Two collaborating teams—one led by Martin Janda from our department and the other by Matěj Drs from the Institute of Experimental Botany of the Czech Academy of Sciences—have shown in their new collaborative work published in the prestigious journal Journal of Plant Physiology that increased concentrations of salicylic acid (SA) lead to the suppression of anthocyanin production. SA is an important phytohormone playing crucial role in plant immunity. It was previously known that plant immunity inhibits anthocyanin accumulation. Our study demonstrated that SA is the key component of plant immunity affecting anthocyanins.
