We are interested in understanding how cells communicate with each other. We are using pollen tube guidance in Arabidopsis thaliana as a model system to accomplish this goal. Besides scientific curiosity, we are also interested in this process because it is essential for successful seed production.

"How are pollen tubes precisely guided to their target"– is the question

we are trying to solve. Hence, we are focused on identifying andcharacterizing the guidance signals generated by the A.thaliana pistils to guide pollen tubes to their final target in the embryo sac (Figure 1).
