The recent collaboration with Dr. Fabio Pasin has resulted in a new publication this September 2020 in Plant Communications with the contribution of three members of the ANTIOX Team: Dr. Maren Müller, David H. Fresno and Prof. Sergi Munné-Bosch.
The publication is entitled “Abscisic Acid Connects Phytohormone Signaling with RNA Metabolic Pathways and Promotes an Antiviral Response that Is Evaded by a Self-Controlled RNA Virus” and shows that abscisic acid is an active player in plant immunity to plant pathogenic viruses of the genus Potyviridae by affecting host RNA metabolism. These findings shed a light on the importance of this phytohormone in plant responses to viruses, whose role in this type of immunity had been overlooked until now.
