猪繁殖与呼吸综合征病毒ORF5a/ORF5重叠区的分离
THE SEPERATION OF ORF5A/ORF5 OVERLAPPING GENES OF PORCINE REPRODUCTIVE AND RESPIRATORY SYNDROME VIRVS
摘要
Abstract
For the first time,a new chimeric Porcine reproductire and respiratory syndrome virus(PRRSV) was constructed by replacing ORF2-5a of the full-length infectious cDNA clone pARRSasc(type 2) with their corresponding counterparts of the clone pSHE(type 1).This study was designed to(1) make ORF5a independent of ORF5;(2) dissertate the structure and function of 5a protein;(3) elucidate the structure-function relationship of inter-genotypic PRRSV structural proteins.The results showed that ORF2-5a of PRRSV type 1 was stable and expressed structural proteins and played full functions in the backbone type 2 virus.The construction of the chimeric PRRSV expressing ORF5a independent of ORF5 has laid foundation to better understand the structure and function of 5a protein.关键词
