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 ... -
Physiological and anatomical traits associated with tolerance to long‐term partial submergence stress in the Lotus genus: responses of forage species, a model and an interspecific hybrid
(2018-09)Cattle production based on natural pastures is often subject to flooding periods, which affect plant performance and as a result, forage production. Although most forage legumes are not tolerant to flooding, Lotus spp. are ... -
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 ... -
Individual and combined effects of drought and heat on antioxidant parameters and growth performance in Buffel grass (Cenchrus ciliaris L.) genotypes
(2018-11)Drought and heat stress are two critical threats to crop growth and sustainable agriculture worldwide. In the last decade, many studies focused on the response of crops to a single stress, nevertheless studying the response ... -
Early responses to Fe-deficiency distinguish Sorghum bicolor genotypes with contrasting alkalinity tolerance
(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 ... -
Land degradation assessment in the Argentinean Puna: Comparing expert knowledge with satellite-derived information
(Elsevier, 2018-11)The Puna region, located in NW Argentina, is a dry highland with many endemic species and significant traditional cultural heritage. The Puna was a pilot region for the Land Degradation Assessment in Drylands project ... -
Long-term preservation of Lotus tenuis adventitious buds
(Springer, 2018-11-14)Encapsulation-dehydration, encapsulation-vitrification, and vitrification were tested for cryopreservation of Lotus tenuis (Fagaceae) adventitious buds clusters (ABCs) obtained by a direct regeneration system from leaves ... -
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 ... -
Redox systemic signaling and induced tolerance responses during soybean–bradyrhizobium japonicum interaction: involvement of nod factor receptor and autoregulation of nodulation
(Frontiers Media, 2019-02)The symbiotic relationship between legumes and nitrogen-fixing rhizobia induces local and systemic responses, which ultimately lead to nodule formation. The autoregulation of nodulation (AON) is a systemic mechanism related ... -
Wild halophytic species as forage sources: key aspects for plant breeding
(Wiley; British Grassland Society; European Grassland Federation, 2019-02-20)The use of wild halophytic species as forage resources in saline environments has gained increasing attention. Argentina ranks third in area of saline soils in the world, with a third of its territory showing various degrees ... -
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 ... -
Glutathione, a key compound for As accumulation and tolerance in soybean plants treated with AsV and AsIII
(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, ... -
Interspecific hybridization improves the performance of Lotus spp. under saline stress
(Elsevier, 2019-06)Salinity is one of the most frequent limiting conditions in pasture production for grazing livestock. Legumes, such as Lotus spp. with high forage quality and capable of adapting to different environments, improves pasture ... -
Interactions between soybean, Bradyrhizobium japonicum and Soybean mosaic virus: the effects depend on the interaction sequence
(2019-06-25)The symbiotic interaction between soybean and nitrogen-fixing rhizobia can lead to plant growth promotion and induced systemic responses. Symbiotic interactions may increase tolerance/resistance to abiotic/biotic stress ... -
TOR and SnRK1 signaling pathways in plant response to abiotic stresses: Do they always act according to the "yin-yang" model?
(2019-08-13)Plants are sessile photo-autotrophic organisms continuously exposed to a variety of environmental stresses. Monitoring the sugar level and energy status is essential, since this knowledge allows the integration of external ... -
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 ... -
New insights into the molecular basis of induced resistance triggered by potassium phosphite in potato
(2019-11-12)This work aimed to provide data about the molecules involved in induced resistance mediated by potassium phosphite (KPhi) in potato. To achieve these, we performed microarray analysis to determine the changes in gene ... -
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 ... -
