(Universidad Nacional del Noroeste de la Provincia de Buenos Aires -UNNOBA, 2022-10-19)Una de las principales enfermedades que afectan la producción de maní en Argentina es el carbón de maní, ocasionado por el hongo Thecaphora frezii. El uso de microorganismos biocontroladores para el manejo de enfermedades ... -
Selección de materiales tolerantes a la sequía evaluando respuestas fisiológicas en una población de RILs con parentales silvestres
(Centro de Ingenieros Agrónomos General Cabrera, 2022-09-15)La sequía es una limitación ambiental devastadora que afecta la calidad y productividad de maní. Las áreas de cultivo propensas a sufrir sequía van en incremento, con un pronóstico de aumentos en la frecuencia y gravedad ... -
Selecting salt-tolerant clones and evaluating genetic variability to obtain parents of new diploid and tetraploid germplasm in rhodesgrass (Chloris gayana K.)
(2013-01)We evaluated survival percentage under salt stress in 46 diploid and tetraploid clones of rhodesgrass (Chloris gayana K.) with the aim of obtaining salt tolerant clones. Fifteen clones were selected at 600 mM NaCl under ... -
Silencing of the tomato phosphatidylinositol‐phospholipase C2 (SlPLC2) reduces plant susceptibility to Botrytis cinerea
(Wiley, 2016-12)The tomato [Solanum lycopersicum (Sl)] phosphatidylinositol‐phospholipase C (PI‐PLC) gene family is composed of six members, named SlPLC1 to SlPLC6, differentially regulated on pathogen attack. We have previously shown ... -
Sistemas de fenotipado para la evaluación de las respuestas al estrés salino en Lotus
(Facultad de Agronomía, Universidad de la República e Instituto Nacional de Investigación Agropecuaria, Uruguay, 2013-06-01)La tolerancia al estrés salino es un carácter complejo determinado por la sumatoria de los efectos de numerosos genes, cuya identificación es necesaria para la definición de estrategias de mejoramiento. En este sentido, ... -
Somatic embryogenesis from in vitro anther culture of apomictic buffel grass genotypes and analysis of regenerated plants using flow cytometry
(2014-06)Buffel grass is a fodder grass that reproduces mainly via apomixis. Using in vitro tissue culture in apomictic species provides alternatives that can be applied in a breeding program. The aims of this work were to establish ... -
Soybean pod and grain isoflavones accumulation during the filling period in field conditions
(Ediciones INTA, 2021-12)The objective of this work was to determine the isoflavones accumulation in soybean pods and grains during the filling period in field conditions. Pods of the same phenological stage (marked in R5, i.e. beginning of grain ... -
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 ... -
Structure and biological activities of lipochitooligosaccharide nodulation signals produced by Bradyrhizobium japonicum USDA 138 under saline and osmotic stress
(2014-02)The establishment of a symbiotic interaction involves a signal exchange between the host legume (flavonoids) and the nitrogen-fixing rhizobia (nodulation factors (NFs)). Likewise, abiotic stress conditions, such as salinity ... -
