A positive-sense single-stranded RNA mycovirus was isolated from Morchella sextelata strain ZY-1 and designated as "Morchella sextelata endornavirus 1" (MsEV1). The complete genome of MsEV1 was found to be 16,589 nucleotides (nt) in length and to contain a single large open reading frame (ORF) encoding the viral proteins PRK00409, transmethylase, DEXDc, helicase, and RdRP in a polyprotein of 5,477 amino acids. Phylogenetic analysis based on RdRP nucleotide sequences revealed that this endornavirus is a member of the genus Betaendornavirus in the family Endornaviridae.
从六棱羊肚菌菌株ZY-1中分离出一种正义单链RNA真菌病毒，并将其命名为“六棱羊肚菌内病毒1”（MsEV1）。发现MsEV1的完整基因组长度为16589个核苷酸（nt），并包含一个单一的大开放阅读框（ORF），该阅读框在一个由5477个氨基酸组成的多蛋白中编码病毒蛋白PRK00409、甲基转移酶、DEXDc、解旋酶和RNA依赖的RNA聚合酶（RdRP）。基于RdRP核苷酸序列的系统发育分析表明，这种内病毒是内病毒科β内病毒属的成员。
