Research focus

We are analysing the intercellular signalling pathways that control growth and development of plant shoot and root meristems. Meristems harbour a plant´s stem cells and determine the capacity to grow for extended periods, generate new organs such as leaves and control the growth pattern of the root system. We will characterise the differences between meristems that support annual or perennial growth patterns, identify the genes that control these traits and use them to modulate life strategies in crop plants.
