Physiological characterization of four model Lotus diploid genotypes: L. japonicus (MG20 and Gifu), L. filicaulis, and L. burttii under salt stress
(Elsevier, 2009-09-25)The genus Lotus comprises a heterogeneous group of annual and perennial species. Lotus japonicus (with MG20 and Gifu ecotypes) has been adopted as one of the model legumes in genetic and genomic studies. Other Lotus species, ... -
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 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 ... -
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 ... -
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 ... -
Potencial micorrícico de bosques del Chaco Árido con distintos niveles de degradación por uso ganadero-forestal
(Universidad Nacional de Hurlingham, 2022-03-10)Los cambios en la cobertura vegetal causados por el uso ganaderoforestal pueden afectar a los microorganismos de suelo e incidir en la diversidad de la rizósfera y sus múltiples interacciones. -
Potential sources of sexuality in Cenchrus ciliaris L.: Seed fertility, environment and its implication in plant breeding
(Centro Regional Córdoba, INTA, 2021-09-13)Cenchrus ciliaris L. is an aposporic and pseudogamous apomictic species, and fully sexual plants are very rare or absent. Fertility, which seems to be influenced by environmental factors, is a character of interest for ... -
Potential Uses of Wild Germplasms of Grain Legumes for Crop Improvement
(2017)Challenged by population increase, climatic change, and soil deterioration, crop improvement is always a priority in securing food supplies. Although the production of grain legumes is in general lower than that of cereals, ... -
Producción de semillas, fertilidad y su relación con variables bioclimáticas en Buffel grass
(Asociación Argentina de Producción Animal, 2022-11-16)En Buffel grass la producción de semillas ( se supone influenciada por las condiciones ambientales Los objetivos fueron 1 comparar la producción de cariópsides por panoja bajo distintos métodos de polinización y momentos ... -
Prospective genetic gain to improve salinity tolerance in a population of Panicum coloratum var. coloratum with two different selection methods
(CIAT, 2021)Panicum coloratum var. coloratum is a subtropical grass for potentially increasing forage production in lowly productive environments where cattle-raising activities have been relocated. Heritability was estimated for ... -
Protección contra el estrés ambiental en cultivos: cultivares tolerantes y microorganismos benéficos
(Ministerio de Ciencia y Tecnología, Argentina, 2021-10)Anualmente la sequia en los campos de Córdoba reduce los rendimientos de los alimentos entre 30% 50% de la cosecha potencial, según el cultivo. -
Provenance matters: variability under saline stress in young plants of four populations of a Prosopis (mesquite) species from dry forests of Argentina
(Canadian Science Publishing, 2021-01-04)The planting of native perennial woody species tolerant to variable salt concentrations can facilitate the recovery of degraded dry forests. The objective of this study was to evaluate and compare, under experimentally ... -
La recula, como alternativa productiva en los sistemas hortícolas Pampeanos
(Facultad de Agronomía, Universidad Nacional de La Pampa, 2020-12)La horticultura pampeana, se sustenta en hortalizas de hoja cultivadas en invernaderos, la rúcula ocupa el cuarto puesto en lo que respecta a superficie y producción. En la última década, el cultivo comienza a ser importante ... -
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 ... -
Redox-related metabolites and gene expression modulated by sugar in sunflower leaves: similarities with Sunflower chlorotic mottle virus-induced symptom
(Taylor & Francis, 2013)Sugars are part of an integrated redox system, since they are key regulators of respiration and photosynthesis, and therefore of the levels of reducing power, ATP and ROS. These elements are major determinants of the ... -
Reductions in Maize Root-tip Elongation by Salt and Osmotic Stress do not Correlate with Apoplastic O2•− Levels
(Oxford Academic Press, 2008-10)Background and Aims: Experimental evidence in the literature suggests that O2•− produced in the elongation zone of roots and leaves by plasma membrane NADPH oxidase activity is required for growth. This study explores ... -
Response of determinate and indeterminate soybean cultivars to basal and topdressing N fertilization compared to sole inoculation with Bradyrhizobium
(Elsevier, 2016-08)Soybean (Glycine max (L.) Merrill) new cultivars have high N demands to sustain increasing grain yields. One may ask whether these cultivars would need basal and/or topdressing N application as perhaps symbiotic N2 fixation ... -
Respuesta de la calidad del suelo por aplicaciones de efluente porcino combinado con fertilización mineral
