A non-targeted approach unravels the volatile network in peach fruit
(2012)Volatile compounds represent an important part of the plant metabolome and are of particular agronomic and biological interest due to their contribution to fruit aroma and flavor and therefore to fruit quality. By using a ... -
A Note on the Association Between Thecaphora frezzii Infection and Peanut Pod Density
(American Peanut Research and Education Society, 2021)The time and labor required to hand-screen germplasm are significant obstacles to developing cultivars resistant to peanut smut, but researchers have investigated few alternatives to manual disease evaluations. Although ... -
A novel EPSPS Pro-106-His mutation confers the first case of glyphosate resistance in Digitaria sanguinalis
(Wiley, 2022-04)BACKGROUND: Digitaria sanguinalis has been identified as a species at high risk of evolving herbicide resistance, but thus far, there are no records of resistance to glyphosate. This species is one of the most common weeds ... -
A novel mechanism to simulate intercropping and relay cropping using the DayCent model
(Elsevier, 2022-01-03)Combining different crops in complex spatial and temporal arrangements can increase resource use efficiency and reduce negative environmental impacts in croplands. Simulation models are useful tools to explore new management ... -
A novel pathogenic mechanism for cerebellar lesions produced by Solanum bonariense in cattle
(American Association of Veterinary Laboratory Diagnosticians, 2015-05)Intoxication with Solanum bonariense in cattle causes cerebellar cortical degeneration with perikaryal vacuolation, axonal swelling, and death primarily of Purkinje cells, with accumulation of electron-dense residual storage ... -
A novel real-time PCR assay for quantitative detection of Campylobacter fetus based on ribosomal sequences
(BMC, 2016-12)Background: Campylobacter fetus is a pathogen of major concern for animal and human health. The species shows a great intraspecific variation, with three subspecies: C. fetus subsp. fetus, C. fetus subsp. venerealis, and ... -
A novel spotted fever group Rickettsia infecting Amblyomma parvitarsum (Acari: Ixodidae) in highlands of Argentina and Chile
(2016)The tick Amblyomma parvitarsum (Acari: Ixodidae) has established populations in Andean and Patagonic environments of South America. For the present study, adults of A. parvitarsum were collected in highland areas (elevation ... -
A one-year longitudinal study of enterohemorrhagic Escherichia coli O157 fecal shedding in a beef cattle herd
(Elsevier, 2019-12-01)Bovines are the primary reservoir of enterohemorrhagic Escherichia coli (EHEC) O157:H7 and the main source of its transmission to humans. Here, we present a one-year longitudinal study of fecal shedding of E. coli O157. ... -
A paradigm shift to CO2 sequestration to manage global warming – With the emphasis on developing countries
(Elsevier, 2021-06-01)Global land use changes that tend to satisfy the food needs of augmenting population is provoking agricultural soils to act as a carbon (C) source rather than sink. Agricultural management practices are crucial to offset ... -
A pictorial key to differentiate the recently detected exotic Haemaphysalis longicornis Neumann, 1901 (Acari, Ixodidae) from native congeners in North America
(Pensoft Publishers, 2019-01)Until recently, only two haemaphysaline species, Haemaphysalis chordeilis (Packard, 1869) and Haemaphysalis leporispalustris (Packard, 1869), were known to occur in the United States, and neither was considered to be of ... -
A practical guide to estimating the light extinction coefficient with nonlinear models—a case study on maize
(Springer Nature, 2021-06-12)The fraction of intercepted photosynthetically active radiation (fPARi) is typically described with a non-linear function of leaf area index (LAI) and k, the light extinction coefficient. The parameter k is used to make ... -
A preliminary study of spatial distribution and plant density in a leucaena-grass planting in north Corrientes, Argentina
(CIAT, 2019)In northeast Argentina, most beef cattle graze naturalized range pastures continuously, with limited winter supplementation and restricted access to improved pastures. Calving rates are low, averaging 40‒50% annually and ... -
A preliminary study on the effects of a transgenic corn event on the non-target pest Dalbulus maidis (Hemiptera: Cicadellidae)
(Elsevier, 2010-06)The inclusion of the cry gene in corn may produce direct effects on non-target pests. Our research was focused on the relationship between Bt corn germplasm, expressing the cry1F protein to control the fall armyworm ... -
