| tomato chlorosis virus: a new whitefly-transmitted, phloem-limited, bipartite closterovirus of tomato. | abstract tomato chlorosis virus (tocv) is the second whitefly-transmitted, phloem-limited, bipartite closterovirus described infecting tomato. tocv is distinct from tomato infectious chlorosis virus (ticv), based on lack of serological and nucleic acid cross-reactions and differences in vector specificity. ticv is transmitted only by the greenhouse whitefly (trialeurodes vaporariorum), whereas tocv is transmitted by the greenhouse whitefly, the banded-wing whitefly (t. abutilonea), and bemisia t ... | 1998 | 18944918 |
| co-infection by two criniviruses alters accumulation of each virus in a host-specific manner and influences efficiency of virus transmission. | tomato chlorosis virus (tocv), and tomato infectious chlorosis virus (ticv), family closteroviridae, genus crinivirus, cause interveinal chlorosis, leaf brittleness, and limited necrotic flecking or bronzing on tomato leaves. both viruses cause a decline in plant vigor and reduce fruit yield, and are emerging as serious production problems for field and greenhouse tomato growers in many parts of the world. the viruses have been found together in tomato, indicating that infection by one criniviru ... | 2008 | 19000010 |
| the complete nucleotide sequence of the rna2 of the crinivirus tomato infectious chlorosis virus: isolates from north america and europe are essentially identical. | the complete nucleotide sequences of the rna2 of two isolates of tomato infectious chlorosis virus (ticv, genus crinivirus, family closteroviridae) from the united states and spain, respectively, were determined. the sequences of both isolates were found to be nearly identical. ticv rna2 consisted of 7,914 nucleotides in both isolates and contains eight open reading frames that encompass the closteroviridae hallmark gene array represented by a heat shock protein 70 family homologue, a protein of ... | 2009 | 19288051 |
| the complete nucleotide sequence and genome organization of tomato infectious chlorosis virus: a distinct crinivirus most closely related to lettuce infectious yellows virus. | the complete nucleotide sequence of tomato infectious chlorosis virus (ticv) was determined and compared with those of other members of the genus crinivirus. rna 1 is 8,271 nucleotides long with three open reading frames and encodes proteins involved in replication. rna 2 is 7,913 nucleotides long and encodes eight proteins common within the genus crinivirus that are involved in genome protection, movement and other functions yet to be identified. similarity between ticv and other criniviruses v ... | 2009 | 19575276 |
| rapid discrimination of tomato chlorosis virus, tomato infectious chlorosis virus and co-amplification of plant internal control using real-time rt-pcr. | tomato chlorosis virus (tocv) and tomato infectious chlorosis virus (ticv) (genus: crinivirus, family: closteroviridae) are two emergent whitefly-transmitted viruses that have been associated with yellowing symptoms of tomato crops during the last two decades. a real-time, one-step reverse transcription (rt) taqman(®) polymerase chain reaction (pcr) assay was developed and optimized for the multiplex detection of ticv, tocv and an internal control of mitochondrion cytochrome oxidase subunit i ( ... | 2011 | 21663765 |
| simultaneous detection of the seven main tomato-infecting rna viruses by two multiplex reverse transcription polymerase chain reactions. | cucumber mosaic virus, tomato spotted wilt virus, tomato mosaic virus, tomato chlorosis virus, pepino mosaic virus, torrado tomato virus and tomato infectious chlorosis virus cause serious damage and significant economic losses in tomato crops worldwide. the early detection of these pathogens is essential for preventing the viruses from spreading and improving their control. in this study, a procedure based on two multiplex rt-pcrs was developed for the sensitive and reliable detection of these ... | 2012 | 22939978 |
| major tomato viruses in the mediterranean basin. | tomato (solanum lycopersicum l.) originated in south america and was brought to europe by the spaniards in the sixteenth century following their colonization of mexico. from europe, tomato was introduced to north america in the eighteenth century. tomato plants show a wide climatic tolerance and are grown in both tropical and temperate regions around the world. the climatic conditions in the mediterranean basin favor tomato cultivation, where it is traditionally produced as an open-field plant. ... | 2012 | 22682165 |
| epidemiology and genetic diversity of criniviruses associated with tomato yellows disease in greece. | tomato chlorosis virus (tocv) and tomato infectious chlorosis virus (ticv) are two whitefly transmitted viruses which are classified in the genus crinivirus of the family closteroviridae. both induce similar yellowing symptoms in tomato and are responsible for severe economic losses. tocv is transmitted by bemisia tabaci gennadious, trialeurodes vaporariorum westwood and trialeurodes abutilonea haldeman, whereas ticv is transmitted only by t. vaporariorum. an extensive study was conducted during ... | 2014 | 24370865 |
