Molecular characterization of a citrus yellow vein clearing virus strain from China.
The complete nucleotide sequence of an isolate of citrus yellow vein clearing virus from Yunnan, China (CYVCV-RL), was determined following whole-genome amplification by RT-PCR. The CYVCV-RL genome was 7529 nt in length, excluding the 3' poly (A) tail, and contained six open reading frames (ORFs), resembling that of viruses belonging to the genus Mandarivirus in the family Alphaflexiviridae. Sequence analysis showed that the CYVCV-RL shared the greatest nucleotide sequence identity with the CYVCV-Y1 (JX040635) isolate from Turkey for the whole genome (97.1%), 5' UTR (98.7%), 3' UTR (100.0%), and each of six ORFs (96.5% to 97.8%), suggesting that there is apparent genetic stability among CYVCV isolates of different geographic origin.
