Genome characterization of citrus yellow vein-clearing virus: limited heterogeneity of viral genomes in Mandarivirus-infecting different citrus species.

ABSTRACT: Citrus yellow vein-clearing virus (CYVCV) is a mandarivirus infecting citrus producing yellow vein-clearing symptoms. The leaf samples collected during surveys of different citrus-growing areas in India exhibited diverse symptoms and 40% of the plants were positive for CYVCV in RT-PCR, indicating the wide distribution of the virus in India. It was reported for first time that CYVCV infects kinnow mandarin and sweet oranges and produces chlorotic ringspots symptoms identical to Indian citrus ringspot virus (ICRSV). The complete genome sequences of CYVCV infecting four citrus cultivars have been deciphered through overlapping primers. All the four genomes comprise of 7531 nucleotides excluding the 3' poly (A) tail. The sequence identity of genomes of four CYVCV isolates in the present study
