Abstract

The family includes the genus for three species of viruses with enveloped, rod-shaped virions. The monopartite, positive-sense ssRNA genome (26-27 kb) contains five canonical long open reading frames (ORFs). ORF1a encodes polyprotein pp1a containing proteinase domains. ORF1b is expressed as a large polyprotein pp1ab by ribosomal frameshifting from ORF1a and encodes replication enzymes. ORF2 encodes the nucleoprotein. ORF3 encodes two envelope glycoproteins. ORFX encodes a putative double membrane-spanning protein. Roniviruses infect shrimp but only yellow head virus is highly pathogenic. This is a summary of the International Committee on Taxonomy of Viruses (ICTV) Report on the family , which is available at ictv.global/report/roniviridae.

摘要

该科包括三个属的病毒，具有包膜的杆状病毒粒子。单分子、正链 ssRNA 基因组（26-27kb）包含五个规范的长开放阅读框（ORFs）。ORF1a 编码包含蛋白酶结构域的多蛋白 pp1a。ORF1b 通过从 ORF1a 核糖体移位而被表达为大的多蛋白 pp1ab，并编码复制酶。ORF2 编码核蛋白。ORF3 编码两种包膜糖蛋白。ORFX 编码一种假定的双膜跨膜蛋白。Roniviridae 科感染虾，但只有黄头病毒高度致病。这是病毒分类国际委员会（ICTV）关于 Roniviridae 科的报告摘要，可在 ictv.global/report/roniviridae 上获得。
