ABSTRACT The partial nucleotide sequence of the coat protein (CP) gene Ethiopian isolates chickpea chlorotic stunt virus (CpCSV, genus Polerovirus ), beet western yellows (BWYV, and soybean dwarf (SbDV, Luteovirus ) was determined from lentil plants showing yellowing, stunting, reddening symptoms. Comparative analysis CpCSV obtained five showed 94.9%–100% 91.9%–98.7% identity with each other reference isolates, respectively. One isolate (MZ043728) a close relationship serotype II while...
Abstract Field surveys were conducted in Syria during the 2005/2006 and 2006/2007 growing seasons to identify viruses which affect cool‐season food legumes, volunteer crops, weeds with yellowing, reddening and/or stunting symptoms. Serological tests (tissue blot immunoassay) showed that Faba bean necrotic yellows virus luteoviruses including, Beet western , Bean leafroll Soybean dwarf main identified. In addition, a large number of samples reacted positively broad spectrum legume luteovirus...
A field survey covering the major cereal-production areas of Syria was conducted during May 2009. total 938 wheat and 971 barley samples with typical symptoms viral infection were collected from 45 58 fields. All tested by tissue-blot immunoassay (1) at Virology Laboratory ICARDA, using six specific cereal virus antisera, including polyclonal antibody AS-0216 for Wheat dwarf (WDV) provided German Collection Microorganisms Cell Cultures (DSMZ). Serological tests showed that WDV detected in 16...
A survey to identify virus diseases affecting legume (chickpea, faba bean and lentil) cereal (bread and durum wheat barley) crops at different locations in Tunisia was conducted April, 2000. Thirty-eight legume fields (34 bean, 3 chickpea one 43 fields (21 durum wheat, 7 bread 15 barley) were randomly selected. The identity of the viruses disease incidence determined on 100-200 randomly collected samples 20-25 symptomatic from each field by testing against antisera 12 legume and 6 viruses....
Cactaceae comprise a diverse and iconic group of flowering plants which are almost exclusively indigenous to the New World. The wide variety growth forms found amongst cacti have led trafficking many species throughout world as ornamentals. Despite evolution physiological properties these having been extensively studied, little research has focused on cactus-associated viral communities. While only single-stranded RNA viruses had ever reported in cacti, here we report discovery...
A virus disease of faba bean (Vicia L.) in China, characterized by leaf yellowing and rolling plant stunting, was shown to be caused a the genus Nanovirus based on serological reactions nanovirus-specific monoclonal antibodies generation polymerase chain reaction amplicons using primers. To identify bean-infecting nanovirus, regions DNA components encoding master replication initiator protein capsid two nanovirus isolates from China were cloned, sequenced compared with those other members...
An intensive survey was conducted during May–June, 2001 to identify virus diseases affecting chickpea (Cicer arietinum) and lentil (Lens culinaris) crops in five provinces (Qazvin, Kermanshah, Kurdistan, East Azarbaijan West Azarbaijan) of Iran. A total 6979 1760 samples were collected randomly from 51 13 fields (100–150 per field). These tested for the presence different legume viruses by tissue-blot immunoassay procedure (Lin et al., 1990), using a battery polyclonal monoclonal antibodies....
A survey to identify virus diseases affecting chickpea crops in the major production areas of Eritrea was conducted during November 2005. The covered 31 randomly selected fi elds. Virus disease incidence was determined on basis laboratory testing 100–200 collected samples from each eld against antisera 9 legume viruses. Serological tests indicated that Luteoviruses were most common, with an overall incidence 5.6%, followed by Faba bean necrotic yellows (FBNYV, genus Nanovirus, family...
typical of virus infection (chlorosis, stunting, necrosis, yellowing, and reddening) were collected during disease
Abstract Detection of bean yellow mosaic virus (BYMV), impatiens necrotic spot (INSV) and lily symptomless (LSV) by dot‐blot tissue‐blot immunoenzymatic assay was compared using either chromogenic or chemiluminescent substrates. Testing conducted on infected‐leaf extracts purified preparations. Both types substrates gave comparable results with leaf extracts. However, virus, the use led to a more sensitive detection three viruses.
During May 2003, a high incidence of symptoms suggestive virus infection in spring chickpea were observed many fields Al-Ghab Valley, Syria, the ICARDA farm (near Aleppo, Syria), as well other locations northern including Idleb governorate. Symptoms yellowing, stunting, and necrosis. A total 1,345 samples with these (331 from 269 farm, 745 governorate) collected tested for presence five viruses tissue-blot immunoassay (TBIA) (4) at Virology Laboratory ICARDA, using following antisera:...
