In drought conditions, the capacity for retaining carbon in legume nodules is limited and this may be the reason why there is a drop in nitrogen-fixing in legumes under these conditions. This was the conclusion of María Dolores Gálvez in defending her PhD thesis at the Public University of Navarre. Her PhD was entitled, “Nodule metabolism in Pisum sativum L. in response to water stress: carbon/nitrogen interactions and the possible molecules involved in the modulation of the response”.
Nitrogen-fixing and drought
Biological nitrogen-fixing is a process of great agricultural and ecological interest, given that nitrogen, after water and carbon, is the nutrient that most limits vegetable growth and crop production. This process is particularly sensitive to adverse environmental conditions, such as water stress or drought. This is why María Dolores Gálvez’s PhD was aimed at investigating how the regulation of biological nitrogen-fixing is carried out under drought conditions.

Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.
Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....
Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
