Abstract
- In April 2022, Aristolochia plants with symptoms of mosaic were observed in a garden at Jardim Botânico Plantarum, Nova Odessa, São Paulo State, Brazil. Potyviridae‐like particles were observed by transmission electron microscopy in leaf extracts. Total RNA extracted from symptomatic plants used in RT‐PCR with universal and BCMV‐specific primers detected the potyvirus bean common mosaic virus (BCMV). The cucumovirus cucumber mosaic virus (CMV) was identified only in Aristolochia littoralis plants that tested negative by RT‐PCR for BCMV. Phylogenetic analysis grouped samples of Aristolochia in a different clade among samples of Phaseolus vulgaris. Phylogenetic analysis indicated that the CMV isolate from Aristolochia belongs to the CMV group IA. BCMV was mechanically transmitted to healthy plants of A. fimbriata, Chenopodium quinoa, P. vulgaris cv. Jalo and Macroptilium lathyroides. CMV was mechanically transmitted to plants of A. fimbriata and C. quinoa. The BCMV and CMV were aphid transmitted only by Aphis gossypii to Aristolochia plants. This is the first report of BCMV and CMV infecting Aristolochia plants in Brazil. [ABSTRACT FROM AUTHOR]
