“…The same approach was applied to ORF2, in which BLASTp alignments showed higher scores with RT proteins from PVCV ( e-value = 1e-173) [ 15 ], CitPRV ( e-value = 1e-149) [ 16 ], CaMV ( e-value = 2e-90) [ 21 ], CERV ( e-value = 8e-83) [ 12 ] and FMV ( e-value = 2e-86) [ 17 ]. Multiple alignments showed a 73%, 56%, 38% and 37% identity with PVCV, CitPRV, CaMV and FMV, respectively.…”

“…RT is a key element in retrotransposons, retroviruses, group II introns, bacterial multi-copy single-stranded DNA (msDNA), hepadnaviruses, and Caulimoviruses. RT catalyzes DNA replication from an RNA template, and is responsible for the replication of retroelements [ 21 ].…”

“…RNase H is an endonuclease that cleaves the RNA strand of RNA/DNA hybrid in a sequence nonspecific manner. This characteristic is widely present in various organisms and it is clearly important for its relation with the origins of viruses [ 21 ]. The conserved amino acids Asp, Glu, Asp, His (H) and Asp are known to be related to the catalytic region of the protein ( Figure 1 C).…”

Here, we report the genome sequence and evidence for transcriptional activity of a virus-like element in the native Chilean berry tree Aristotelia chilensis. We propose to name the endogenous sequence as Aristotelia chilensis Virus 1 (AcV1). High-throughput sequencing of the genome of this tree uncovered an endogenous viral element, with a size of 7122 bp, corresponding to the complete genome of AcV1. Its sequence contains three open reading frames (ORFs): ORFs 1 and 2 shares 66%–73% amino acid similarity with members of the Caulimoviridae virus family, especially the Petunia vein clearing virus (PVCV), Petuvirus genus. ORF1 encodes a movement protein (MP); ORF2 a Reverse Transcriptase (RT) and a Ribonuclease H (RNase H) domain; and ORF3 showed no amino acid sequence similarity with any other known virus proteins. Analogous to other known endogenous pararetrovirus sequences (EPRVs), AcV1 is integrated in the genome of Maqui Berry and showed low viral transcriptional activity, which was detected by deep sequencing technology (DNA and RNA-seq). Phylogenetic analysis of AcV1 and other pararetroviruses revealed a closer resemblance with Petuvirus. Overall, our data suggests that AcV1 could be a new member of Caulimoviridae family, genus Petuvirus, and the first evidence of this kind of virus in a fruit plant.

“…Transmission by other vector type or by pollen has never been reported in nature, but CaMV can be readily transmitted mechanically to a host plant [ 23 ]. Members of the Brassicaceae have been reported as systemic hosts, but B29, W260, Japan-S, and NY8153 CaMV isolates are able to infect also Solanaceae species Nicotiana clevelandii and Datura stramonium [ 24 ], [ 25 ]. CaMV probably spread from a single population around 400–500 years ago and is known in four geographically distributed lineages [ 26 ].…”

Platinum Anniversary: Virus and Lichen Alga Together More than 70 Years

Trebouxia aggregata (Archibald) Gärtner (phylum Chlorophyta, family Trebouxiaceae), a lichen symbiotic alga, has been identified as host of the well-known herbaceous plant virus Cauliflower mosaic virus (CaMV, family Caulimoviridae). The alga had been isolated from Xanthoria parietina more than 70 years ago and has been maintained in a collection since that time. The CaMV detected in this collection entry has now been completely sequenced. The virus from T. aggregata is mechanically transmissible to a herbaceous host and induces disease symptoms there. Its genome differs by 173 nt from the closest European CaMV-D/H isolate from cauliflower. No site under positive selection was found on the CaMV genome from T. aggregata. We therefore assume that the virus’s presence in this alga was not sufficiently long to fix any specific changes in its genome. Apart from this symbiotic alga, CaMV capsid protein sequences were amplified from many other non-symbiotic algae species maintained in a collection (e.g., Oonephris obesa, Elliptochloris sp., Microthamnion kuetzingianum, Chlorella vulgaris, Pseudococcomyxa sp.). CaMV-free Chlorella vulgaris was treated with CaMV to establish virus infection. The virus was still detected there after five passages. The virus infection is morphologically symptomless on Chlorella algae and the photosynthesis activity is slightly decreased in comparison to CaMV-free alga culture. This is the first proof as to the natural presence of CaMV in algae and the first demonstration of algae being artificially infected with this virus.
