“…Two distinct lineages of the virus are widespread in Europe, and one of them is also in Japan (Kirino et al, 2008) and in the Kosciusko alpine area of south-eastern Australia (Guy & Gibbs, 1981). CP gene sequences of the three populations (Blok et al, 1987;Hayden et al, 1998;Kirino et al, 2008) form separate clusters that are approximately equidistant (0.063-0.078 ns per site in trees calculated as in Fig.…”

Recent research has revealed that some plant viruses, like many animal viruses, have measurably evolving populations. Most of these viruses have single-stranded positive-sense RNA genomes, but a few have single-stranded DNA genomes. The studies show that extant populations of these viral species are only decades to centuries old. The genera in which they are placed have diverged since agriculture was invented and spread around the world during the Holocene period. We suggest that this is not mere coincidence but evidence that the conditions generated by agriculture during this era have favoured particular viruses. There is also evidence, albeit less certain, that some plant viruses, including a few shown to have measurably evolving populations, have much more ancient origins. We discuss the possible reasons for this clear discordance between short-and long-term evolutionary rate estimates and how it might result from a large timescale dependence of the evolutionary rates. We also discuss briefly why it is useful to know the rates of evolution of plant viruses.

“…Several members are also pathogens of economically important crops. For instance, the type member turnip yellow mosaic virus (TYMV) infects diverse Brassica plants in Eurasia and Australia [ 6 , 7 ]. Another example is tomato blistering mosaic virus (TBMV), an emerging threat to tomato and tobacco production in South America [ 8 , 9 ].…”

Leaves of hollyhock (Alcea rosea) exhibiting vein chlorosis and yellow mosaic symptoms were collected at public sites in Lausanne and Nyon, two cities of western Switzerland. Diagnostic methods untangled in samples from both sites the mixed infections of a novel isometric virus, tentatively named “Alcea yellow mosaic virus” (AYMV) with the carlavirus Gaillardia latent virus. A new potyvirus was also identified in samples from Nyon. A combination of Illumina, Nanopore and Sanger sequencing was necessary to assemble the full-length genome of AYMV, revealing an exceptionally high cytidine content and other features typically associated with members of the genus Tymovirus. The host range of AYMV was found to be restricted to mallows, including ornamentals as well as economically important plants. Phylogenetic analyses further showed that AYMV belongs to a Tymovirus subclade that also gathers the other mallow-infecting members. The virus was readily transmitted by sap inoculation, and the weevil species Aspidapion radiolus was evidenced as a vector. Transmission assays using another weevil or other insect species did not succeed, and seed transmission was not observed.
