  abstract = {{R}ice yellow mottle virus ({RYMV}) causes the most important rice disease in {A}frica. {RYMV} belongs to the genus {S}obemovirus. {RYMV} has icosahedral particles of 25 nm in diameter. {T}he virions contain a single coat protein ({CP}) of 29 k{D}a, a genomic {RNA}, and one subgenomic {RNA} molecule. {T}he genomic {RNA} is one single-stranded messenger-sense molecule, 4450 nt in size. {T}he 5′ terminus of the {RNA}s has a genome-linked protein ({VP}g), and lacks a poly({A}) tail. {RYMV} often encapsidates, in addition to its genomic {RNA}, a viroid-like satellite {RNA}. {T}he {RYMV} genome is organized in four overlapping open reading frames ({ORF}s). {T}he {ORF}1 encodes a protein {P}1 required for cell-to-cell movement of the virus. {P}1 is a suppressor of posttranslational gene silencing. {T}he {ORF}2a contains sequence motifs for the proteinase and the {VP}g. {T}he {ORF}2b encodes the {RNA}-dependent {RNA} polymerase. {T}he {ORF}4 is translated from the subgenomic {RNA} and encodes the {CP}. {T}he natural host range of {RYMV} is restricted to a few members of the {P}oaceae family. {T}ransmission is due to chrysomelidae vectors and to contact during cultural practices. {T}he more efficient resistance called high resistance encodes the translation initiation factor e{IF}(iso)4{G}. {T}his resistance is overcome by a point mutation in the {VP}g. {T}he evolution of {RYMV} has been inferred from its genetic diversity.},
