Plan S: take Latin America’s long experience on board
(Nature Research, 2019-09-24)We share the spirit of Plan S to achieve full open access to scholarly publications (see go.nature.com/2hszsaf), but we disagree with its implementation guidelines. The plan’s design ignores more than 20 years of widespread ... -
Plant Biology: New Insight into How Roots 'Mask Up'
(Cell Press, 2021-03-08)Extra- and trans-cellular barriers are essential for root function under even mild stress. New research shows that establishing both the lignin and suberin barriers in the Arabidopsis endodermis requires phenylpropanoid ... -
Plant microRNAs: Recent Advances and Future Challenges
(2014-12)MicroRNAs (miRNAs) are small ∼20–24 nt species of non-coding RNAs that modulate plant gene expression by means of gene silencing through sequence-specific inhibition of target mRNAs. MiRNAs derive from pol-II transcription ... -
Plant Tolerance Mechanisms to Soil Salinity Contribute to the Expansion of Agriculture and Livestock Production in Argentina
(Springer, 2021)This chapter addresses salt tolerance mechanisms in crops and woody species cultivated in Argentina, highlighting the contribution of local research to these topics. Work on forages and woody species represents approximately ... -
Plant-Derived Essential Oils and Aqueous Extract as Potential Ingredients for a Biopesticide: Phytotoxicity in Soybean and Activity against Soybean Mosaic Virus
(MDPI, 2023-07-27)Soybean mosaic disease, caused by the soybean mosaic virus (SMV), is responsible for major losses in yield and seed quality worldwide. Although resistant cultivars are used for its prevention and control, an alternative ... -
Plants causing poisoning outbreaks of livestock in South America: A review
(Elsevier, 2023-01-21)According to Tokarnia et al. (2012), “poisonous plants of livestock interest are those that, when ingested by farm animals under natural conditions, cause health problems or death.” Following this definition, we include ... -
Plasticity in sunflower leaf and cell growth under high salinity
(Wiley, 2015-01)A group of sunflower lines that exhibit a range of leaf Na+ concentrations under high salinity was used to explore whether the responses to the osmotic and ionic components of salinity can be distinguished in leaf expansion ... -
Plataforma virtual con información para el manejo de enfermedades de maíz
(Brevant Semillas, 2020-10)A través de un proyecto COFECYT, desde octubre de 2019, se están llevando a cabo acciones tendientes a formar una plataforma virtual con información sobre las diferentes enfermedades del cultivo del maíz para la provincia ... -
Plataforma virtual sobre enfermedades en el cultivo de maíz en la provincia de Córdoba
(Universidad Nacional del Noroeste de la Provincia de Buenos Aires -UNNOBA, 2022-10-19)En maíz, la información de presencia, incidencia y severidad de enfermedades es clave en la decisión de siembra y elección de híbridos, así como para el manejo del cultivo. -
Plum Pox virus in japanese plum from Argentina: serological detection and molecular characterization of an isolate from cv. Red Beauty
(Wiley, 2014-01)A Plum pox virus (PPV) isolate detected in a Japanese plum orchard in Pocito (San Juan, Argentina) was transmitted mechanically to Prunus tomentosa and Nicotiana benthamiana. DAS-ELISA and DASI-ELISA indicated the virus ... -
Polyamines and flavonoids : key compounds in mycorrhizal colonization of improved and unimproved soybean genotypes
(Springer, 2018-11)Modern breeding programs might have caused a reduction in plant responsiveness to arbuscular mycorrhizal fungi (AMF). Flavonoids and polyamines (PAs) are hypothesized to play a role in this symbiosis. We tested the effects ... -
Polyamines and Legumes: Joint Stories of Stress, Nitrogen Fixation and Environment
(Frontiers Media, 2019-11-04)Polyamines (PAs) are natural aliphatic amines involved in many physiological processes in almost all living organisms, including responses to abiotic stresses and microbial interactions. On other hand, the family Leguminosae ... -
