Resumo

Coffee ringspot virus (CoRSV) belongs to the Dichorhavirus genus and has been considered the causal agent of the emergent disease in commercial coffee orchards. The virus is commonly transmitted by Brevipalpus papayensis Baker (Acari: Tenuipalpidae) in a persistent propagative mode, however B. yothersi is another mite vector. Here, we report for the first time that the common succulent panda plant (Kalanchoe tomentosa Baker) and bear's paw (Cotyledon tomentosa Harv.) can be infected with CoRSV transmitted by viruliferous B. papayensis females. Leaves showed typical symptoms of chlorotic and necrotic spots seven days after inoculation and RT-PCR confirmed the presence of CoRSV in symptomatic tissues. Amplicon sequences showed > 97% identity with a known CoRSV sequence (Genbank accession number GQ979998). In addition, transmission electron microscopy revealed the presence of typical dichorhavirus particles in the nucleus of symptomatic tissues of panda plants. Thus, considering the relevance of succulents in the ornamental market and the emergent CoRSV, it is important to provide information about the effects of this virus in different hosts. (AU)
