Bacillus subtilis ALBA01 alleviates onion pink root by antagonizing the pathogen Setophoma terrestris and allowing physiological status maintenance
Sayago, Pamela; Juncosa, Florencia; Albarracín Orio, Andrea Georgina; Luna, Dario Fernando; Molina, Gabriela; Lafi, Jorge; Ducasse, Daniel Adrian (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 ... -
Cassava common mosaic virus infection causes alterations in chloroplast ultrastructure, function and carbohydrate metabolism of cassava plants
Zanini, Andrea Alejandra; Di Feo, Liliana Del Valle; Luna, Dario Fernando; Paccioretti, Pablo; Collavino, Agostina; Rodriguez, Marianela (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 ... -
Differential characteristics of photochemical acclimation to cold in two contrasting sweet sorghum hybrids
Zegada Lizarazu, Walter; Luna, Dario Fernando; Monti, Andrea (Wiley; Scandinavian Plant Physiology Society, 2016-08)Sweet sorghum has a photosynthetic system which is highly sensitive to cold stress and hence strongly limits its development in temperate environments; therefore, the identification of key exploitable cold tolerance traits ... -
Early responses to Fe-deficiency distinguish Sorghum bicolor genotypes with contrasting alkalinity tolerance
Luna, Dario Fernando; Saavedra Pons, Amalia Beatriz; Bustos, Dolores Angela; Taleisnik, Edith (Elsevier, 2018-11)Soil alkalinity is a significant limitation to agricultural productivity and it is associated to several soil features, among them, Fe deficiencies. In this work, we explored the hypothesis that alkalinity tolerance in ... -
Glutathione, a key compound for As accumulation and tolerance in soybean plants treated with AsV and AsIII
Vezza, Mariana Elisa; Luna, Dario Fernando; Agostini, Elizabeth; Talano, Melina Andrea (Elsevier, 2019-06)Despite soybean (Glycine max L.) is often cultivated in areas contaminated with arsenic (As) which causes deleterious effects on its growth, little is known about tolerance mechanisms in response to As exposure. In particular, ... -
Nutrient deficiency and hypoxia as constraints to Panicum coloratum growth in alkaline soils
Luna, Dario Fernando; Aguirre, A.; Pittaro, Gabriela; Bustos, Dolores Angela; Ciacci, María Belén; Taleisnik, Edith (Wiley; British Grassland Society; European Grassland Federation, 2017-12)Alkaline and saline–alkaline soils impose severe restrictions on plant growth. Panicum coloratum var. coloratum is a perennial C4 forage grass widely used in tropical and subtropical environments. Published information on ... -
Tolerancia a la salinidad: respuestas morfo-fisiológicas en diferentes etapas del desarrollo en dos cultivares de alfalfa = Salinity tolerance: morpho-physiological responses at different developmental stages in two alfalfa cultivars
Barbieri, Giuliano; Cornacchione, Monica; Luna, Dario Fernando; Parola, Rodrigo; Rodriguez, Marianela (Universidad Católica de Córdoba, 2024-04-05)En el marco del cambio climático, la producción en suelos salinos surge como un desafío global de gran importancia, especialmente en regiones áridas de Argentina. Este estudio se enfoca en la alfalfa (Medicago sativa), una ...
