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 ... -
Superoxide dismutase and glutathione reductase overexpression in wheat protoplast: photooxidative stress tolerance and changes in cellular redox state
(Springer, 2008-08-26)In previous works, we have established a correlation between antioxidant system response and tolerance to drought, osmotic stress and photooxidative stress of different wheat cultivars with contrasting drought tolerance. ... -
Sweet corn (Zea mays L.) growth and yield are influenced by establishment methods
(South African National Biodiversity Institute, 2014-06)Six experiments were performed in the term of three years in order to explore and compare the effects of transplanting and direct sowing (DS) on sweet corn (Zea mays L.) growth, earliness and yield. Different genotypes, ... -
The Activity of the Chloroplastic Ndh Complex Is Regulated by Phosphorylation of the NDH-F Subunit
(American Society of Plant Biologists, 2003-05-01)Hydrogen peroxide (H2O2) induces increases, to different degrees, in transcripts, protein levels, and activity of the Ndh complex (EC 1.6.5.3). In the present work, we have compared the effects of relatively excess light, ... -
The Arabidopsis chromatin regulator MOM1 is a negative component of the defense priming induced by AZA, BABA and PIP
(Frontiers Media, 2023-05-09)In plants, the establishment of broad and long-lasting immunity is based on programs that control systemic resistance and immunological memory or “priming”. Despite not showing activated defenses, a primed plant induces a ... -
The chlorotic symptom induced by Sunflower chlorotic mottle virus is associated with changes in redox-related gene expression and metabolites
(Elsevier, 2012-08-18)Systemic infections are commonly associated with changes in host metabolism and gene expression. Sunflower chlorotic mottle virus (SuCMoV) causes systemic infection with sugar increase, photoinhibition and increase in ... -
The role of inoculum identity in drought stress mitigation by arbuscular mycorrhizal fungi in soybean
(2015-01)It is well known that arbuscular mycorrhizal fungi (AMF) effects on plant growth largely depend on fungus identity. The objective of this study was to test whether three individual AMF isolates and their mixture mitigate ... -
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 ... -
