Assessment of genetic and epigenetic changes in virus-free garlic (Allium sativum L.) plants obtained by meristem culture followed by in vitro propagation
(2016-01)Garlic (Allium sativum) is a worldwide crop of economic importance susceptible to viral infections that can cause significant yield losses. Meristem tissue culture is the most employed method to sanitize elite cultivars. ... -
Assessment of lead tolerance on Glycine max (L.) Merr. at early growth stages
(Springer, 2021-01-11)Lead (Pb) contamination of agricultural soils, and subsequently of crops, has been widely reported. Soybean (Glycine max (L.) Merr.) has been indicated as a plant that accumulates Pb, even in soils that do not exceed the ... -
Bacillus subtilis ALBA01 alleviates onion pink root by antagonizing the pathogen Setophoma terrestris and allowing physiological status maintenance
(Springer, 2020)The soil-borne pathogen Setophoma terrestris is the causal agent of pink root of onion, one of the most challenging diseases in onion production. Conventional approaches for managing the disease like solarization, soil ... -
A bacterial endophyte from apoplast fluids protects canola plants from different phytopathogens via antibiosis and induction of host resistance
(American Phytopathological Society, 2019-03)Endophytic bacteria colonize inner plant tissues and thrive at the apoplast, which is considered its main reservoir. Because this niche is the place where the main molecular events take place between beneficial and pathogenic ... -
Benchmarking Nutraceutical Soybean Composition Relative to Protein and Oil
(Frontiers Media, 2021-08-11)The aim of this study was to explore relationships between protein, oil, and seed weight with seed nutraceutical composition, focused on total isoflavone (TI) and total tocopherol (TT) contents across genotypic and ... -
Los bioinsumos en el mundo forestal: ¿mejoran el crecimiento en vivero de plantas de algarrobo blanco?
(Colegio de Graduados en Ciencias Forestales de Santiago de Estero, 2023)¿Qué es un bioinsumo?, es una pregunta necesaria para poder comprender que se trata de aquellos productos de origen biológico (vegetal, animal o microbiano) usados para mejorar la productividad, sanidad o tolerancia al ... -
Biological nitrogen fixation in soybean in Argentina: relationships with crop, soil, and meteorological factors
(2015-07)Aims: This study aims to (i) asses the contribution of biological N fixation (%Ndfa) in the soybean production area of Argentina, (ii) build a model for predicting %Ndfa using crop, soil, and meteorological variables, and ... -
Bosques monotípicos de Gonopterodendron sarmientoi: ambiente, genética y morfología de los palosantales
(Asociación Argentina de Ecología, 2022-06-26)Gonopterodendron sarmientoi —Palo Santo— es una especie forestal típica chaqueña, presente en bosques mixtos o formando densos bosques monotípicos (palosantales). Por pérdida de hábitat y alta explotación, G. sarmientoi ... -
Breeding for Drought Tolerance by Monitoring Chlorophyll Content
(Longdom Publishing, 2021-05-17)Crop yields have increased substantially during the last 50 years, but the traits that drove these remarkable improvements, such as plant architecture, have a little remaining potential for improvement. New traits such ... -
Cassava common mosaic virus infection causes alterations in chloroplast ultrastructure, function and carbohydrate metabolism of cassava plants
(Wiley, 2021-01)Cassava common mosaic virus (CsCMV) is a potexvirus that causes systemic infections in cassava plants, leading to chlorotic mosaic and producing significant yield losses. To date, the physiological alterations and the ... -
Cell remodeling and subtilase gene expression in the actinorhizal plant Discaria trinervis highlight host orchestration of intercellular Frankia colonization
(2018-08)Nitrogen‐fixing filamentous Frankia colonize the root tissues of its actinorhizal host Discaria trinervis via an exclusively intercellular pathway. Here we present studies aimed at uncovering mechanisms associated with ... -
Changes in the relationship between temperature during the seed‐filling period and soya bean seed isoflavones under water‐deficit conditions
(Blackwell, 2016-12)Isoflavones have been shown to have health‐promoting activities in humans and are particularly abundant in soya bean. This study was conducted to determine how water deficit during seed fill affects the already known ... -
Contrasting adaptive responses to cope with drought stress and recovery in Cenchrus ciliaris L. and their implications for tissue lignification
(Wiley, 2020-11-12)Cenchrus ciliaris L. is a widely used species for cattle feed in arid and semi-arid regions due to good forage value and known tolerance to drought conditions. Here, we provide insights to adaptive responses of two contrasting ... -
Convergent Epigenetic Mechanisms Avoid Constitutive Expression of Immune Receptor Gene Subsets
(Frontiers Media, 2021-09-07)The gene pool encoding PRR and NLR immune receptors determines the ability of a plant to resist microbial infections. Basal expression of these genes is prevented by diverse mechanisms since their hyperactivity can be ... -
Cytogenetic evidence of hybridization in Prosopis alba, P. hassleri, and P. fiebrigii in the semiarid-humid Chaco transition
