Virus aggregates and pinwheels in plants infected with mite-transmitted ryegrass mosaic virus [PDF]

open access: yes, 1973
Mulligan (1960) reported that ryegrass mosaic virus (RMV) had long rod-shaped particles that were often broken in preparation. Brandes (1964) confirmed the particle shape and determined a modal length of 703 nm and Brandes & Bercks (1965) placed RMV in ...

Efficiency of a chemo-thermotherapy technique for eliminating Arabis mosaic virus (ArMV) and Prunus necrotic ringspot virus (PNRSV) from in vitro rose plantlets

open access: yesJournal of Crop Protection, 2016
Mosaic is presumably the most commonly encountered viral disease in roses. We have developed chemo-thermotherapy for eliminating Arabis mosaic virus (ArMV) and Prunus necrotic ringspot virus (PNRSV) from rose plants.

Secoviridae: a proposed family of plant viruses within the order Picornavirales that combines the families Sequiviridae and Comoviridae, the unassigned genera Cheravirus and Sadwavirus, and the proposed genus Torradovirus [PDF]

open access: yes, 2009
The order Picornavirales includes several plant viruses that are currently classified into the families Comoviridae (genera Comovirus, Fabavirus and Nepovirus) and Sequiviridae (genera Sequivirus and Waikavirus) and into the unassigned genera Cheravirus ...
