βC1 is a pathogenicity determinant: not only for begomoviruses but also for a mastrevirus [PDF]

Archives of Virology, 2014
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.

F‐actin dynamics in midgut cells enables virus persistence in vector insects

Molecular Plant Pathology, Volume 23, Issue 11, Page 1671-1685, November 2022., 2022
Biphasic dynamics of F‐actin mediated by the ADF–CP interaction may play an important role in controlling virus entry and the virus accumulation level required for persistent transmission while maintaining the health of the vector. Abstract Hemipteran insects that transmit plant viruses in a persistent circulative manner acquire, retain and transmit ...

Deep Sequencing Data and Infectivity Assays Indicate that Chickpea Chlorotic Dwarf Virus is the Etiological Agent of the “Hard Fruit Syndrome” of Watermelon

Viruses, 2017
Chickpea chlorotic dwarf virus (CpCDV), a polyphagous mastrevirus, family Geminiviridae, has been recently linked to the onset of the “hard fruit syndrome” of watermelon, first described in Tunisia, that makes fruits unmarketable due to the presence of ...

Inducible resistance to maize streak virus. [PDF]

PLoS ONE, 2014
Maize streak virus (MSV), which causes maize streak disease (MSD), is the major viral pathogenic constraint on maize production in Africa. Type member of the Mastrevirus genus in the family Geminiviridae, MSV has a 2.7 kb, single-stranded circular DNA ...

Appearances can be deceptive: revealing a hidden viral infection with deep sequencing in a plant quarantine context. [PDF]

PLoS ONE, 2014
Comprehensive inventories of plant viral diversity are essential for effective quarantine and sanitation efforts. The safety of regulated plant material exchanges presently relies heavily on techniques such as PCR or nucleic acid hybridisation, which are

Emerging wild virus of native grass bioenergy feedstock is well‐established in the Midwestern USA and associated with premature stand senescence

GCB Bioenergy, Volume 14, Issue 4, Page 463-480, April 2022., 2022
Switchgrass (Panicum virgatum) is a native North American prairie grass being developed as a new bioenergy crop. New crops may be attacked by novel or previously unrecognized pathogens. We studied the potential extent of switchgrass crop infection by a recently‐discovered virus species called Switchgrass mosaic virus by surveying mature stands ...

Experimental evidence indicating that mastreviruses probably did not co-diverge with their hosts

Virology Journal, 2009
Background Despite the demonstration that geminiviruses, like many other single stranded DNA viruses, are evolving at rates similar to those of RNA viruses, a recent study has suggested that grass-infecting species in the genus Mastrevirus may have co ...

Detection and Molecular Characterization of Chickpea Chlorotic Dwarf Virus and Tomato Leaf Curl New Delhi Virus in Morocco

Horticulturae, 2022
The chickpea chlorotic dwarf virus (CpCDV) (from the genus Mastrevirus and the family Geminiviridae) and tomato leaf curl New Delhi virus (ToLCNDV) (from the genus Begomovirus and the family Geminiviridae) represent an important threat to different crops

Identification of an RNA silencing suppressor encoded by a mastrevirus

Journal of General Virology, 2014
Wheat dwarf virus (WDV) is a DNA virus belonging to the genus Mastrevirus of the family Geminiviridae. In this study, we report that the Rep protein encoded by WDV is a RNA silencing supressor as determined by co-infiltration assays using transgenic Nicotiana benthamiana line 16c carrying the GFP reporter gene. The Rep protein was shown to inhibit both

MASTREVIRUS EFFECT ON METABOLIC AND BIOLOGICAL ACTIVITIES IN TOMATO LEAVES

The Journal of Animal and Plant Sciences, 2023
This study was planned to illuminate the secondary metabolites of Chickpea chlorotic dwarf virus (member of mastrevirus) infected tomato plants by using phytochemical profiling procedures and their comparison with control healthy tomato plants.
