摘要: Proviral DNA was extracted from donkey leukocyte infected with Chinese donkey leukocyte attenuated equine infectious anemia virus (DLA-EIAV), and peripheral blood lymphocytes (PBL) from a horse infected with the virulent EIAV strain Liaoning (ElAV L). The entire proviral DNA from both viruses was cloned and sequenced. The lengths of complete genomic sequences of DLA-EIAV and EIAV L provirus were 8266 bp and 8235 bp, respectively. Sequence comparison indicated that DLA-EIAV shares 97.0% and 97.5% in sequence homology with EIAV L and donkey-adapted EIAV (DA-EIAV), respectively. Lots of variations occurred in long terminal repeat (LTR, consisting of U3, R, U5), ORF S2, and env regions between DLA-EIAV and EIAV L. The nucleotide sequence differences of the two viruses in U3, R, U5, ORF S2, and env are 13.2%, 7.5%, 5.1%, 3.9%, and 2.7%, respectively, and predicted amino acid sequence differences in env and S2 coding regions are 4.4% and 8.8%, respectively. Six conserved regions are characterized in Gp90. There is a cis-activating GATA motif in ENH of DLA-EIAV and EIAV L. Two Winked glycosylation sites disappeared in DLA-EIAV Gp90 in comparison with that of EIAV L. A bHLH transcription factor binding consensus sequence was found in LTR of DLA-EIAV but not in EIAV L. Furthermore, there is a mutation in the stem of DLA-EIAV TAR resulting in formation of a uridine tuber. Further study is needed to uncover the relationship between sequence changes and their biological functions of DLA-EIAV and L.
