Summary. The complete nucleotide sequence of Bean yellow mosaic virus
(BYMV) gladiolus isolate GDD was determined and compared to broad bean
isolates BYMV-MB4 and BYMV-S. The BYMV-GDD genome (9528 nt) was
more similar to BYMV-MB4 (9532 nt) than to BYMV-S (9547 nt), which has
“atypical” symptom expression and host range. The greatest variability occurred
in the 5
untranslated region, P1 protein, and NIa-VPg protein, the N-terminal
two thirds of HC-Pro, and the C-terminal one third of P3. Each of these regions
has been correlated with symptom or host differences between isolates of other
potyviruses, and may contribute to the “atypical” nature of BYMV-S.
Bean yellow mosaic virus (BYMV) infects a broad range of plants, including
ﬁeld legumes such as beans, peas, lupins, and clover, and both monocotyledonous
and dicotyledonous ornamental crops such as gladiolus, bulbous iris, lisianthus,
gentian, and some orchids. BYMV has also been isolated from several types of
trees, including beech (Fagus) . Several other potyviruses infecting legumes
(Clover yellow vein virus, ClYVV; Pea mosaic virus, PMV; White lupin mosaic
virus, WLMV; and Sweet pea mosaic virus, SPMV) are all members of the BYMV
subgroup, and PMV and WLMV are now recognized as strains of BYMV .
Some isolates of BYMV have been distinguished serologically using a panel of
monoclonal antibodies, which have speciﬁcities that vary from recognition of
Nucleotide sequence data reported are available in the DDBJ/EMBL/GenBank database
under the accession number AY192568.
