The ''Potyviridae'' are a family of viruses that encompasses more than 30% of known plant viruses,〔Riechmann JL, Lain S, Garcia JA (1992) Highlights and prospects of potyvirus molecularbiology. J Gen Virol 73:1–16.〕〔Berger PH, et al. (2005) in Virus Taxonomy: Eighth Report of the InternationalCommittee on the Taxonomy of Viruses, eds Fauquet CM, Mayo MA, Maniloff J,Desselberger U, Ball LA (Elsevier Academic, San Diego), pp 819–841.〕 many of which are of great agricultural significance. Currently, 190 species are placed in this family, divided among eight genera.〔(【引用サイトリンク】url=http://viralzone.expasy.org/all_by_species/48.html )〕〔(【引用サイトリンク】title=Virus Taxonomy: 2014 Release )〕 ==Taxonomy== Based on the amino acid sequences of their coat proteins, potyviruses are now divided into eight genera. All but the ''Bymovirus'' genus are single-stranded particles. Group: ssRNA(+) }}〔 ''Potyvirus'' is the largest genus in the family, with more than 100 known species.〔Description of Plant Viruses: (Potyviridae family )〕 These viruses are 720-850 nm in length and are transmitted by aphids. They can also be easily transmitted by mechanical means. The species in the genus ''Macluravirus'' are 650–675 nm in length and are also transmitted by aphids. The plant viruses in the genus ''Ipomovirus'' are transmitted by whiteflies and they are 750–950 nm long. ''Tritimovirus'' and the ''Rymovirus'' viruses are 680–750 nm long and are transmitted by (eriophydid mites ). (The rymoviruses are closely related to the potyviruses and may eventually be merged with the potyviruses.〔Description of Plant Viruses: (Potyviridae family Figure )〕) The ''Bymovirus'' genome consists of two particles instead of one (275 and 550 nm) and these viruses are transmitted by the chytrid fungus, ''Polymyxa graminis''. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Potyviridae」の詳細全文を読む スポンサード リンク
