Occurrence, Distribution, and Relative Incidence of Five Viruses Infecting Cucurbits in the State of São Paulo, Brazil.
TLDR
Plants that were symptomatic but negative by PTA-ELISA might be due to abiotic agents, infection by virus for which antiserum was not available, such as Squash mosaic virus, or infection with an as yet uncharacterized virus.
Diversity and Localization of Bacterial Endosymbionts from Whitefly Species Collected in Brazil
TLDR
This study is the first survey of whitely populations collected in Brazil, and provides further insights into the complexity of infection with secondary endosymbionts in whiteflies.
Resistance to Passion fruit woodiness virus in Transgenic Passionflower Expressing the Virus Coat Protein Gene.
TLDR
The results of three successive mechanical inoculations against the transgenic plants using three PWV isolates showed that the primary transformant T2 of IAC-277 was immune to all isolates.
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.
Occurrence of Groundnut ringspot virus on Brazilian peanut crops
A high incidence of plants with mosaic, chlorotic spots, ringspots, necrosis, smaller leaves, and stunting was observed on peanut crops (Arachis hypogaea L.) in Itápolis, São Paulo State, Brazil.
Screening of Passiflora species for reaction to Cowpea aphid-borne mosaic virus reveals an immune wild species
TLDR
Cowpea aphid-borne mosaic virus (CABMV) is a potyvirus that causes the most serious virus disease of passion fruit crops in Brazil and only P. suberosa, a wild species, was resistant to infection by all virus isolates, in two independent assays.
Diseases of Passion Flower (Passiflora spp.)
TLDR
The main passion fruit diseases, their symptoms, etiology, epidemiology and management are covered, including bacterial spot, root and collar rot, fusarium wilt, anthracnose and scab, which are the most important.
Occurrence of Tomato chlorosis virus in tomato crops in five Brazilian states
TLDR
This is the first ToCV report for the states of BA, ES, GO, MG, and RJ, suggesting that this virus is widely disseminated in Brazil.
Biological and molecular characterization of Brazilian isolates of Zucchini yellow mosaic virus
TLDR
The nucleotide sequence variability of the coatprotein gene ranged from 82 % to 99 % compared to the corresponding sequences of ZYMV isolates from different geographical locations, and no recombination event was detected in the coat protein gene of the isolates.
