Complete genome sequence of a novel partitivirus from a wild brassicaceous plant, Arabidopsis halleri.

Two contigs with high similarity to partitivirus sequences were identified by de novo assembly of sequences obtained by RNA-Seq from a wild brassicaceous plant, Arabidopsis halleri subsp. gemmifera. Here, we report the complete genome sequence of a putative novel partitivirus. Excluding the poly-A tail, it consists of two RNA genome segments of 1912 and 1769 bp, which are predicted to encode a 585-amino-acid-long putative RNA-dependent RNA polymerase (RdRp) and a 487-amino-acid-long putative capsid protein (CP), respectively. Phylogenetically, this virus belongs to the genus Alphapartitivirus and is most closely related to Raphanus sativus partitivirus 1 from radish. We propose the name "Arabidopsis halleri partitivirus 1" (AhPV1) for this novel virus.
