title: Sequence comparisons of medium RNA segment among 15 California serogroup viruses.
abstract: The complete nucleotide sequences have been determined for the M segment of 12 California (CAL) serogroup bunyaviruses. A method is described here of long reverse transcription-polymerase chain reaction (RT-PCR) that yields the full-length medium (M) RNA genomic segment. A phylogenetic tree was constructed by comparison of the open reading frames (ORFs) in the M RNA segment of 15 CAL serogroup viruses. Three distinct branches were identified and they are represented by the California encephalitis (CE), Melao (MEL), and Trivittatus (TVT) complexes. These groups correspond to those previously established by small (S) RNA genomic sequences. In addition, except for Inkoo virus, the predicted relationship among these viruses agreed with those found by serology.
