We would like to cordially invite you to the regular Auxins and Cytokinins in Plant Development Symposium (ACPD 2023), which will be held in Prague from 25–29 June 2023. ACPD 2023 will be the tenth in a row, and for 2023 we have decided to emphasize the role of these two key phytohormones in plant response to ever-changing environmental conditions. We look forward to seeing you again.
