| the role of some weeds as hosts of capsicum viruses in the rift valley parts of ethiopia. | hot pepper (capsicum annuum. l.) is a traditionally and economically important spice crop in ethiopia. chronic infection with viruses is reported as major constraint, that often force farmers to ban its production. however, epidemiological studies on these viruses are lacking in the country. knowledge of the weed flora as virus reservoir is essential to reduce the spread of plant viruses. the potential role of some frequently and abundantly occurring weed species as host plants for capsicum viru ... | 2002 | 12701434 |
| dna abrasion onto plants is an effective method for geminivirus infection and virus-induced gene silencing. | geminiviruses belong to a rapidly growing group of plant pathogens that contribute to crop losses in tropical and subtropical areas of the world. geminivirus infection is a model for plant dna replication and virus/host interactions. geminiviruses are also used as vectors to induce silencing of endogenous genes in several plant species. a method was analyzed for inoculating geminiviruses using plasmid dna rubbed onto leaves in the presence of an abrasive (dna abrasion). although the use of dna a ... | 2007 | 17337069 |
| one-pot fabrication of silver nanocrystals using nicandra physalodes: a novel route for mosquito vector control with moderate toxicity on non-target water bugs. | mosquitoes (diptera: culicidae) as vectors for important diseases and parasites causing millions of deaths every year. the use of synthetic pesticides against culicidae leads to resistance and environmental concerns. therefore, eco-friendly control tools are a priority. in this research, nicandra physalodes-mediated synthesis of silver nanoparticles (ag nps) was conducted, in order to control larval populations of three important mosquito vectors, anopheles stephensi, aedes aegypti and culex qui ... | 2016 | 27473981 |
