gomphrena arborescens/ニコチン

The cells in the local chlorotic areas of Gomphrena globosa L. leaves infected with tobacco mosaic virus (TMV) accumulate a significant amount of viral particles. The cells in the surrounding tissue have a relatively low number of virions, which are often degraded. The cells surrounding the forming

Zamia furfuracea (Zamiaceae) is native of coastal Mexico. It is a popular houseplant and easy to grow outdoors in warm climates. In November 2005, a plant of Z. furfuracea, originally from Texas, was received at the Division of Plant Industry in Gainesville, FL. The plant had numerous chlorotic

Kudzu is an introduced legume commonly found growing as a perennial throughout the southeastern United States. This fast-growing vine was originally planted as an ornamental for forage and to prevent erosion (2), but is now considered an invasive species. During April 2011, a kudzu plant growing

Guizotia abyssinica (L.f.) Cass. (niger), an important oil seed crop grown in India, is used in foods, paints, soaps, and as an illuminant. During a survey conducted in 2004 to monitor Tobacco streak virus (TSV) in Helianthus annuus L. (sunflower) and Arachis hypogaea L. (groundnut), typical

Tobacco streak virus (TSV) is an ilarvirus with a worldwide distribution. This virus infects many plants and causes significant yield losses. In this study, 300 samples of lettuce were collected from lettuce fields in Tehran Province. Infected plants show symptoms such as: mosaic, vein clearing,

Cucumber (Cucumis sativus L.) and Gherkin (Cucumis anguria L.) are important cucurbitaceous vegetables grown in India for slicing and pickling. During the 2000 to 2002 rainy season and summer, a new virus disease, causing yield losses of 31 to 75% in Bangalore, Bellary, Davanagiree, and Tumkur

Prayer plants (Maranta spp.), which are indigenous to Brazil, are commercially produced in nurseries mainly to be sold as potted houseplants. However, in frost-free areas, they are also used as a ground cover. In March 2009, the Division of Plant Industry in Gainesville, FL received cuttings of

Unusual symptoms were observed in summer 1997 in field zucchini of several cultivars grown in central Italy. Symptoms included reduction in growth, severe mosaic, blistering and deformation of leaves, and malformation on fruits. Plants gave negative results in enzyme-linked immunosorbent assay

Zamioculcas zamiifolia (Lodd.) Engl. ("Zanzibar Gem," "ZZ plant") is the monotypic species of the genus belonging to the family Araceae. It is a stemless perennial plant native to Africa, from Kenya to South Africa, that produces succulent rhizomes at the base of its attractive

Alfalfa mosaic virus (AMV) has a wide host range and is distributed throughout the world. It causes disease in several vegetable crops, including bean, celery, lettuce, pea, pepper, and tomato (1). In Spain, it has been found naturally infecting alfalfa, pepper, and tomato. During the autumn of

During 2001 and 2002, Pisum sativum var. vulgare plants grown as commercial crops in Almeria (southeast Spain) showed vein clearing and chlorotic mottle of leaves, leaf deformation, flower abortion, necrotic mottle and deformation of pods, and stunted plant growth. Crude sap of collected plants was

During the summers of 1999 and 2000, 3,110 soybean (Glycine max) leaf samples were randomly collected from soybean fields in the Ardebil, Goletan, Khuzestan, Lorestan, and Mazandaran provinces of Iran. Tomato spotted wilt virus (TSWV) was detected in leaf samples by TSWV-specific polyclonal antibody

Potato virus X (PVX) isolated from the potato leaf and tuber samples which were collected from various fields in Damavand and Ardabil. The initial isolations of the virus were made from potato by mechanical inoculation on Gomphrena globosa L. and Chenopodium spp. that produce local lesion, and then

Potato virus x (PVX) is found commonly in potato-growing areas, worldwide. It is an economically important virus which causes losses in tuber yield of approximate 5 to 15 percent. In a 2 year survey, potato leaf and tuber samples were collected from various fields in Damavand and Karaj. The initial
