[4] The Ophioviridae viruses are characterized by a flexible and elongated nucleocapsid that is composed mostly of filamentous structures and is helically symmetrical.

It also has a non-enveloped protein capsid that is capable of coiling around itself allowing for a super-coiled structure and the helical symmetry.

B1MaV often remains asymptomatic for long periods of time after initial infection allowing for blind transmission.

[3] The virus can also become dormant in some areas of the plant and expressed in others, causing some leaves to display symptoms and others to be asymptomatic.

When a blueberry plant begins to show symptoms of infection by B1MaV a mild to severe mottle and mosaic patterns on foliage appears.

[2] The infection also causes late ripening of fruit, reduced yield of the crop, and poor quality of the berries, as the virus spreads throughout the plant and begins affecting cellular mechanisms.

[6] The population structure is highly conserved in B1MaV as a result of low genetic diversity among isolates of the virus.

[6] RNA 2 encodes for a 58 kDa movement protein that is thought to also be involved in the suppression of post transcriptional gene silencing.

These structures are likely involved in packaging of the genomic RNAs into their capsid or in long-distance interactions for transcription and translation.

The movement proteins that the virus encodes in RNA 2, often effect cellular mechanisms for transport to distant tissues in the plant.

Some characteristic symptoms of the disease include bark scaling in the trunk and main branches of an adult plant as well as internal staining in the underlying wood.

Citrus psorosis virus also has three negative stranded RNA sequences encased in a protein coat.

Just as in B1MaV, CpsV is graft transmissible and also appears to remain asymptomatic for the first several years of infection.

As with B1MaV, the lettuce ring necrosis virus spreads via soil transmission through fungal zoospores, and the symptoms in the plant often do not appear for several weeks to months after infection.
