摘要： Viral diseases pose a threat to fruit tree growth. In this study, we observed some pimple-shaped 'Yali' pears (Pyrus bretschneideri Rehd.) and investigated their viral components. We used virome analysis to elucidate the viral composition within the pimple-shaped fruit. RT-PCR was applied to detect the plant viruses of fruits, leaves, and branches in 'Yali' pear. We also constructed a phylogenetic tree based on the amino acid sequences of the movement proteins of 6 apple stem grooving virus (ASGV) isolates and 44 ASGVs from the NCBI database. We detected ASGV and apple stem pitting virus (ASPV) in the pimple-shaped pear fruits, which is the first report of these viruses existing in 'Yali' pear fruits. ASGV was present in all pimple-shaped fruit samples from six 'Yali' pear-producing regions. The phylogenetic tree showed that ASGVs from pears, apples, and citrus plants were separated into different branches, suggesting that hosts influence the genetic diversity of ASGV. Our study revealed the viral components and genetic variation of ASGV in pimple-shaped pear fruit, providing new insights into the epidemiology of this virus.
