title: The complete nucleotide sequence and its organization of the genome of Barley yellow dwarf virus-GAV.
abstract: The complete nucleotide sequence of genomic RNA of BYDV-GAV was determined. It comprised 5685 nucleotides and contained six open reading frames and four un-translated regions. The size and organization of BYDV-GAV genome were similar to those of BYDV PAV-aus. The nucleotide and deduced amino acid sequences of the six ORFs were aligned and compared with those of other luteoviruses. The results showed that there was a high degree of identity between BYDV-GAV and MAV-PS1 in all ORFs except ORF5 and ORF6, which had only 87.4% and 70.2% identities respectively. The reported genomic nucleotide sequence of MAV was shorter than that of BYDV-GAV, but the comparison of the genomic nucleotide sequences for MAV-PS1 and GAV showed 90.4% sequence identity for the same region of the genome. According to the level of sequence similarities, BYDV-GAV should be closely related to BYDV-MAV.
