Dasheen mosaic virus

Dasheen mosaic virus (DsMV) infecting three major edible aroids namely Amorphophallus paeoniifolius, Colocasia esculenta, and Xanthosoma sagittifolium cultivated in India was characterized. Infected plants showing typical DsMV symptoms were subjected to reverse transcription-polymerase chain reaction, and an amplification of a 963 bp fragment which. Dasheen mosaic virus (DsMV), first described by Zettler et al. in 1970 from dasheen (Co loca si aecu nt (L) Schott), is an aphid-transmitted virus assigned to the genus Potyvirus in the family Potyviridae. DsMV has a world wide distributio Dasheen mosaic virus infection in Alocasia, showing feathering along the veins in a small area of the leaf. Photo 5.

Dasheen mosaic was first documented by researchers in Florida (7) in 1970. Samples of Aglaonema, Caladium, Colocasia, Dieffenbachia, and Xanthosoma were found to be naturally in-fected with a flexuous rod-shaped virus. Sub-sequent investigations (6) have expanded the susceptible host range for DMV to include 13 genera in the Araceae family (see Table 2). DM Dasheen mosaic virus (DsMV) infecting three major edible aroids namely Amorphophallus paeoniifolius, Colocasia esculenta, and Xanthosoma sagittifolium cultivated in India was characterized Listed below are a few of the physical characteristics to look for when considering whether or not your plant has the Mosaic Virus: • Foliage that has spots, stripes or blisters in shades of yellow, white, or areas of dark green patches. • Leaves are curled, wrinkled or possess any other. Dasheen mosaic is an important and conspicuous viral disease of ornamental and edible aroids throughout the Pacific and worldwide. The pathogen, dasheen mosaic potyvirus (DsMV), was first recorded from dasheen (Colocasia esculenta (L) Schott) in 1970. Today, DsMV is a common and widespread pathogen of the aroid

Keywords: Amorphophallus paeoniifolius; Dasheen mosaic virus; Elephant foot yam; Potyvirus; RT-PCR Introduction Amorphophallus paeoniifolius or Elephant foot yam (Whitespot giant arum) is an important edible tropical tuber crop, belonging to the family Araceae. It is a crop of South-east Asian origin, grown widely in Philippines, Malaysia. Bedeutend sind der Taro-Large-Bacilliform-Virus (TLBV), der durch Spitzkopfzikaden (Fulgoromorpha) der Art Tarophagus proserpina übertragen wird, der Taro-Small-Bacilliform-Virus (TSBV), den die Art Planococus citri aus der Familie der Schmierläuse (Pseudococcidae) überträgt, und der Dasheen-Mosaic-Virus (DMV). Systematik. Colocasia esculenta ist eine von etwa 20 Arten in der Gattung.

The first slide you see is of malanga infected with dasheen mosaic virus. The disease is called dasheen mosaic. You can see that the leaf is a pattern of off colors, some darker, some lighter than normal. These alternating darker, lighter patterns are referred to as mottling. This is a quite common symptom associated with virus diseases. Obviously, you must be familiar with what a healthy malanga leaf looks like in order to detect this subtle symptom pattern in the dasheen mosaic virus. Dasheen mosaic virus (DsMV) is a potyvirus transmitted by aphids to many aroids (Zettler and Hartman 1987). The vegetative propagation of taro contributes to the widespread distribution of viruses in this crop (Kazmi et al. 2015). In December 2016, virus-like symptoms including feathery chlorotic mottling and distortions in leaves were observed on taro (cultivar Panikachu) growing in Chandpur. Replikationszyklus.

Dasheen mosaic virus (DsMV) is one of the important viral pathogen of C. esculenta, which develops pale green feathering symptoms, or may have severe or slight vein-banding symptoms or no visible symptoms at all. The virus causes variation patterns in colour, shapes, and sizes of the leaf and may reduce the corm yield. Symptom expression is often intermittent or seasonal. Alconero and Zettler. By comparing with known sequences of potyviruses, CLLV was identified as a new species of Potyvirus based on the uniqueness in the CP gene and 3' NCR. Soybean mosaic virus and Watermelon mosaic virus 2 are the potyviruses most similar to CLLV, but they share only approximately 80% nucleotide identity with CLLV in the CP and NCR regions The seven positive samples were used to perform an additional ELISA test using antiserum specific for dasheen mosaic virus (DsMV) (Agdia). All seven samples tested positive for DsMV. To confirm the identity of the virus, total RNA was extracted from the seven samples using the PureLink® Plant RNA Reagent Kit (Invitrogen, Carlsbad, CA). After DNA digestion with PerfeCta® DNase I (Qiagen, Beverly, MA), the RNA was used to perform reverse transcription polymerase chain reaction (RT. Cucumber leaves afflicted with various stages of Cucumber mosaic virus A mosaic virus is any virus that causes infected plant foliage to have a mottled appearance. Such viruses come from a variety of unrelated lineages and consequently there is no taxon that unites all mosaic viruses Genomic map of a typical member of the genus Potyvirus. The virion is non-enveloped with a flexuous and filamentous nucleocapsid, 680 to 900 nanometers (nm) long and is 11-20 nm in diameter. The nucleocapsid contains ~2000 copies of the capsid protein. The symmetry of the nucleocapsid is helical with a pitch of 3.4 nm

popular ornamental crop in Taiwan and many other countries. Dasheen mosaic virus (DsMV) is the first potyvirus species reported to infect calla lilies. Besides DsMV, several potyviruses with distinct serological and molecular properties were isolated from calla lilies in Taiwan. In 2001, a potyvirus with serological and molecula Dasheen mosaic virus can be transmitted to healthy plants either by aphids or by vegetative propagation (6). Consequently, it is advisable to maintain a good insect control program and to exercise appropriate sanitation measures. Once a plant becomes infected it remains infected throughout its life. Heat treatments have not been successful in eliminating dasheen mosaic virus from infected.

Dasheen Mosaic Virus (DMV) mainly affects plants in the aroid family like Peace lilies, Philodendrons, and Monsteras.

The quick propagation of Dasheen clones (Xanthosoma spp) and (Colocasia esculenta L.) through biotechnical techniques has generated a great demand of free of diseases lines, especially to the Dasheen Mosaic Virus, this pathogen, belonging to the potivirus group, is the most important viral disease that affect the crop leading up to 40% of yield losses. The UM-ELISA diagnostic useded in massive. Mosaic Viruses. Simple Mosaic Symptoms -- Plants mottle in shades of light and dark green which is more evident in cool and cloudy weather as in the spring (Figure). There is no leaf wrinkling, no vine stunting, and no tuber defects. Pathogens are Potato Virus M (PVX), Potato Virus M (PVM) and Potato Virus S (PVS) and in combinations. Spread. In the present study a variation of RT-PCR involving previous virus immune precipitation (IP-RT-PCR) was used for identification of Dasheen mosaic virus (DMV), genus Potyvirus, in anthurium (Anthurium andraeanum), a promising ornamental produced in the State of Ceará, Brazil. Leaves and flowers from symptomatic plants exhibiting mosaic, chlorotic stripes along the foliar veins were collected. (Dasheen Mosaic Virus) Distorted leaves are often caused by the Dasheen mosaic virus. The virus is more common on select Dieffenbachia cultivars. Symptoms include distorted leaves and stunted plants. Aphids and man commonly help spread Dasheen mosaic virus. Today most pathogen-free Dieffenbachia stock is produced my tissue cultured micro-cuttings. No chemicals can control this virus disease.
