Phylodynamics of sunflower chlorotic mottle virus, an emerging pathosystem
Distribution and epidemiological patterns of sunflower chlorotic mottle virus (SCMoV) in sunflower (Helianthus annuus L.) growing areas in Argentina were studied from 2006 to 2017. The virus was detected exclusively in the Pampas region (Entre Ríos, Santa Fe, Córdoba, La Pampa and Buenos Aires pro...

| Sumario: | Distribution and epidemiological patterns of sunflower chlorotic mottle virus (SCMoV) in sunflower (Helianthus
annuus L.) growing areas in Argentina were studied from 2006 to 2017. The virus was detected exclusively in the
Pampas region (Entre Ríos, Santa Fe, Córdoba, La Pampa and Buenos Aires provinces). Phylodynamic analyses
performed using the coat protein gene of SCMoV isolates from sunflower and weeds dated the most recent
common ancestor (MRCA) back to 1887 (HPD95% = 1572–1971), which coincides with the dates of sunflower
introduction in Argentina. The MRCA was located in the south of Buenos Aires province and was associated with
sunflower host (posterior probability for the ancestral host, ppah = 0.98). The Bayesian phylodynamic analyses
revealed the dispersal patterns of SCMoV, suggesting a link between natural host diversity, crop displacement by
human activities and virus spread. |
