Epidemiology and management of tomato spotted wilt in peanut.
Tomato spotted wilt caused by thrips-vectored tomato spotted wilt virus (TSWV) is a very serious problem in peanut (Arachis hypogaea L.) production. TSWV and the thrips Frankliniella fusca and Frankliniella occidentalis, which vector the virus, present a difficult and complicated challenge from the perspectives of both epidemiology and disease management. Simply controlling the vector typically...
متن کاملEvaluation of Frankliniella Bispinosa (thysanoptera: Thripidae) as a Vector of the Tomato Spotted Wilt Virus in Pepper
Frankliniella occidentalis is the key vector responsible for the emergence of Tomato spotted wilt virus as a global threat to agriculture. Frankliniella bispinosa is a common thrips in Florida, the Bahamas, and Bermuda, but the role of F. bispinosa in the epidemiology of the virus is not known. The purpose of this study was to determine the ability of F. bispinosa to acquire and transmit Tomato...
متن کاملAlfalfa mosaic virus RNAs serve as cap donors for tomato spotted wilt virus transcription during coinfection of Nicotiana benthamiana.
Tomato spotted wilt virus (TSWV) was shown to use alfalfa mosaic virus (AMV) RNAs as cap donors in vivo during a mixed infection in Nicotiana benthamiana. By use of nested reverse transcription-PCR, TSWV N and NSs mRNAs provided with capped leader sequences derived from all four AMV RNAs could be cloned and sequenced. The sequence specificity of the putative TSWV endonuclease involved is discus...
متن کاملMolecular cloning and terminal sequence determination of the S and M RNAs of tomato spotted wilt virus.
Complementary DNA to the genomic RNA of tomato spotted wilt virus (TSWV) was synthesized and cloned in either pUC19 or lambda gt10. Restriction endonuclease maps were constructed from cDNA clones specific for the S and the M RNA segments, extending 3.0 and 5.4 kbp respectively. The nucleotide sequences of the 3' and 5' termini of both RNA molecules were determined. The S and M RNAs contain inve...
متن کاملBiology and Ecology of Flower Thrips in Relation to Tomato Spotted Wilt Virus
Tomato Spotted Wilt Virus (TSWV) is transmitted exclusively by certain species of thrips. Because TSWV can only be acquired by larvae and transmitted by adults, it is essential to determine the ecology of these different life stages to improve management of thrips and TSWV. Furthermore, interspecific differences among vector species complicate management issues. Herein, aspects of the biology a...
متن کاملGenetic mapping of the Tsw locus for resistance to the Tospovirus Tomato spotted wilt virus in Capsicum spp. and its relationship to the Sw-5 gene for resistance to the same pathogen in tomato.
The Tsw gene conferring dominant resistance to the Tospovirus Tomato spotted wilt virus (TSWV) in Capsicum spp. has been tagged with a random amplified polymorphic DNA marker and mapped to the distal portion of chromosome 10. No mapped homologues of Sw-5, a phenotypically similar dominant TSWV resistance gene in tomato, map to this region in C. annuum, although a number of Sw-5 homologues are f...
