In 2022, virus‐like symptoms were observed in Adenium obesum plants in Brazil. High‐throughput sequencing analysis found three contig sequences of cucumber mosaic virus (CMV) genome segments, which were of 3352, 3006 and 2221 nucleotides, and shared 98.59%, 95.02% and 98.05% nucleotide identities with the nucleotide sequences of CMV RNAs 1, 2 and 3, respectively. Phylogenetic analysis of the coat protein gene indicated that the CMV isolate belongs to the subgroup IB. Symptoms of mottle like those observed in the field samples were reproduced on mechanically inoculated plants of A. obesum, and RT‐PCR confirmed the CMV infection. CMV was transmitted by Aphis gossypii to A. obesum plants. This is the first report of CMV infecting A. obesum plants in Brazil. [ABSTRACT FROM AUTHOR] |
