摘  要:
水稻条纹病毒(Rice stripe virus,RSV)的外壳蛋白(coat protein,CP)参与病毒转录、复制等多个生物学过程。病毒蛋白之间的互作对病毒侵染活性非常重要,在明确RSV外壳蛋白CP能够自身互作的基础上,通过构建CP蛋白N端、M区段和C端(CP-N、CP-M和CP-C)的酵母表达载体,利用酵母双杂交系统确定外壳蛋白CP自身互作的活性区段。结果表明,N端和C端第1~81个氨基酸是参与水稻条纹病毒CP蛋白自身互作的活性区段。这一研究结果不仅有助于加深理解RSV CP蛋白在病毒基因组稳定、复制过程中的作用,也有助于加深了解RSV、寄主和传播介体之间关系。

摘  要:
Coat protein of Rice stripe virus plays important roles in several biological processes,such as viral transcription and replication.Interactions among viral proteins are essential for viral infection activity on host and insect vectors.In the present study,yeast two-hybrid system was used to detect the functional region inolving in the self-interaction of the RSV coat protein(CP).It was revealed that N-and C-terminal 81 amino acid residues played an essential role in self-interaction of RSV CP.Our results will be contributed to better understanding not only for functions of CP on viral stabilization and replication in insect vectors or host plants,but also for the relationship among virus,insect vectors and host plants.
