Endogenous pararetroviruses (EPRVs) are characterized in several plant genomes and their biological effects have been reported. In this study, hundreds of EPRV segments were identified in six Citrinae genomes. A total of 1034 EPRV segments were identified in the genomes of sweet orange, 2036 in pummelo, 598 in clementine mandarin, 752 in Ichang papeda, 2060 in citron and 245 in atalantia. Genomic analysis indicated that EPRV segments tend to cluster as hot spots in the genomes, particularly on chromosome 2 and 5. Large numbers of simple repeats and transposable elements were identified in the 2-kb flanking regions of the EPRV segments. Comparative genomic analysis and PCR experiments showed that there are highly conserved EPRV segments and species-specific EPRV segments between the Citrinae genomes. Phylogenetic analysis suggested that the integration events of EPRVs could initiate in a common progenitor of Citrinae species and repeatedly occur during the Citrinae divergence.
