Phosphate (Pi) unavailability is a growth-limiting factor for plants. Under Pi-limited conditions, plants activate molecular mechanisms for better acquisition and utilization of this nutrient. In maize, changes in the expression pattern of several Pi starvation-induced genes, including the A1 coding for dihydroflavonol 4-reductase (DFR) involved in ... more
Drought stress is a serious obstacle for crop production, especially in arid and semi-arid areas of the world. Sorghum is a useful crop to grow in areas with erratic, poorly distributed or inadequate rainfall. To help determine the best alternatives, we evaluated 30 sorghum cultivars with and without water stress in the post-flowering plant stage. The work was ... more
With the advent of the Brazilian Government Biodiesel Program and the increasing demand for vegetable oils, Jatropha curcas has been emphasized as an alternative raw material. Given the known water stress tolerance of this species, we evaluated the plasticity of photosynthetic metabolism in nine genotypes of J. curcas under water stress (WS). The ... more
