Efectos del herbicida glifosato sobre la estructura y el funcionamiento de comunidades microbianas de dos suelos de plantaciones de olivo
(Asociación Argentina de Ecología, 2012-04-01)Los herbicidas pueden alterar la estructura y el funcionamiento del suelo mediante efectos directos sobre varios componentes de su microbiota. Muchos autores han encontrado un efecto perjudicial del glifosato sobre la ... -
Integrated multivariate analysis of selected soil microbial properties and their relationships with mineral fertilization management in a conservation agriculture system
(Taylor & Francis, 2013)The effect of mineral fertilizer application on soil microbial community was investigated in a conservation agriculture system. The aim of this work was to evaluate how mineral fertilization with nitrogen (N), phosphorus ... -
Molecular characterization of a phytoplasma of the ash yellows group occurring in strawberry (Fragaria x ananassa Duch.) plants in Argentina
(2013-01)Strawberry (Fragaria x ananassa Duch. cv. Camino Real) plants showing phyllody symptoms were detected in production fields in Bella Vista (Corrientes province, Argentina). DNA from all symptomatic samples analyzed yielded ... -
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 ... -
Development of a full-length infectious clone of sunflower chlorotic mottle virus (SuCMoV)
(Springer; Virology Division, International Union of Microbiological Societies, 2013-02)A full-length cDNA clone (p35SuCMoV) of the sunflower chlorotic mottle virus common strain (SuCMoV-C) genomic RNA was constructed. Three cDNA fragments covering the whole genome of SuCMoV-C were cloned between a cauliflower ... -
Wheat curl mite, Aceria tosichella, and transmitted viruses: an expanding pest complex affecting cereal crops
(Springer, 2013-02)The wheat curl mite (WCM), Aceria tosichella, and the plant viruses it transmits represent an invasive mite-virus complex that has affected cereal crops worldwide. The main damage caused by WCM comes from its ability to ... -
An analysis of the genomic variability of the phytopathogenic mollicute Spiroplasma kunkelii
(American Phytopathological Society, 2013-02)Corn stunt disease has become a factor limiting maize production in some areas of the Americas in recent years. Although resistant maize genotypes have been developed in the past, this resistance has been unstable over ... -
