Arabis mosaic virus is a viral plant pathogen that is known to infect multiple hosts. The pathogen, commonly referred to as Armv, is from the Secoviridae family, and causes Raspberry yellow dwarf virus and Rhubarb mosaic virus. [1] The Arabis Mosaic virus infects multiple hosts, including strawberries, hop, hemp, grape and geraniums, raspberries, sugarbeets, celery, horseradish, lilac, peach and lettuces. [1] [2]
Symptoms
While it is common for the pathogens influence, there are some symptoms that can occur in the hosts. The most prevalent symptoms of ARMV are stunting of the plant and leaf flecking / molting [3] and leaf enations. [2] The symptoms will vary based on the type of rootstock, environmental conditions and variety. [2]
Disease Cycle
This virus is transmitted primarily through the soil by nematodes, but it can also be transmitted through the use of arthropods (such as insects), and through seed and pollen transmission. [4]Nepoviruses, nematodes, which are: Xiphinema, Longidorus and Paralongidorus . [3] For the Arabis Mosaic Virus, the Xiphinema diversicaudatum is the most common nematode vector. [3]In this cycle, females lay their eggs in the spring, which then hatch and the juveniles mature through four different stages (which can be distinguished by body length and functionality of odontostyles) and finally move into adulthood. Nematodes feed on the roots of the infected plants, taking the virus with them. The nematodes can only transmit the virus when they are adults, but they do not have the chance to re-uptake the virus from an infected root. [5]
Management
The best way to control the virus is to use virus-free planting material. [3] The pathogen can only be transmitted through the pathogenesis of the pathogenesis of the pathogenesis of the pathogenesis of the disease. [3] It is also important to know where plants have been previously infected. [4] These measures are important because they are not able to reduce the occurrence of nematodes, as they are able to reside in the roots of the plant. [5]
