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 ... -
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 ... -
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 ... -
Soybean seed growth dynamics exposed to heat and water stress during the filling period under field conditions
(Wiley, 2021-05-27)Soybean production can be affected by heat (HS) and water stress (WS). However, studies on effects of stresses combination under field conditions are still scarce. The objective of this study was to evaluate the impact of ... -
Leaf Photosynthesis and Senescence in Heated and Droughted Field-grown Soybean with Contrasting Seed Protein Concentration
(Elsevier, 2021-06-06)Soybean plants under heat and drought generate a multiplicity of responses in photosynthesis and senescence, impairing growth, yield, and seed quality. The goal of this study was to analyze and quantify independent and ... -
Nivel de ADN-Ploidía en poblaciones sudamericanas y norteamericanas de la gramínea nativa disyunta Trichloris crinita (Chloridoideae, Poaceae)
(Facultad de Ciencias Agrarias, Universidad Nacional del Litoral, 2021-04-24)Trichloris crinita es una gramínea nativa de distribución disyunta que habita regiones áridas y semiáridas de Sud y Norteamérica. Trabajos previos mostraron uniformidad en el nivel de ploidía en poblaciones sudamericanas ... -
Morphological and molecular characterization of a hybrid zone between Prosopis alba and P. nigra in the Chaco region of northwestern Argentina
(JD Sauerlaender's Verlag, 2020-06-26)The Gran Chaco is the largest dry forest in South America. One of the key taxa of this biome is the genus Prosopis (Fabaceae) which contains several economically important species. One of the characteristics of this genus ... -
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 ... -
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 ... -
Ammonium stress increases microautophagic activity while impairing macroautophagic flux in Arabidopsis roots
(Wiley, 2020-11-22)Plant responses to NH4 + stress are complex, and multiple mechanisms underlying NH4 + sensitivity and tolerance in plants may be involved. Here, we demonstrate that macro‐ and microautophagic activities are oppositely ... -
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 ... -
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 ... -
Morpho‐physiological traits associated with drought responses in soybean (Glycine max L.)
