Plants of Capsicum annuum cv. Magali R, resistant to Pepper yellow mosaic virus (PepYMV), which showed severe yellow mosaic, leaf malformation and stunting were observed during the 2003/04 growing season in Lins, São Paulo State, Brazil. Potyvirus-like particles observed in leaf sap from infected plants under the electron microscope reacted with an antiserum against PepYMV in PTA-ELISA. In addition to C. annuum cv. Magali R, this potyvirus also infected systemically the resistant C. annuum cv. Rubia R. The nucleotide sequence of part of the CP gene of this potyvirus shared 96-98% identity with that of other PepYMV isolates. The partial nucleotide sequence of the 3' NTR showed 94-96% identity with that of PepYMV. These data indicate that this potyvirus is a resistance-breaking isolate of PepYMV.

Macroptilium Lathyroides

The leguminous weed Macroptilium lathyroides is considered a potential host of the Bean golden yellow mosaic virus (BGYMV; BGMV = Mesoamerican isolates). To determine if M. lathyroides could be a host for BGYMV, an infectivity cycle was established between this weed and Phaseolus vulgaris. Virus transmission was carried out using the whitefly, Bemisia argentifolli, as a vector. Inoculated plants of both species were examined for symptoms such as mosaic, stunting, and leaf distortion. P. vulgaris and M. lathyroides showed golden yellow mosaic symptoms during all infectivity cycle stages. Symptomatic plants of both species were tested for BGYMV using polymerase chain reaction (PCR) and nucleotide sequence analysis. Two degenerate primers sets were used for PCR to detect viral DNA: PAL1v1978/PAR1c715 and PCRc2/PBL12039. PCR analysis using primers PCRc2/PBL12039 amplified viral DNA for component B from both plant species. Nucleotide sequence analysis revealed a 93% identity between the virus isolated from M. lathyroides and the Puerto Rican isolate of BGYMV. These results confirmed that M. lathyroides could serve as an alternative host of BGYMV and that an infectivity cycle of BGYMV could possibly occur between P. vulgaris and M. lathyroides in Puerto Rico.
