It is transmitted in seeds, parasitic weeds (like dodder) and is moved from plant to plant via aphids and mechanically (it is semi-stable). Baby Blue Eyes. Mosaic viruses are often seed borne (especially from home saved seed, so be careful where you get it from). Burpee Recommends: Be very careful when handling plants. Plants grown from infected seed are usually stunted and yield poorly, but plants infected by aphids may still produce well (though the seed will be infected and shouldn’t be saved for replanting).

The leaves had symptoms of vein clearing with the veins appearing white, with chlorotic spotting and distortion (Fig. Symptoms caused by the virus are mostly mosaic symptoms on leaves and leaf distortions. Many are transmitted by vegetative propagation of plant material from infected plants. Depending upon the age, variety and health of plant, conditions and strain of virus, they may not have a significant effect on the plant (or perhaps slowing growth slightly) or they may cause stunting and severely reduce the harvest. The new virus was given the tentative name Watercress white vein virus. If watercress is growing near cultivated lands, these viruses could infect and damage crops.

Turnip mosaic virus (TuMV) was isolated from infested leaves of watercress (Rorippa nasturtium-aquaticum [Nasturtium officinale]) sold in markets in Venezuela. This disease is spread by aphids who basically inject the plants to get sap and spread it from plant to plant. Pathogenicity tests were conducted on healthy watercress plants and the observed disease symptoms were identical to those first observed in watercress. Further testing by sap inoculation followed. Example first frost date on November 01. The new virus is a Tymovirus related to Turnip yellow mosaic virus (TYMV). Mosaic virus can overwinter on crop debris so it is important to clean up after harvest.

Five different viruses were isolated from parsley plants showing various virus-like symptoms and were identified as celery mosaic virus, carrot mottle virus, alfalfa mosaic virus, nasturtium ringspot virus and cucumber mosaic virus or strains of these. The new virus is a tymovirus related to Turnip yellow mosaic virus (TYMV). mosaic virus (BYMV) is an aphid-transmitted non-persistent potyvirus with a wide host range (Parr ella and L anave, 2009). Each virus had three sedimenting components, top (T), middle (M) and bottom (B), indistinguishable from those of cowpea mosaic virus (CPMV) in co-sedimentation experiments. Nasturtium officinale (watercress) is a semi-aquatic, high value, leaf and stem crop.
