摘要： Xinjiang wild apricot（Prunus armeniaca） has strong resistance to drought and cold. It is an important genetic resource for breeding. In 2021, twenty leaf samples of Xinjiang wild apricot were collected in the wild forests of Tianshan Mountain in Yili, Xinjiang. Using the high-throughput sequencing and RT-PCR, peach chlorotic leaf spot virus（PCLSV） and mume-associated luteovirus（Ma LV） were identified. Whole genomes of these two viruses were obtained by RT-PCR and RACE.After removing poly（A）, the genome of PCLSV from Prunus armeniaca（PCLSV-YX） contains 7 462 nucleotides（nts） with three overlapping open reading frames（ORFs）. The genome of MaLV from Prunus armeniaca（MaLV-YX） contains 5 753 nts, and has six ORFs. Phylogenetic analysis showed that PCLSV-YX was closely related to isolates of ‘PR19-2’ and ‘TaTao’. MaLV-YX was closely related to cherry-associated luteovirus（ChALV）, Prunus mahaleb-associated luteovirus（PmALV）, peach-associated luteovirus（PaLV） and peach-associated luteovirus 2（PaLV 2）.
