| near identity of 3- rna secondary structure in bromoviruses and cucumber mosaic virus. | the 3- terminal sequences of rnas 1, 2, 3 and 4 from each of the three bromoviruses (brome mosaic, cowpea chlorotic mottle and broad bean mottle viruses) and also from cucumber mosaic virus display interviral sequence similarity in addition to strong intraviral homology. interviral similarity is much more evident when rna secondary, rather than primary, structures are compared. the last 190 bases of the various rnas can fold into strikingly similar, extensively base-paired secondary structures w ... | 1981 | 7214524 |
| histochemical visualization of ros and antioxidant response to viral infections of vegetable crops grown in azerbaijan. | extremes of environmental conditions, such as biotic stresses, strongly affect plant growth and development and may adversely affect photosynthetic process. virus infection is especially problematic in crops, because unlike other diseases, its impact cannot be reduced by phytosanitary treatments. the vegetable crops (solanum lycopеrsicum l, cucurbita melo l., cucumis sativus l., piper longum l., solánum melongéna l., vicia faba l.) showing virus-like symptoms were collected from fields located i ... | 2014 | 24661407 |
| ecogenomic survey of plant viruses infecting tobacco by next generation sequencing. | the invasion of plant by viruses cause major damage to plants and reduces crop yield and integrity. devastating plant virus infection has been experienced at different times all over the world, which are attributed to different events of mutation, re-assortment and recombination occurring in the viruses. strategies for proper virus management has been mostly limited to eradicating the vectors that spreads the plant viruses. however, development of prompt and effective diagnostic methods are requ ... | 2016 | 27814723 |
| genetic compositions of broad bean wilt virus 2 infecting red pepper in korea. | the incidence of broad bean wilt virus 2 (bbwv2) on red pepper was investigated using the samples obtained from 24 areas of 8 provinces in korea. two hundred and five samples (79%) out of 260 collected samples were found to be infected with bbwv2. while the single infection rate of bbwv2 was 21.5%, the co-infection rate of bbwv2 with cucumber mosaic virus, pepper mottle virus, pepper mild mottle virus and/or potato virus y was 78.5%. to characterize the genetic diversity of bbwv2 korean isolates ... | 2013 | 25288954 |
| first report of cucumber mosaic virus subgroups i and ii on soybean, pea, and eggplant in iran. | cucumber mosaic virus (cmv) has the widest host range (> 1000 plant species) of any known plant virus, a large number of vector species, and a wide geographical distribution. a survey was conducted to determine the incidence of cmv of subgroups i and ii on selected host crops in northern iran. a total of 935 leaf samples from 10 host crops (tomato, pea, tobacco, soybean, watermelon, broad bean, squash, cucumber, eggplant, and lettuce) showing virus disease-like symptoms were collected in 12 citi ... | 2012 | 22720706 |
| detection of new viruses in alfalfa, weeds and cultivated plants growing adjacent to alfalfa fields in saudi arabia. | a total of 1368 symptomatic plant samples showing different virus-like symptoms such as mottling, chlorosis, mosaic, yellow mosaic, vein clearing and stunting were collected from alfalfa, weed and cultivated plant species growing in vicinity of alfalfa fields in five principal regions of alfalfa production in saudi arabia. das-elisa test indicated occurrence of 11 different viruses in these samples, 10 of which were detected for the first time in saudi arabia. eighty percent of the alfalfa sampl ... | 2017 | 28855829 |
| virus diseases of peas, beans, and faba bean in the mediterranean region. | in the mediterranean region, pea, bean, and faba bean production is affected by around 17 major viruses. these viruses do not have the same ecology and consequently require a variety of different preventive measures to control them. some of these viruses have a narrow host range, such as faba bean necrotic yellows virus (fbnyv), and others, such as alfalfa mosaic virus (amv) and cucumber mosaic virus (cmv), a very wide host range. such features are important when identifying sources of virus ino ... | 2012 | 22682174 |
| foliar application of the leaf-colonizing yeast pseudozyma churashimaensis elicits systemic defense of pepper against bacterial and viral pathogens. | yeast associates with many plant parts including the phyllosphere, where it is subject to harsh environmental conditions. few studies have reported on biological control of foliar pathogens by yeast. here, we newly isolated leaf-colonizing yeasts from leaves of field-grown pepper plants in a major pepper production area of south korea. the yeast was isolated using semi-selective medium supplemented with rifampicin to inhibit bacterial growth and its disease control capacity against xanthomonas a ... | 2017 | 28071648 |
| [spontaneous hosts of broad bean wilt virus. communication]. | of 110 plant species, grown from seeds in the vicinity of sources of broad bean wilt virus (bbwv) in 1974, exactly 50% proved to be infected by the mentioned virus within one vegetation period. obviously 54 of the species are previously unknown hosts of bbwv. they belong to the following 21 families: amaranthaceae, boraginaceae, campanulaceae, caryophyllaceae, chenopodiaceae, commelinaceae, compositae, cruciferae, euphorbiaceae, hydrophyllaceae, labiatae, leguminosae, loasaceae, papaveraceae, po ... | 1977 | 878706 |
