New role for salicylic acid
In a new paper published in PNAS on Tuesday, April 23, a team of researchers around Jiři Friml, now Professor at IST Austria, reports an unanticipated effect of the plant hormone salicylic acid on protein trafficking in plant cells. Their research, performed while Jiři Friml was still based at VIB Ghent, suggests that salicylic acid affects the removal of cargos from the cell surface through endocytosis, mediated by the coat protein clathrin. This is likely a novel independent mechanism by which salicylic acid regulates aspects of plant physiology. The research group of Jiři Friml recently moved to IST Austria.
