avena sativa/necrosis

Oats are gaining increasing scientific and public interest for their purported antioxidant-associated health benefits. Most reported studies focused on specific oat extracts or particular oat components, such as β-glucans, tocols (vitamin E), or avenanthramides. Studies on whole oats with respect to

Eukaryotic initiation factor (eIF) 4B is known to interact with multiple initiation factors, mRNA, rRNA, and poly(A) binding protein (PABP). To gain a better understanding of the function of eIF4B, the two isoforms from Arabidopsis (Arabidopsis thaliana) were expressed and analyzed using biophysical

Sorghum (Sorghum bicolor) line Tx2786 is immune to strains or isolates of sorghum mosaic potyvirus (SrMV strains SCH and SCH) but susceptible to strains of maize dwarf mosaic (MDMV) and sugarcane mosaic (SCMV) potyviruses (1,2). When grown in proximity to sugarcane, Tx2786 was infected with a virus

Maize (Zea mays) has become an important crop in Poland with a constant increase in crop acreage since the 1990s. In 2007, maize plants with characteristic leaf mosaic were observed in two locations in the Wielkopolska Region near Poznań and Krotoszyn. Ninety-two samples from plants showing leaf

Wide hybridization is a one of the important techniques in plant breeding. Oat (Avena sativa L.) and pearl millet (Pennisetum glaucum L.) belong to different subfamilies of Poaceae. In generally, such distant relative species show uniparental chromosome elimination after successful fertilization.

A potyvirus (proposed name of Zea mosaic virus [ZeMV]) isolated from maize in Israel was analyzed by serology, sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) of capsid proteins, symptomatology, and sequencing. Parts of the nuclear inclusion b, coat protein, and 3' regions were

Nootkatone is a component of grapefruit oil that is toxic to the disease-vectoring tick, Ixodes scapularis Say, but unfortunately causes phytotoxicity to treated plants and has a short residual activity due to volatility. We prepared a lignin-encapsulated nootkatone formulation to compare with a

During a growing season in 2004, 231 leaf samples of virus infected and mosaic and dwarf mosaic symptoms showing maize (Zea mays L.) plants and 258 leaf samples of mosaic showing johnsongrass (Sorghum halepens L.) plants from various corn fields in Tehran province were collected. Serological tests

Approximately 15,000 ha of melon (Cucumis melo L.) are grown in the northeastern section of Brazil, mostly for export to Europe during the winter months. Surveys for melon vine decline diseases were carried out in farms in the municipalities of Mossoró (Rio Grande do Norte) and Quixeré (Ceará)

Oat (Avena sativa L.) mesophyll protoplasts were recently demonstrated to be capable of dedifferentiation, repeated divisions, and colony formation. Since the development of oat mesophyll protoplasts is decisively influenced by the nature of the used feeder culture (species, variety and

Field outbreaks of a syndrome of unknown aetiology associated with the grazing of green oats (Avena sativa) in the south-western Cape Province were characterized by diarrhoea, photosensitivity and death in goats and by diarrhoea and a reduction in milk production in cows. A phytopathogenic fungus,

ABSTRACT Infection types produced by Puccinia graminis f. sp. avenae on plants of Avena sativa with the stem rust resistance gene Pg10 are characterized by moderate-sized uredinia surrounded by an area of chlorosis and a larger variable zone of dark brown necrosis. This study was undertaken to

In 2008 and 2009, vine decline symptoms were observed in three watermelon (Citrullus lanatus (Thunb.) Matsum. & Nakai) fields located in the municipalities of Mossoró (Rio Grande do Norte State) and Quixeré (Ceará State) in northeastern Brazil. Symptoms included yellowing of crown leaves just

In 2010 and 2011, diseased watermelon plants (Citrillus lanatus [Thunb.] Matsun and Nakai) had chlorotic and wilted leaves and vines prior to harvest in three out of four sampled commercial fields in the Municipality of Matamoros, State of Coahuila, in the north-central region of Mexico known as La

To test the possible interaction of polyamines in plant growth responses, transgenic tobacco plants containing the Avena sativa L. (oat) arginine decarboxylase (ADC) gene under the control of a tetracycline-inducible promoter were generated. Inducible overexpression of oat ADC in transgenic tobacco
