The whitefly Bemisia tabaci is a major cosmopolitan pest and comprises complex of more than 36 cryptic species that cause serious damage to agricultural crops worldwide. In this study, the Mediterranean B. tabaci, formerly known as Q biotype, was identified for first time in Brazil.Adult were collected from different localities hosts Rio Grande do Sul, southernmost state country borders Uruguay Argentina. Partial sequencing mitochondrial cytochrome oxidase I (mtCOI) gene indicated MED...
The Bemisia tabaci is a polyphagous insect and successful vector of plant viruses. B. species complex in Brazil native from the New World (NW) group, as well invasive species, Middle East-Asia Minor 1 (MEAM1) Mediterranean (MED) were reported. For better understanding distribution different four years after invasion Brazil, whiteflies collected 237 locations throughout country between 2013 2017, identified facultative endosymbionts detected. survey revealed that MEAM1 was prevalent found on...
A proteomic analysis of the apoplastic fluid (APF) coffee leaves was conducted to investigate cellular processes associated with incompatible (resistant) and compatible (susceptible) Coffea arabica-Hemileia vastatrix interactions, during 24-96 hai period. The APF proteins were extracted by leaf vacuum infiltration protein profiles obtained 2-DE. comparative gels revealed 210 polypeptide spots whose volume changed in abundance between samples (control, resistant susceptible) identified...
Molecular and biological characterization of the begomovirus isolate BR:LNS2:Pas:01, obtained from yellow passionfruit plants in Livramento de Nossa Senhora, Bahia state, Brazil, was carried out. Sequence analysis demonstrated that BR:LNS2:Pas:01 DNA‐A had highest nucleotide sequence identity with Tomato chlorotic mottle virus (77%) five ORFs corresponding to genes cp, rep, trap, ren ac4 . The DNA‐B spot (74%) two mp nsp These values indicate this represents a new species, for which name...
Grapevine leafroll-associated virus 3 (GLRaV-3), the main viral species of grapevine leafroll complex, causes yield and quality reduction in grapes (Vitis spp.). The coat protein gene was RT-PCR-amplified from total RNA extracted infected leaves amplified fragment cloned completely sequenced. subsequently subcloned into pRSET-C expression vector. recombinant plasmid used to transform Escherichia coli BL21:DE3 express capsid protein. protein, fused a 6 His-tag, purified by affinity...
Jangada Brava (a local name) (Heliocarpus americanus L.) is a dioecious plant, native to South America, that can reach 12 m in height and 50 cm diameter. It be found the semideciduous broadleaved forest of Parana Basin (Lorenzi 1992). Its wood used manufacture pencils, toys, cross laminated timber (CLT). The tree planted as quick replenishment for degraded areas due its good growth. In January 2017, seeds collected directly from trees around neighborhood city Engenheiro Beltrao, Parana,...
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...
