A model of photosynthesis regulation by ion fluxes in conditions of variable light

Prof Spetea conducts experiments in light of fluctuating intensity on the model plant Arabidopsis thaliana.

Prof Cornelia Spetea and her team at the University of Gothenburg, Sweden, study ion transport proteins and genes involved in the regulation of photosynthesis in conditions of abrupt changes in light intensity. Research on this topic is important because light fluctuations constantly occur in the natural environment and affect photosynthesis and growth. Their proposed model could act as a knowledge […]

When control is lost: Studying the interactions of ATP and acetylcholine in the urinary bladder

The inner lining of the bladder, known as the urothelium, triggers the reflex controlling urination.

The inner lining of the bladder, known as the urothelium, not only serves as a passive barrier but also triggers the reflex controlling urination (the micturition reflex). The neurotransmitter ATP released from the stretched urothelium activates the bladder afferent nerves and evokes the release of acetylcholine that substantially contributes to the contractile response. Prof Gunnar Tobin from the University of […]

Pipefish male pregnancy: Why do females prefer large mates?

Pipefish male pregnancy: Why do females prefer large mates?

Parental care is an important factor to reproductive success, and studies of care quality can help in understanding mate choice and other reproductive decisions. In the broad-nosed pipefish, males become ‘pregnant’ and care for their embryos until birth. Large and small male pipefish adopt different parental care strategies, and females favour larger mates. Researcher Ines Braga Goncalves at the University […]
