THE COMPLETE NUCLEOTIDE SEQUENCE AND GENOME ORGANIZATION OF TOMATO INFECTIOUS CHLOROSIS VIRUS: A DISTINCT CRINIVIRUS MOST CLOSELY RELATED TO LETTUCE INFECTIOUS YELLOWS VIRUS. Phytopathology 99: S142.
Technical Abstract: Tomato infectious chlorosis virus (TICV), affects tomato production in many temperate to subtropical parts of the world where production is impacted by the presence of the greenhouse whitefly (Trialeurodes vaporariorum). Symptoms include interveinal yellowing, and leaves become thickened and crispy, breaking easily when bent. Yield is affected through decreased fruit size and number, as well as decreased plant longevity. The complete nucleotide sequence of TICV was determined and compared with other members of the genus Crinivirus. RNA 1 is 8271 nucleotides long with three open reading frames and encodes proteins involved in replication. RNA 2 is 7913 nucleotides long and encodes eight proteins common within the genus Crinivirus involved in genome protection, movement, and other functions yet to be identified. Similarity between TICV and other criniviruses varies throughout the genome, but TICV is related more closely to Lettuce infectious yellows virus than to any other crinivirus. With the addition of TICV, phylogenetic comparisons among criniviruses indicates that the genus could appropriately be separated into three distinct groups.
