Aggressiveness of Cuban Papaya ringspot virus Isolates on Carica papaya L. cv. Maradol Roja under Greenhouse Conditions
(SciTechnol, 2017-04-16)Carica papaya is a major fruit crop in tropical and subtropical regions; however, its production has several constraints. Papaya ringspot virus (PRSV) is the most important pathogen affecting papaya plantations. Symptoms ... -
Agricultural expansion and the ecological marginalization of forest-dependent people
(National Academy of Sciences, 2021-11-02)Agricultural expansion into subtropical and tropical forests causes major environmental damage, but its wider social impacts often remain hidden. Forest-dependent smallholders are particularly strongly impacted, as they ... -
Agronomic and molecular characterization of Chloris gayana cultivars and salinity response during germination and early vegetative growth
(CIAT, 2019-01)Chloris gayana is a warm-season grass, often cultivated in areas where soil salinity is a major constraint for forage production. Five cultivars (2 unselected populations and 3 synthetic varieties) were evaluated through ... -
Aislamiento y selección in vitro de endófitos bacterianos de garbanzo con efecto antagónico sobre Ascochyta rabiei, agente causal de la rabia del garbanzo
(Asociación Argentina de Microbiología, 2021-09-15)La rabia del garbanzo, producida por el hongo Ascochyta rabiei puede llegar a producir perdidas de hasta un 100 en condiciones predisponentes Actualmente no se disponen de insumos biológicos para su control Es por eso ... -
Alfalfa dwarf cytorhabdovirus P protein is a local and systemic RNA silencing supressor which inhibis program med RISC activity and prevents transitive amplification of RNA silencing
(2016)Plants employ RNA silencing as an innate defense mechanism against viruses. As a counter-defense, plant viruses have evolved to express RNA silencing suppressor proteins (RSS), which target one or more steps of the ... -
Alfalfa mosaic virus (AMV): genetic diversity and a new natural host
(Springer, 2021-10-15)Alfalfa mosaic virus (AMV) is a plant virus belonging to the genus Alfamovirus in the family Bromoviridae. AMV occurs worldwide and is one of the most important viruses affecting a large number of plant species, mainly ... -
Almacenamiento de carbono en suelos de sistemas silvopastoriles
(CIPAV, 2023-10-01)La producción de ganado es el uso de la tierra más extendido en el planeta, representando una fuente de sustento y crecimiento económico (Thornton et al., 2010; Fernández et al., 2018). En los últimos años ha sido muy ... -
Amenazas asociadas a virus emergentes que infectan papaya en Argentina
(Centro Nacional de Sanidad Agropecuaria (CENSA), Cuba, 2023-05-08)La papaya (Carica papaya) se establece como una alternativa sustentable en el norte de Argentina, donde su producción se ha incrementado significativamente en los últimos años. Considerando el elevado número de virus que ... -
Las amenazas fitosanitarias en la horticultura dentro del contexto de cambio climático
(Ediciones INTA, 2022-10)Los cultivos agrícolas, y en particular los hortícolas, están sometidos cada vez más a la presión de enfermedades, plagas y malezas. Esto se debe a diferentes factores como por ejemplo el cambio climático, que es una de ... -
Amesuviridae: a new family of plant-infecting viruses in the phylum Cressdnaviricota, realm Monodnaviria
(Springer, 2023-08-10)The phylum Cressdnaviricota comprises viruses with single-stranded, circular DNA genomes that encode an HUH-type endonuclease (known as Rep). The phylum includes two classes, eight orders, and 11 families. Here, we report ... -
Ammonium stress increases microautophagic activity while impairing macroautophagic flux in Arabidopsis roots
(Wiley, 2020-11-22)Plant responses to NH4 + stress are complex, and multiple mechanisms underlying NH4 + sensitivity and tolerance in plants may be involved. Here, we demonstrate that macro‐ and microautophagic activities are oppositely ... -
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 ... -
An Autophagy-Related Kinase Is Essential for the Symbiotic Relationship between Phaseolus vulgaris and Both Rhizobia and Arbuscular Mycorrhizal Fungi
(American Society of Plant Biologists, 2016-09)Eukaryotes contain three types of lipid kinases that belong to the phosphatidylinositol 3-kinase (PI3K) family. In plants and Saccharomyces cerevisiae, only PI3K class III family members have been identified. These enzymes ... -
An in silico analysis revealed a novel evolutionary lineage of putative mitoviruses
(Wiley, 2022-09-09)Mitoviruses (family Mitoviridae) are small capsid-less RNA viruses that replicate in the mitochondria of fungi and plants. However, to date, the only authentic animal mitovirus infecting an insect was identified as Lutzomyia ... -
An In Vitro Method for Studying the Three-Way Interaction between Soybean, Rhizophagus irregularis and the Soil-Borne Pathogen Fusarium virguliforme
(2017-06)In this work, we described an in vitro system adequate for investigating the pathosystem soybean/arbuscular mycorrhizal fungi (AMF)/Fusarium virguliforme. Pre-mycorrhized plantlets with Rhizophagus irregularis were infected ... -
