High night temperature during maize post-flowering increases night respiration and reduces photosynthesis, growth and kernel number
(Wiley, 2022-03-15)In the last years globally, daily night-time low temperatures have increased more than twice compared with maximum temperatures. There is little evidence about maize growth and yield responses to high night temperature ... -
Light interception, yield, spring regrowth and quality of Chloris gayana under different defoliation regimes
(Taylor and Francis, 2022-02-22)To study the effect of different defoliation regimes on light interception, forage yield, spring regrowth and quality of one of the most expanded species in this region, Chloris gayana, we evaluate combinations of two ... -
Partial and total defoliation during the filling period affected grain industrial and nutraceutical quality in soybean
(Wiley, 2022-01-08)BACKGROUND: Little is known about soybean grain chemical composition response to defoliation. The objectives of our study were: (i) to quantify the impact of different levels and timing of defoliation during the filling ... -
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, ... -
Saline and osmotic stress differentially affects apoplastic and intracellular reactive oxygen species production, curling and death of root hair during Glycine max L.–Bradyrhizobium japonicum interaction
(Elsevier, 2011-12-08)In the present study, the production of apoplastic and intracellular reactive oxygen species (ROS) and deformations of young soybean root hairs inoculated with Bradyrhizobium japonicum strain USDA138 were analyzed under ... -
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, ... -
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. ... -
An Autophagy-Related Kinase Is Essential for the Symbiotic Relationship between Phaseolus vulgaris and Both Rhizobia and Arbuscular Mycorrhizal Fungi
(American Society of Plant Biologists, 2016-09)Eukaryotes contain three types of lipid kinases that belong to the phosphatidylinositol 3-kinase (PI3K) family. In plants and Saccharomyces cerevisiae, only PI3K class III family members have been identified. These enzymes ... -
Un análogo de brasinoesteroide confiere tolerancia a la sequía en soja
(REDBIO, 2021-06)Los bioestimulantes a base de fitohormonas son una alternativa práctica para mitigar los efectos de la sequía en el cultivos claves como la soja. Los brasinoesteroides (BRs) promueven el crecimiento y la respuesta ... -
Identification of QTLs for shoot and root growth under ionic–osmotic stress in Lotus, using a RIL population
(CSIRO Publishing, 2014-02-20)The genus Lotus includes a group of forage legume species including genotypes of agronomic interest and model species. In this work, an experimental hydroponic growth system allowed the discrimination of growth responses ... -
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, ... -
Evaluation of bradyrhizobia strains isolated from field-grown soybean plants in Argentina as improved inoculants
(Springer, 2010-09-22)Bradyrhizobium strains were isolated from nodules obtained from field-grown soybean plants sampled in 12 soybean production locations in Argentina. These fields had been annually cropped with soybean and did not show ... -
