| effect of host plant tissue on the vector transmission of grapevine leafroll-associated virus 3. | many biotic and abiotic factors affect the transmission efficiency of vector-borne plant pathogens. insect vector within-plant distribution and host tissue preference are known to affect pathogen acquisition and inoculation rates. in this study, we first investigated whether feeding tissue affects the transmission of grapevine leafroll-associated virus 3 by planococcus ficus (signoret) (hemiptera: pseudococcidae) and the effect of mealybug within-plant distribution on virus transmission under gr ... | 2011 | 22066175 |
| interactions within susceptible hosts drive establishment of genetically distinct variants of an insect-borne pathogen. | coinfections are common, leading to pathogen interactions during transmission and establishment in a host. however, few studies have tested the relative strengths of pathogen interactions in vectors and hosts that determine the outcome of infection. we tested interactions between two genetically distinct variants of the mealybug-transmitted grapevine leafroll-associated virus 3. the transmission efficiency of each variant in single variant inoculations by two vector species was determined. the e ... | 2015 | 26470292 |
| infection and colonization of nicotiana benthamiana by grapevine leafroll-associated virus 3. | grapevine leafroll disease is an increasing problem in all grape-growing regions of the world. the most widespread agent of the disease, grapevine leafroll-associated virus 3 (glrav-3), has never been shown to infect species outside of the genus vitis. virus transmission to several plant species used as model systems was tested using the vine mealybug, planococcus ficus. we show that glrav-3 is able to infect nicotiana benthamiana. working with glrav-3 infected n. benthamiana revealed distinct a ... | 2017 | 28710957 |
| transmission of grapevine leafroll-associated virus 3 by the vine mealybug (planococcus ficus). | grapevine leafroll disease is caused by grapevine leafroll-associated viruses (glravs). within this virus complex, glrav-3 is the predominant species in the world. several glravs have been shown to be transmitted from vine to vine by mealybugs although a detailed characterization of transmission biology is lacking. the introduction of the vine mealybug (planococcus ficus) in california and other regions of the world may result in increasing disease incidence of established glravs. we studied the ... | 2008 | 18943455 |
