ILARVIRUSES Meaning and
Definition
-
Ilarviruses are a genus of plant viruses that belong to the family Bromoviridae. These viruses are named after the type species of the genus, "Ilarvirus prunus necrotic ringspot virus". Ilarviruses are primarily known for their ability to infect various fruit trees, including apple, pear, peach, and plum, causing significant economic damage to orchards worldwide.
Ilarviruses are characterized by their small, isometric virions which have a diameter of around 30 nm. They possess a positive-sense, single-stranded RNA genome that is 8-9 kilobases in length. The genome encodes for three major proteins that are essential for viral replication and movement within the host plant.
Symptoms of ilarvirus infection vary depending on the host plant species, but commonly include necrotic rings or spots on leaves, fruits, and stems. Leaf curling, stunting of growth, and reduced yields are also observed in infected plants. These viruses are primarily transmitted through grafting or mechanical means, such as pruning tools, but some species can also be spread by aphids or other sucking insects.
Management of ilarvirus infections relies on the use of clean planting material, strict quarantine measures, and eradication of infected plants. There are currently no effective chemical treatments available to control these viruses. Several resistant plant cultivars have been developed to mitigate the impact of ilarviruses on fruit production.

Etymology of ILARVIRUSES
The word "Ilarviruses" is derived from the genus name "Ilarvirus". The term Ilarvirus was coined by combining the initials of the names of two plant diseases: Ilar, derived from 'Illinois Light Autochrome Ringspot,' and CVA, derived from 'Cherry Virus A.' The name was chosen to represent the nature of the viruses as well as their association with plant diseases.
