Dissecting the genetic control of natural variation in sorghum photosynthetic response to drought stress
(Oxford Academic Press, 2022-05-23)Drought stress causes crop yield losses worldwide. Sorghum is a C4 species tolerant to moderate drought stress, and its extensive natural variation for photosynthetic traits under water-limiting conditions can be exploited ... -
Early responses to Fe-deficiency distinguish Sorghum bicolor genotypes with contrasting alkalinity tolerance
(Elsevier, 2018-11)Soil alkalinity is a significant limitation to agricultural productivity and it is associated to several soil features, among them, Fe deficiencies. In this work, we explored the hypothesis that alkalinity tolerance in ... -
Genetic architecture of photosynthesis in Sorghum bicolor under non-stress and cold stress conditions
(Oxford University Press, 2017-10-03)Sorghum (Sorghum bicolor L. Moench) is a C4 species sensitive to the cold spring conditions that occur at northern latitudes, especially when coupled with excessive light, and that greatly affect the photosynthetic rate. ... -
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 ... -
Nutrient deficiency and hypoxia as constraints to Panicum coloratum growth in alkaline soils
(Wiley; British Grassland Society; European Grassland Federation, 2017-12)Alkaline and saline–alkaline soils impose severe restrictions on plant growth. Panicum coloratum var. coloratum is a perennial C4 forage grass widely used in tropical and subtropical environments. Published information on ... -
Stem canker caused by Phomopsis spp. Induces changes in polyamine levels and chlorophyll fluorescence parameters in pecan leaves
(Elsevier, 2021-09)Pecan plants are attacked by the fungus Phomopsis spp. that causes stem canker, a serious and emerging disease in commercial orchards. Stem canker, which has been reported in several countries, negatively affects tree ...
