The concept of pathogen-derived resistance has been employed for the development of transgenic papaya… Management of this potyvirus is challenging, due to 1) its non-persistent transmission by numerous aphid species and 2) the diversity of PRSV strains that exists within a country or between different geographical regions.
Previously, it was known as Watermelon mosaic virus-1.However, tests using antisera showed that it was a strain of Papaya ringspot virus.The other strain is Papaya ringspot virus-P, which infects papaya and cucurbits (see Fact Sheet no. Global papaya production is severely affected by papaya ringspot disease caused by Papaya ringspot virus (PRSV). Free Online Library: Gene technology for papaya ringspot virus disease management. Papaya ringspot virus strain papaya (PRSV-P) is the main constraint in all papaya (Carica papaya L.) cultivating areas of the world. This review focuses on the development of PRSV resistant transgenic papaya through gene technology. The uncontrolled entry of seedlings or seed from uncertified sources should be prohibited. Papaya research at the Colegio de Postgraduados, Campus Veracruz, has focused on the development of integrated pest management tools for Papaya ringspot virus (PRSV-p), papaya mealybug and mites. Papaya ringspot virus (PRSV) infection is a global threat to papaya (Carica papaya L.) cultivation. Evidence suggests that transgene conferred PRSV resistance is mediated by RNA … The Integrated Management of Papaya … 194).Papaya ringspot virus-W does not infect papaya. Papaya (Carica papaya) is severely damaged by the papaya ringspot virus (PRSV). Papaya ringspot virus (PRSV) and Papaya leaf distortion mosaic virus (PLDMV), which causes disease symptoms similar to PRSV, threaten commercial production of both non-transgenic-papaya … A pot culture experiment was carried out to develop a recommendation for the management of papaya ringspot … Papaya Ring Spot Virus (PRSV) is one of the major obstacle for boosting papaya production in the country. (Report) by "The Scientific World Journal"; Biological sciences Environmental issues Host-virus relationships Genetic aspects Prevention Papaya …

Papaya ringspot virus - type P (PRSV-P) which infects papaya and cucurbits; Papaya ringspot virus … Papaya … The genetic diversity of PRSV depends upon geographical distribution and the influence of PRSV disease management on a sequence of PRSV isolates. Papaya ringspot disease is a type P (PRSV-P) virus that is devastating to papaya (or papaw) plants. Papaya (Carica papaya) is severely damaged by the papaya ringspot virus (PRSV). In fact, PRV-w causes major damage to cucurbits and was previously referred to as watermelon mosaic virus I. However, Papaya ringspot virus (PRSV), in the genus Potyvirus, was a potential limiting factor for growing papaya in Hawaii since the 1940s when PRSV was discovered on Oahu Island by D. D. Jensen (4), who coined the term "papaya ringspot virus… The former type infects both papaya and cucurbits while the latter type infects cucurbits but not papaya. Review Article Gene Technology for Papaya Ringspot Virus Disease Management Md.AbulKalamAzad, 1,2 LatifahAmin, 1 andNikMarzukiSidik 3 Centre for General Studies, Universiti Kebangsaan Malaysia … Papaya ringspot virus belongs to one of the largest and most economically important plant virus groups. The only successful option of managing PRSV-P infection via transgenic resistance is confined to Hawaii due to some technical and environmental issues; other viral management strategies have had limited success. Utilizing the concept of CP‐mediated resistance, transgenic papaya cultivars Rainbow and SunUp were developed and released in a timely manner to save Hawaii's papaya industry from damage caused by PRSV. The effect of rouging plants showing initial symptoms of papaya ringspot virus (PRSV-P) as a component of an integrated papayo management (MIP) system was quantified in Veracruz, Mexico. This review focuses on the development of PRSV resistant transgenic papaya through gene technology. Papaya ringspot potyvirus - type P is a major disease, and one that is difficult to control. Papaya ringspot (virus-W) Scientific Name. It was first found in South East Queensland in 1991. Papaya ringspot virus is grouped into two types, PRV-p and PRV-w. Papaya ringspot disease is caused by a plant virus called Papaya ringspot virus - type P (PRSV-P) which belongs to the genus Potyvirus in the family Potyviridae.. Two distinct types of Papaya ringspot virus are known:.
