Contrasting genetic structure between two begomoviruses infecting the same legu...
Xavier, César Augusto Diniz; Pereira, Hermano Monteiro de Barros; Lima, Gaus Silvestre de Andrade; Assunção, Iraı́ldes PereiraBegomoviruses are whitefly-transmitted, ssDNA plant viruses and are among the most damaging pathogens causing epidemics in economically important crops worldwide. Wild/non-cultivated plants play a crucial epidemiological role, acting as begomovirus reservoirs and as ‘mixing vessels’ where recombination can occur. Previous work suggests a higher degree of genetic variability in begomovirus populations from non-c...
The diversification of begomovirus populations is predominantly driven by mutat...
Lima, Alison T. M.; Silva, Jose ́ C. F.; Silva, Fábio N.; Castillo-Urquiza, Gloria P.; Silva, Fabyano F.; Seah, Yee M.; Mizubuti, Eduardo S. G.Begomoviruses (single-stranded DNA plant viruses) are responsible for serious agricultural threats. Begomovirus populations exhibit a high degree of within-host genetic variation and evolve as quickly as RNA viruses. Although the recombination-prone nature of begomoviruses has been extensively demonstrated, the relative contribution of recombination and mutation to the genetic variation of begomovirus populatio...
Synonymous site variation due to recombination explains higher genetic variabil...
Lima, Alison T. M.; Sobrinho, Roberto R.; González-Aguilera, Jorge; Rocha, Carolina S.; Silva, Sarah J. C.; Xavier, César A. D.; Silva, Fábio N.Begomoviruses are ssDNA plant viruses that cause serious epidemics in economically important crops worldwide. Non-cultivated plants also harbour many begomoviruses, and it is believed that these hosts may act as reservoirs and as mixing vessels where recombination may occur. Begomoviruses are notoriously recombination-prone, and also display nucleotide substitution rates equivalent to those of RNA viruses. In B...
