Begomoviruses can be found in association with alphasatellites, which are capable of autonomous replication but dependent on the helper begomovirus for systemic infection, encapsidation and vector transmission. Previous studies suggest that presence NW alphasatellites (genus Clecrusatellite) is associated more severe symptoms. To better understand this interaction, we investigated effects two infectivity, symptom development, viral DNA accumulation transmission three begomoviruses hosts. In...
Abstract African oil palm ( Elaeis guineensis Jacq.) is considered the most productive oleaginous crop due to its high production per hectare. In April 2015, E. leaves showing elliptical necrotic spots with yellowish halo were observed in a commercial plantation Moju, Pará state, Brazil. A synematous fungus was consistently associated spots. The aim of this study identify Based on morphology and DNA sequence data internal transcribed spacer rDNA, identified as Helminthosporiella stilbacea ....
Begomoviruses (single-stranded DNA plant viruses transmitted by whiteflies) are economically important pathogens causing epidemics worldwide. Tomato-infecting begomoviruses emerged in Brazil the 1990's following introduction of Bemisia tabaci Middle East-Asia Minor 1. It is believed that these evolved from indigenous infecting non-cultivated hosts. However, tomato-infecting rarely found hosts, and vice-versa. possible viral populations a given host composed primarily which well adapted to...
Tomato interveinal chlorosis virus (ToICV; Begomovirus solanumintervenae, genus Begomovirus, family Geminiviridae) has been described infecting tomato (Solanum lycopersicum) and Macroptilium lathyroides in Northeastern (NE) Brazil for more than a decade (Albuquerque et al., 2012; Silva 2012). During survey 2020, plants of the leguminous weed Rhynchosia minima exhibiting virus-like symptoms such as mosaic were observed state Alagoas, NE Brazil. Symptomatic leaf samples R. randomly collected...
Mixed infection between two or more begomoviruses is commonly found in tomato fields and can affect disease outcomes by increasing symptom severity viral accumulation compared with single infection. Viruses that include severe rugose virus (ToSRV) mosaic (ToRMV). Previous work showed mixed infection, ToRMV negatively affects the infectivity of ToSRV. ToSRV share a high degree sequence identity, including cis-elements common region (CR) their specific recognition sites (iteron-related domain,...
