Reconstruction and characterization of full-length begomovirus and alphasatellite genomes infecting pepper through metagenomics
(MDPI, 2020-02)In northwestern Argentina (NWA), pepper crops are threatened by the emergence of begomoviruses due to the spread of its vector, Bemisia tabaci (Gennadius). The genus Begomovirus includes pathogens that can have a monopartite ... -
Redefining the medicago sativa alphapartitiviruses genome sequences
(Elsevier, 2019-03-29)In Argentina, alfalfa (Medicago sativa L.) is a primary forage crop and a major feed component in dairy and beef cattle production systems. In 2010, we observed alfalfa plants showing symptoms of shortened internodes (bushy ... -
Relationship between incidence and severity of peanut smut and its regional distribution in the main growing region of Argentina
(Springer, 2021-10-20)Peanut smut, caused by the soil-borne pathogen Thecaphora frezii, has increased in incidence in the main Argentinian peanut-growing regions. Smut-affected pod transform the kernel into a mass of teliospores, which survive ... -
Relative incidence of cucurbit viruses and relationship with bio-meteorological variables
(Springer, 2020-02)Environmental heterogeneity can shape the plant-virus relationship, furthering the appearance of new diseases in crops, or altering disease incidence and severity. In this work, we studied the virus association with ... -
Response of soil microbial communities to agroecological versus conventional systems of extensive agriculture
(2018-05)World population growth has led to a rise in resource demands imposed on agricultural systems, generating an increased global use of natural resources. However, agroecology proposes self-regulation in order to achieve a ... -
Response of soil microbial communities to different management practices in surface soils of a soybean agroecosystem in Argentina
(Elsevier, 2010-12-03)Argentina is the world’s third most important soybean producer; hence, there is an urgent need to preserve soil health by applying appropriate agricultural practices to maintain sustainable production in the upcoming years. ... -
Sample size for assessment of cladode brown spot in prickly pear cactus
(Springer, 2017-03-15)Cladode brown spot (CBS) is an important disease of prickly pear cactus (Nopalea cochenillifera) in Brazil. No standard method exists for sampling in the field. A study was conducted in 30 fields of prickly pear (cv. Miúda) ... -
Screening for native Trichoderma strains as potential biocontrollers of the olive pathogen Verticillium dahliae
(Taylor and Francis, 2023-07-12)Verticillium dahliae is a soilborne pathogen that causes significant losses in olive crops in northwestern Argentina. Biological control through antagonistic microorganisms such as Trichoderma has great potential in the ... -
Screening of chickpea germplasm for Ascochyta blight resistance under controlled environment
(Springer, 2022-01-13)Chickpea is the third most important grain legume in the world after common bean and pea. Ascochyta blight (AB) of chickpea, caused by Ascochyta rabiei, is the most damaging disease of this crop worldwide. Losses may reach ... -
Sequencing of two Sunflower chlorotic mottle virus isolates obtained from different natural hosts shed light on its evolutionary history
(Springer, 2013-02)Sunflower chlorotic mottle virus (SuCMoV), the most prevalent virus of sunflower in Argentina, was reported naturally infecting not only sunflower but also weeds. To understand SuCMoV evolution and improve the knowledge ... -
Soil microbial communities under different soybean cropping systems: Characterization of microbial population dynamics, soil microbial activity, microbial biomass, and fatty acid profiles
(Elsevier, 2008-12-05)This work analyzes the direct effect of soil management practices on soil microbial communities, which may affect soil productivity and sustainability. The experimental design consisted of two tillage treatments: reduced ... -
Soybean responseto initial stage of Fusarium virguliforme infection
(BioRxiv, 2022-03-07)Fusarium virguliforme causes the Sudden Death Syndrome, an important disease in soybean crops. In this work, we investigated the defensive response mechanisms in soybean root, at cell wall level, during F. virguliforme ... -
Spatio and temporal spread of Plum pox virus infecting European plum (Prunus domestica L. cv. D'agen) orchard in Mendoza, Argentina = Distribución espacial y temporal del Plum pox virus en un monte de ciruelo europeo (Prunus domestica L cv D'agen) de Mendoza, Argentina
(Facultad de Ciencias Agrarias, Universidad Nacional de Cuyo, 2020)Sharka, caused by Plum pox virus (PPV), is considered one of the most serious viral diseases of stone fruits worldwide due to the great yield losses in orchards. In Rama Caída, Mendoza, a 5-year study (2007-2011) was ... -
