| βc1 is a pathogenicity determinant: not only for begomoviruses but also for a mastrevirus. | βc1 proteins, encoded by betasatellites, are known to be pathogenicity determinants, and they are responsible for symptom expression in many devastating diseases caused by begomoviruses. we report the involvement of βc1 in pathogenicity determination of a mastrevirus. analysis of field samples of wheat plants containing wheat dwarf india virus (wdiv) revealed the presence of a full-length and several defective betasatellite molecules. the detected betasatellite was identified as ageratum yellow ... | 2014 | 25000899 |
| association of satellites with a mastrevirus in natural infection: complexity of wheat dwarf india virus disease. | in contrast to begomoviruses, mastreviruses have not previously been shown to interact with satellites. this study reports the first identification of the association of satellites with a mastrevirus in field-grown plants. two alphasatellite species were detected in different field samples of wheat infected with wheat dwarf india virus (wdiv), a cotton leaf curl multan alphasatellite (clcuma) and a guar leaf curl alphasatellite (glcua). in addition to the alphasatellites, a betasatellite, agerat ... | 2014 | 24719407 |
| a novel mastrevirus infecting wheat in india. | a new mastrevirus (family geminivridae) infecting wheat in india was detected by rolling-circle amplification (rca). the complete nucleotide sequence of the virus was determined to be 2783 bp long. analysis of the nucleotide sequence revealed identity and a genome organisation typical of a mastrevirus. an identical virus was detected in the candidate insect vector (leafhopper) collected from the field. agroinoculation of young wheat plants with an infectious clone of the virus resulted in dwarfi ... | 2012 | 22752839 |
