Front cover of a postcard to advertise an upcoming virtual issue of the Journal of Experimental Botany titled 'Rooting 2026'. The editors are Pablo Manavella and Catharina Merchante. The issue is associated with the 11th International
Symposium on Root Development held on 4th-7th May 2026 in Specchiolla, Italy. The text reads "To mark Rooting 2026, we are assembling a collection of papers focused on plant roots. This collection brings together research spanning root development, agriculture, plant-pathogen interactions, and biotechnology."
The main image on the postcard is a hand drawn Schematic representation of the
