The objective of this study was to evaluate the metabolic profile of cattle fed with or without zearalenone (ZEN) and sterigmatocystin (STC)-contaminated diets using a gas chromatography-mass spectrometry metabolomics approach. Urinary samples were collected from individual animals (n = 6 per herd) from fattening female Japanese Black (JB) cattle herds (23 months old, 550-600 kg). Herd 1 had persistently high urinary ZEN and STC concentrations due to the presence of contaminated rice straw. Herd 2, the second female JB fattening herd (23 months old, 550-600 kg), received the same dietary feed as Herd 1, with non-contaminated rice straw...

Wheat dwarf virus (WDV), barley yellow striate mosaic virus (BYSMV), rice black-streaked dwarf virus (RBSDV) and northern cereal mosaic virus (NCMV) are four viruses infecting wheat and causing similar symptoms. In this paper, a multiplex reverse transcription polymerase chain reaction (m-RT-PCR) method has been developed for the simultaneous detection and discrimination of these viruses. The protocol uses specific primer set for each virus and produces four distinct fragments (273, 565, 783 and 1296bp), detecting the presence of RBSDV, BYSMV, WDV and NCMV, respectively...

Open-air burning of agricultural wastes from crops like corn, rice, sorghum, sugar cane, and wheat is common practice in Mexico, which in spite limiting regulations, is the method to eliminate such wastes, to clear the land for further harvesting, to control grasses, weeds, insects, and pests, and to facilitate nutrient absorption. However, this practice generates air pollution and contributes to the greenhouse effect. Burning of straws derived from the said crops was emulated in a controlled combustion chamber, hence determining emission factors for particles, black carbon, carbon dioxide, carbon monoxide, and nitric oxide throughout the process, which comprised three apparent stages: pre-ignition, flaming, and smoldering...

Protein phosphatases (PPs) counteract kinases in reversible phosphorylation events during numerous signal transduction pathways in eukaryotes. PP2Cs, one of the four major classes of serine/threonine specific PPs family is greatly expanded in plants. Thus PP2C is thought to have a specific role in a signal transduction pathway. Some rice PP2Cs classified to subgroup K were responsive to the infection by the compatible Xanthomonas oryzae pv. oryzae, the causal agent of bacterial blight. In A. thaliana, orthologous PP2C genes (AtPP2C62 and AtPP2C26) classified to subgroup K were also responsive to Xanthomonas campestris pv...

BACKGROUND: Synergism between southern rice black-streaked dwarf virus (SRBSDV) and rice ragged stunt virus (RRSV) not only aggravates disease symptoms but also enhances their vector acquisition efficiencies by increasing both viruses' titers in co-infected rice plants, which may exacerbate the epidemic of both viruses and cause significant damage to rice production. The molecular mechanism of viral synergism of these two viruses remains unexplored. METHODS: Single and double infection of SRBSDV and RRSV were obtained with the viruliferous white-backed planthopper and brown planthopper inoculation on four-leaf stage rice seedlings, respectively, under experimental condition...
