Dutch researcher Daniël van den Broek investigated bacteria which fight fungal infections in plants. Spontaneous variations in the phase of these bacteria reduce the anti-fungal protective function but increase the bacterias competitive advantage and with this their chances of survival.
Scientists worldwide are looking for biological alternatives to chemical pesticides in order to protect crops against pathogens. One of these is the use of bacteria which protect plants, for example, by producing antifungal substances. Daniël van den Broek investigated how to improve the reliability of crop protection methods that use these microorganisms.
Van den Broek studied Pseudomonas bacteria. The molecular biologist first of all isolated and described these bacteria, which are found in or on the roots of maize. Of the 214 strains isolated, 46 were found to suppress the growth of pathogenic fungi, for example those which cause black root rot. In total 43 of these 46 medicinal strains spontaneously switched between the two phases.

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...
