[1] It causes spots on leaves and colored streaks on flowers.

[1] If a plant is also infected with the Cymbidium mosaic virus, it can lead to a condition called blossom brown necrotic streak.

[1] Its genome has been sequenced and contains approximately 6600 nucleotides organized into four open reading frames.

[2][3] Its similarity to other tobamoviruses can be seen from the genetic data and the (limited) ability of a Tobacco mosaic virus modified to contain ORSV movement protein to infect tobacco.

[4] However, only about 60% of the nucleotides in ORSV are identical with Tobacco mosaic virus.
