Schematic representation of the coherent control of a spin defect (red) in an atomic layer of boron nitride. Boron nitride consists of boron (yellow spheres) and nitrogen (blue spheres) and lies on a stripline. The spin defect is excited by a laser and its state is read out via photoluminescence. The qubit can be manipulated both by microwave pulses (light blue) of the stripline and also by a magnetic field.

Spin Defects Under Control

An international research team has made progress towards improved materials for quantum sensor technology. Medicine, navigation and IT could benefit from this in the future.

During drought, the signalling molecule GABA is produced and inhibits the opening of leaf pores (left). If the enzyme GAD2, which converts glutamate to GABA, is genetically switched off, the pores remain open even during drought - the plants lose more water (centre). If the gene for GAD2 is reintroduced into the closing cells, the defect is reversed. The experiment shows that the sphincter cells autonomously perceive stress and react to it with GABA production.

Plants Remember Drought

During drought, plants use a signalling molecule known from animals to limit their water loss. The molecule provides them with a kind of memory of how dry the day was.

Violet light triggers a signalling chain in the light sensor protein switch-Cyclop, blue or green light stops the chain. At the end, the production of the signalling molecule cGMP is regulated by the enzyme guanylyl cyclase (GC).

Optogenetics: Light Regulates an Enzyme

New tool for cell biology: Würzburg researchers have developed a light sensor with an enzyme function that can be switched on and off with different light colours.
