Increase of tospoviral diversity in Brazil with the identification of two new tospovirus species, one from chrysanthemum and one from zucchini.
ABSTRACT During a survey conducted in several different regions of Brazil, two unique tospoviruses were isolated and characterized, one from chrysanthemum and the other from zucchini. The
Tissue tropism related to vector competence of Frankliniella occidentalis for tomato spotted wilt tospovirus.
TLDR
The results show that the establishment of TSWV infection in the various tissues and the potential of transmission seems to be regulated by different barriers and processes related to the metamorphosis of thrips.
The competence of four thrips species to transmit and replicate four tospoviruses
TLDR
Results strongly suggest that competence to transmit is regulated not only by the initial amount of virus acquired and replication, but also by possible barriers to virus circulation inside the thrip's body.
Sequence diversity of NSM movement protein of tospoviruses
TLDR
The sequence information obtained in this work would facilitate functional analysis of NSM during the tospovirus infection process, and reflect the geographical prevalence and phylogenetic analysis of N and NSM proteins.
Detection of three Allexivirus species infecting garlic in Brazil
TLDR
In this study, garlic samples collected in three geographical areas of Brazil were tested by Dot-ELISA for the detection of allexiviruses using monoclonal specific antibodies to detect Garlic virus A (GarV-A), Gar garlic virus B ( GarV-B),Garlic virus C (Gar V-C) and a polyclonal antiserum able to detect the three virus species mentioned plus Garlicirus D (Garv-D).
The Identification of the Vector Species of Iris Yellow Spot Tospovirus Occurring on Onion in Brazil.
TLDR
Three thrips species, Thrips tabaci, Frankliniella schultzei, and F. occidentalis, that are major vegetable and floral crop pests in the Federal District, Brazil, were tested for their ability to transmit the IYSV virus by leaf disk assay, and T. tabaci showed potential for a high capacity to transmit tospovirus on onion isolate.
Factors determining vector competence and specificity for transmission of Tomato spotted wilt virus.
TLDR
The rate of virus replication in the midgut and the extent of virus migration from the midGut to the visceral muscle cells and the salivary glands are probably crucial factors in the determination of vector competence.
Sources of resistance to tomato spotted wilt virus (TSWV) in cultivated and wild species of Capsicum
TLDR
The experimental results strongly indicate there exists a number of genetic mechanisms (probably including action of vertical and horizontal genes) to TSWV resistance in Capsicum spp.
Genome analysis of a severe and a mild isolate of Papaya ringspot virus-type W found in Brazil
TLDR
To aid in understanding the mechanism by which PRSV-W-1 premunization operates, the complete genome sequences of PRS vdW, a mild and premunizing strain ofPRSV, were determined and showed significant evidence that many other fully sequenced PRSSV genomes were recombinant.
