在水溶液中一样均匀分布，且不影响活k性。辣根过氧化物酶（ hrp ）和葡萄糖氧化酶（ god ）都能成功地包埋于其中。
