The complete RNA genomic sequence of a tobacco mosaic virus isolate infecting Impatiens balsamina, designated as TMV-IM, has been determined. The genomic sequence and the predicted gene products of TMV-IM were similar to those of other members of the genus Tobamovirus. The CP ORF of TMV-IM showed
We generated transgenic tobacco plants expressing the sense or antisense untranslatable N coding sequence of the lettuce isolate of tomato spotted wilt virus (TSWV-BL) as well as transgenic plants containing the promoterless N gene of the virus. Both sense and antisense untranslatable N gene RNAs
Impatiens necrotic spot virus (INSV) (genus Tospovirus; family Bunyaviridae) is a devastating disease in the production of ornamental flowers (1). From 2007 to 2009, a survey of 10 major parks and recreation areas in Kunming, the capital of Yunnan Province, China, indicated that approximately 60 to
Tobamoviruses were detected in two ornamental plants, Dieffenbachia picta (Araceae) and Impatiens hawkeri (Balsaminaceae), from different counties in São Paulo State, Brazil. Symptoms were chlorotic spots and rings in D. picta and mosaic, blistering, and leaf deformation in I. hawkeri. Mechanical
The complete nucleotide sequence of a tobamovirus isolated from Impatiens New Guinea was determined. The genome was 6302 nt long, and its genomic organisation was similar to those of other crucufer tobamoviruses. Sequence comparisons with the corresponding sequences of other crucifer tobamoviruses
Of more than a dozen members of the genus Tospovirus, Tomato spotted wilt virus (TSWV) and Impatiens necrotic spot virus (INSV) are among the most damaging viruses found in North America (3). TSWV is a major problem in vegetable and field crops, whereas INSV is commonly encountered in the
In October 2006 (Arcadia, FL) and January 2007 (Sorrento, FL), several white Phalaenopsis orchids with large chlorotic/necrotic ringspot symptoms were sent to the Division of Plant Industry, Gainesville, FL. Symptomatic leaf tissues were tested with the Agdia immunostick-comb (Agdia, Elkhart, IN)
Impatiens necrotic spot virus (INSV) (genus Tospovirus, family Bunyaviridae) has been detected in commercial nurseries and field-grown ornamentals in Mahallat (Markazi) and Tehran provinces of Iran. INSV on ornamentals was first reported in 1990 (2). Ornamental plants with small necrotic spots, leaf
Impatiens necrotic spot virus (INSV; genus Tospovirus) was detected in experimental greenhouse-grown potatoes (Solanum tuberosum) and Nicotiana benthamiana in New York State in July and August of 2003 and 2004. Potato leaves exhibiting necrotic lesions with a concentric pattern similar to those
There have been an increasing number of records of the natural infection of various crops and ornamentals in Iran with Impatiens necrotic spot virus (INSV), Tomato spotted wilt virus (TSWV), and Tomato yellow fruit ring virus (TYFRV), a recently proposed species in the genus Topovirus (3). TYFRV,
Impatiens necrotic spot virus (INSV), family Bunyaviridae, genus Tospovirus, is an emerging virus found mostly in ornamentals under greenhouse production. INSV has been detected in peanut (Arachis hypogaea L.) in Georgia and Texas (3) and recently in tobacco (Nicotiana tabacum L.) in the
Spinach (Spinacia oleracea) plants exhibiting severe stunting and leaves that showed interveinal yellowing, thickening, and deformation were found in an experimental trial adjacent to an artichoke field in Monterey County, CA in October of 2008. Percent incidence of symptomatic plants ranged from 20
Mexico contributes 20% of the total worldwide pepper exports (1). Impatiens necrotic spot virus (INSV) (genus Tospovirus; family Bunyaviridae) has emerged and has possibly caused diseases in various crops and ornamentals in Mexico. INSV was treated as a quarantine virus in Mexico (2) but not
Impatiens necrotic spot virus (INSV) was found for the first time in the Czech Republic in 1999 in Columnea sp. and Curcuma sp. plants that were imported. They were grown in a garden among other ornamental crops. By June 2000, INSV was detected in 17 ornamental plant species in several gardening
In July 2000, concentric necrotic rings and patterns were observed on greenhouse-grown pepper (Capsicum anuum L. 'Blondi'). Symptoms were present only on lower leaves, not on young leaves or fruits. Typical tospovirus particles using electron microscopy were observed in leaf-dip preparations of
